Well, I got the curious regen link USB cable. Nothing remarkable through the first night of listening. But I ran music through it for 24 hours and then sat down and listened again last night.
Pretty much everything that Rob the designer says, it will do. Most notable is the dimensionality of the soundstage. I thought I had a big soundstage going. This increases it to a notable degree. I did some A/B with the hard connector from the regen to the DAC and without rushing to complete the A/B; you could easily hear how the soundstage shrunk with the hard connector.
Smoother delivery, spot on tone, pretty much everything else he says. Foot taping, front to back separation, all that.

I need to share with you my successful experience with this incredible and astonishing USB cable.
I was not searching to replace my Totaldac USB cable, but reading on internet, I come across some positive reports concerning this little "piece of intellectual beauty".
A little package arrived few days after the order (with a 30 day back granted and return shipment fees included.) I settled the cable and started a 50 hours burn-in procedure during last week.
The cable is ready now and What I'm currently listening to is something totally new!! A large amount of details which apparently was missing or not correctly emphasized, leading to a still more correct placement of the instruments.
Tons of harmonics around the instruments that make it even more real and vivid. Great detail and fluidity that allow a relaxed listening even at high sound pressure levels.
BTW, I think the USB cable, for a computer based system, has to be considered as a "Cartridges" for analog, and as the latter, each USB cable has its own specific "sound". I still own other cables ( and still I have ), just to name a few: Totaldac, Ridge Street design Alethia, MIT....
But, in my system, Curious USB cable it is quite another league.

Previous usb cables: Lightspeed and Revelation Audio.
I've put nearly 100 hours on two lengths of the Curious USB, 28 cm into the Regen and 20 cm out of it, but it literally only took ten seconds to know that this was a keeper. My former references, Lightspeed and Revelation Audio, both in dual conduit versions, will now reside in my secondary home office system.
"Revelation" is a word better applied to the openness, expansiveness, clarity and purity of the Curious USB and these characteristics just keep getting better. It's tough to describe, but they simply deliver a more solid, stable, three-dimensional image that I instantly fell for.
I know I'm on to a good thing, when I find myself constantly revisiting old musical favorites curious to hear how they will sound with Curious cables. And that's exactly what I've been doing the past few days and what I will be doing for the foreseeable future.
Simon C. Hong Kong
Just a mere 200mm length of a connecting cable, how much of a difference was I suppose to expect?
Anyhow, after a week of listening and comparisons, I can no long sequester my observations! This kind of revelation doesn't come around that often and, doesn't manifest itself so perfectly. Ever!
The difference was noticeable immediately but, I needed time to run through my collection playing all the different types of music before summarising mine comments. Obviously, with the well-recorded acoustical music there is more to be revealed, but even with the bad ones (old or new), there is always something new to surprise me too! Also, the bass just keeps getting deeper and better all the time too!
This short piece of cable is probably the best price-performance item in my whole system!
The first thing I noticed was an overall sense of space on the soundstage and, the "un-digitizing" of the music. Even before the music starts, or during the silent moments of an acoustical recording, you can feel the space of the stage that just wasn't there nor as palpable before.
There is no rounding off or limiting of anything at all, not altering anything in the tonality but really giving each note, each tone more vibrancy, more timbral textures, more spatial richness, and much better delineations of attack and decay.
To sum it all up, the end result is a very balanced sounding cable with a very rich and lively sound that digs out every little nuance in the recording.
Sit back a little bit, widen your perspective, the whole soundstage is now deeper, wider, much much taller with vivid and solid imaging. Especially, the way-outside and behind out of the speakers imaging and, over the top and room-filling 3D cues are nothing short of spectacular too. Onto headphone listening, it's like you are not listening to headphones but still listening to speakers. A more plausible analogy to me is that it reminded me of the kind of soundstage and imaging like listening to the Focal Utopia or the Stax electrostatic earspeakers (but with my Audeze LCD-3). With some recordings, the imaging was nearly binaural and, don't forget that bass, it is extended, musical and, well defined.
A "curiously" magical cable!

I was particularly interested in the cable for the Chord Hugo due to the cable using the micro usb end. This eliminated using an adapter, so I placed an order for the cable. Upon hearing this cable in my system, results? END GAME! Holy mother of pearl! The Soundstage depth, width, left to right creates a Holy S*** moment, and I am truly done with my system, it is now materializing a 3D soundstage of my dreams with all the details floating before you. I Love the Chord Hugo and had it modified by my friend putting in larger caps and proprietary application of ERS which helped it further, but the one thing that still bothered me with the Hugo was the body of vocals and instruments. They just did not have the weight. This cable fixed that and was the finishing touch for me and I am thankful for Rob’s creation

“This current Curious cable makes my own Prototype usb cable sound false! For instance, when listening to Ian Moss sing “Georgia On My Mind” my old cable now seems to sound like a caricature or animation of the real thing. The Curious sounds ethereal and disarmingly communicative, the audience interaction on on this track is real with the Curious Cable.
I can now hear that my old reference usb cable slightly accentuates high frequency decay and is not quite the neutral conduit I thought it was. Bass with the Curious is simply SOTA with correct harmonic, reproduction which I believe is inextricably linked to a component’s handling of the low frequency spectrum. The Curious is so fast that it makes music sound very smooth and effortless, with detail and resolution that has lifted my factory reference system one more notch.
Our reference PS Audio Direct Stream DAC with Yale firmware upgrade and this new Curious usb is simply THERE. At under 400 bucks for a 0.8m length even WAF integration is good. Get one!! Fellow audiophiliacs.”
Jay J. USA
The cable arrived and I listened to it well into the night last night…….all I can say is THANK YOU for making such an incredible product! Forget break-in, this cable is a game-changer right out of the box!
In a sea of mis-information and false promises in the audio industry, it is truly wonderful to see and hear a product do EXACTLY as advertised.
The soundstage, the realism, the immersion is truly remarkable. I wasn’t listening to a track, I was spending intimate time with the artist!
This cable will no doubt be the topic of conversation at our next audio society meeting. We don’t discuss products as much as we discuss ways to become more involved with music, and your cable does an incredible job at accomplishing that.

What The France?! I have no idea what kinda shit you smoked when you came up with the idea of this cable, and I don't want to know, but please keep smoking it. So I plugged in the cable and I feel like I have been smokin' the same shit you have. From the first note of a virgin Curious USB Cable I felt like I lost my audio virginity. The brick fireplace and entire front wall my system sits proud of literally disappeared. Even with my eyes wide open! I hope you smoke more of whatever it is you do and come out with some azz kicken XLR interconnects. So besides my health and the people I love and care for I am grateful today for Rob's Curious USB Cable. And I have no doubt my beautiful wife will be grateful when I am finally able to turn my system off for the night and join her in marital bliss. Thank you Sir for a job well done. FYI: the cables your cables are replacing are the top-o-the line Audioquest USB cables.
Jan-Willem V. The Netherlands
Thanks for the quick service, the cables arrived on Monday. Everything that has been written about your cable is true: huge sound stage, very good detail and a non-digital feel. What I like most is the long decay of notes and sounds, especially on solo-piano. Swapping the hard-link for the Regen-link is a no-brainer, it is just very, very good. My previous cable was an AudioQuest Cinnamon, not a bad cable at all. This is just a whole lot better.
Thanks for more music!
Louis H. NSW, Australia
So, recommissioned the Bryston BDP-1, (purchased 2010) updated the firmware, sourced the NAS music files and……….wow!
The music has rhythm and pace, foot tapping and even got me a little emotional. Cable has to be run in, of course, but compared to what I had before, totally musical. I’ve been in this game since 1972 and I’ve heard all and sundry but to get the timing right is crucial and your cable finally seems to have achieved this.
Thanks so much for the painstaking research to produce a truly musical but transparent cable.
(Equipment is BDP-1, jitterbug, curious cable, Accuphase DC-37, C2420, DG-58, A-36, Larsen 8 speakers).
Henry K. Australia (using Curious with AQ Jitterbug)
The sound is amazing , so natural and real.
With detail and microdynamics very easy to hear.
Dynamic interplay shines, as opposed to most digital playback which has "Fast and Furious" monodynamics.
Emotion coming through, with me getting shivers down my spine (it's been a long time) when listening to "Oh Daddy"by Fleetwood Mac.
David M. USA
I received my cable today. I have about six hours of burn in so far and I had to write you. I have NEVER written any manufacturer to rave about an audio product before. This little usb has changed my digital rig significantly. I recently bought a Schiit Yggy and added a Wyred Recovery. Sound was very good. But your Curious has added a new dimension of focus, clarity and soundstage. Best money I have spent on audio gear in a long time. Congratulations.

Using Hugo DAC with Vertere usb cable
Finding a quality USB cable to match the Chord HUGO had been a challenge as the Hugo has a Micro-USB termination at the device end. The Vertere DFi is good, but any other cable such as Lightspeed requires a USB-B:micro adaptor; ugly and most of poor quality ($1.99 on eBay hardly marches a $999.00 cable, creating a weakest link).
Enter Mr Woodland and the CURIOUS, with a custom short 0.3m MicroUSB tipped made just right for a Mac-HUGO connection.
The fit is perfect, and the sound is magnificently transparent, life-like and real. I also did the A-B between CURIOUS and the Vertere & the Lightspeed, and IMHO the Curious is the better cable, with the most “musical” sound overall. Full marks!
This is the best cable for a Chord HUGO, which is a DAC that has sold an incredible number of units, but needs a USB cable to match. The “Curious” it is!

Previous usb cables: Cardas Clear, Wireworld platinum eclipse 7 usb, Furutech g2 pro usb, Nordost blue heaven and Heimdall2 usb
I have acquired both the standard Curious usb for my Berkeley Alpha system running mac pro with audirvana version 2.2.5 and the
micro version for Chord Mojo heaphone dac.
First initial impressions in comparison to the list of well heeled usb cables as listed above were of great inter note silence. There was a certain sure footedness that the Curious possessed way above the others, an endearing virue and much sought after.
Secondly a most profound lack of any sibilance and blurring of interleading notes in the music led to a far greater command
of my listening attention, thus we now step into the much sought after analogue type of replay, which we have chased after in digital reproduction for many years.
Thirdly the “prat” of the cable is exceptional and thus user enjoyment and involvement is heightened.
I could go on and wax lyrical about this cable, it is way and far ahead of everything else i have tried, a credit to Mr Woodland’s efforts

Using UpTone Audio Regen: Curious Vs standard cable
My notes on comparing the standard cable that came with the USB Regen and the Curious cable.
Track 1 – Could you Believe (Antonio Farcione & Sabina Sciubba)
The standard cable actually sounds pretty good – no glaring faults that I could discern other than a slightly lean bottom end.
However when compared with the Curious the following improvements are noted.
The bass definition improved and the bloom of each note sounds very natural. Acoustic guitar notes sound with a clarity and warmth like the real thing in the room. The body of the guitar is clearly presented as is the space it was recorded in. This was not a feature of the other cable. The vocal has a naturalness and presence that is a bit spooky. Some of the vocal notes are delivered with some power but the Curious cable retained absolute clarity without any sense of glare or overreach. The soundstage is also far more vibrant and instruments remain cleanly separated even through crescendos.
Track 2 – Make Me Smile (Steve Harley)
This track was chosen because it can sound overly bright and brittle. Well that was what it sounded like with the standard cable. Another artefact is a sense of congestion when the chorus gets going – it’s a tough test for any cable (or system for that matter).
On this track the Curious cable really showed it’s form. Whilst the track is certainly produced with a pronounced treble the Curious cable brought it to heel which was quite a surprise. Despite it being a favourite track from my youth I don’t listen to it much because of the exaggerated treble balance in the digital format. Well it’s back on the play list because with the Curious cable in place it is eminently listenable. Whilst still a bright production the sense of splashiness disappeared. The bass suddenly had body and weight that was missing previously. Better still the vocal lead and backing were so well separated that each vocal harmony line stands out like never before. The sense of air and dimension now presented removed any sense of congestion I thought was inherent in the production. Best of all it sounded relaxed and natural and very easy to crank the volume up without hardening the sound. I couldn’t do that before without cringing!
Track 3 – Walk on the Wild Side (Lou Reed)
On this track the difference was not as stark but obvious. The naturalness of the vocal coupled with a presence that puts Lou Reed in your room is quite spooky. From a black background the female chorus comes into the room with such reality that you get the feeling they are going to keep on coming and pass by your couch. The soundstage has a real sense of space and air with micro detailed reverb queues easy to detect. At the end of the track the sax part sounded a bit harsh with the standard cable but lost that etched tone with the Curious cable in play.
In general the thing you walk away with is the space and air around clearly defined and separated instruments that sound totally natural and tonally real. The micro detail adds to the soundstage and depth making the recorded room sound bigger than before. The naturalness and presence of most vocals is downright spooky. There is of course no going back to the standard cable!

Previous Cable: Mapleshade
Regarding your cable, I must say that I am mightily impressed. It replaced my Mapleshade USB cable that I hold in high regard. I consider my system to be top shelf given the modest investment. It is dynamic, exciting, quiet backgrounds, transparent, expressive, and subtle. I honestly did not think improvement was possible. But your cable took a relatively flat and lively image and added depth, clarity, micro-dynamics, a broader tonal pallet, and fully fleshed out base. The change is far from subtle. Well done!
Peter L. Hong Kong
Hey Rob, just want to let u know I received the regen link, and holly......how did u manage to come up with such a great USB cable! It is just so clearly superior to any other USB cables I tried, cheap or expensive.......
The centre stage is more real , before it was vague. Notes are palpable, and music all of sudden becomes music that I want to keep listening instead of a sequence and mixture of frequencies!
And this is only 4 hours on it!
Man, this is really good deed you have done to the bunch of us who have suffered ever since the invention of USB DAC !
Previous usb cable: Audioquest Carbon
Compared to the Audioquest Carbon I notice after several days (over 100 hours) of listening:
The above mentioned differences with the Audioquest Carbon are not night and day but taken together significant and they enhance the enjoyment of listening to my digital collection of over 6000 albums. I hear simply more of what is recorded.
Einar M. Norway
Many thanks for your cable. It unveils the potential of my Chord Mojo. The Mojo sounds stunning with your cable.
Orjan B. Sweden
Previous cables:AQ Cinnamon, Wireworld Starlight 7(AQ adapter, Nordost Purple Flare). I bought this Mojo cable for a friend, but trying it in my system I realised I had to order one for myself as well.
It took some 2-3 hours to start opening up but then I found myself being touched by the music in a way I have never heard in my system. Cesaria Evora´s Sodade nearly made my tears come. My previous Nordost Purple Flare was without formal faults but I could never have expected what was to open up with the Curious.
It´s like a new system, even my somewhat dull and clinically sounding Martin Logans are playing music now. Rhythm, openness and a very touching feeling.

Previous usb cable: Purist Audio, Furutech
Your cable will definitely not be coming back to you. All other USB cables I have tried (stock, gold plated, Purist, Furutech) there were tradeoffs and subtle differences (my preference being the Purist - made nice with vocals, but stifled highs) and to be honest the differences heard were splitting hairs and had me doubting. Not so with the Curious. The improvement was jump out and grab you by the shirt noticeable. As advertised the cable did bring the sound closer to analog sound. However the most surprising impact is the depth of sound being layered front to back. How this cable in the chain makes the front to back imaging almost as clear as the left to right imaging I can't comprehend. I did not even know digital could do this.
Excellent product, a true game changer.
Gary P. USA
Rob, your cable is bloody awesome!!
1. Holographic sound stage with genuine depth and layering: Freaky good!
2. Clean, smooth(SO SMOOTH) and detailed sound: Hearing things I haven't heard before
3. Fleshed out, rounded vocals: Spooky good
4. Deep, extended low frequencies with excellent definition: Complete eye opener! Wow
5. Foot tapping involvement: That's the best part!
6. A step up in realism: Sounds like the music is being played in my room!!
David P. United Kingdom
Cables have been in place now for well over 50hrs and are continuing to amaze me with their relaxed presentation. The Wyred4Sound MS-2 > Curious 0.8m USB > W4S Recovery > Curious Regen Link USB > Devialet D400 is a winning combination in my books. It replaces a 1.0m Transparent Audio Premium USB link from my Music Server > D400 and there is a marked improvement in the SQ. I am not the best at describing differences in sound quality, but suffice to say that the Curious combo makes for a more perceived (I don’t think its my ears) relaxed listening experience.
I have tried the Curious 0.8m USB in direct comparison with the Transparent USB and again there is a distinct improvement with the Curious – less digital “grain”, smoother and more relaxed.
Many thanks Rob for a very good product.
Roy P. United Kingdom
Received the cables here in the UK a couple of weeks after ordering. Plugged the 0.2m cord between the Mytek Brooklyn and the Wyred4Sound Recovery first replacing the factory supplied cord. Instantly separation improved especially percussion. On swapping my Chord cable between my modified Mac mini and the the Brooklyn the separation took another jump upwards. The whole sound seemed to gel better - starting and stopping quicker and became more involving to the point where I forgot I had swapped the cables and just listened to the music. Can't recommend them enough. It will be interesting to see if the sound changes as they bed in?
Thanks again for sending the extra cable, it opened up the sound quite nicely compared to the standard cable I had connected to the external hard-disc.
I have been able to listen longer to both cables now and I find the overall sound to be natural, open and well defined without ever becoming edgy. There seems to be a nice balance between letting you hear all the information and at the same time they never fatigue. I can listen continuosly for lengthly periods of time due to a certain smoothness they have but don't have the feeling they are "warm". Well balanced is a good way to describe them I guess, you hear all the information that comes across in a very natural and logical manner.
Steve Z. USA
I received your Curious Cable replacement for the solid link supplied by Uptone Audio for their REGEN device.
Literally cold out of the box (long truck ride in wintery cold Montana) there was no comparison -- the Curious Cable sounded much better than the REGEN's solid link. Richer, more holographic, and most importantly, more natural.
A slight edge or hardness I had been hearing on some recordings (and which was probably there even with recordings I thought were excellent) is completely gone and I can honestly say this is the best I've ever heard digital music sound in my home.
Thank you very much for such a great product at an affordable price. Very well done!

Previous usb cables: Nordost Blue Heaven and Audioquest Carbon
"To say I was impressed with the Curious would be an understatement. Better inner retrieval of detail, a more open spacious sound, smoother, but at the same time I had more clarity in the sound. The individual instruments are now easier to define & sound a lot more natural. This cable just makes my system sound right"!
John W. Chicago, USA
Previous usb cable: Mapleshade
I don’t need to listen critically to recognise a distinct improvement over my existing Mapleshade USB cable. The USB runs between an Aurender X100 server and a Luxman DAC-06. I like the complexity of percussive rhythm in some African musics, and this makes the interweaving of polyrhythms significantly easier to follow. After I’d paid I kicked myself for letting myself be seduced into what was unlikely to make any audible difference, so far as I could understand. Well, I un-kick myself!
Tim P. USA
Previous cable: Audioquest Diamond
I have had a good while to live with the cables and it just confirms what I initially heard and the other reviews. The clarity of tone, or correctness of tone is a stand out, as well as the greater 3-dimensional aspect of the sound. This adds to the realistic felling of the music and for sure the enjoyment. This is the most analog sound I have been able to achieve after going through several really good cables - and at a great value.
Thanks again for the great product and service.

Previous usb cable: Nordost Blue Heaven
I had never really considered that I needed anything better the a good quality USB cable because from a technical point of view it’s all just ones and zeroes right ? Then a friend of mine loaned me a Nordost Blue Haven cable and this made a difference and was definitely better, I spoke to Hugh Danvers Thomas about this and he said that I should try “Curious USB” as he knew Rob and was sure that it would be much better again. What a revelation ! Computer audio went from something that I would just play in the background to something totally engaging and comparable with my CD Player. The Curious USB cable opened the sound stage right up and breathed smoothness and detail into the music and removed the digital glare at the same time, Rob has certainly got it right with this cable. I would consider this cable a sound investment , and for the price I would challenge anyone to find a product that makes such a dramatic improvement.
Vice President, Los Angeles Orange County Audio Society
Let me share with you my thoughts on your cable so far. This is compared to the Audioquest Coffee, Audioquest Diamond, Furutech GT2, Wywires, and Dynamic Designs in my personal system:
The very first impression, fresh out of the box (by the way, excellent presentation with the box...very nice opening experience!), was that this cable has a fuller, darker and richer musical perspective than any of the USB cables I have on hand. The weight of the music was the first and foremost quality that I noticed. In fact, with no hours on the cable, I did feel the sound was closed in, but that changed quite a bit with some decent hours on the cable.
With more hours, the cable opened up to a beautiful bouquet of balance between detail, resolution, tonality, texture, musical weight and openness. If a system is extremely resolving with reference quality detail, I feel that your cable brings qualities to USB based audio that I have simply not heard before from any USB cable. The notion of weight, texture and tone through your USB cable is more closer to the turntable setup I have rather than any other digital cable I might have. You see, I did not ever think that a USB cable can bring these qualities to the table as I thought the USB method of connection itself was flawed. Your cable has proven otherwise. It does not have the artificial brightness masquerading as resolution. It has very natural colors and shadings of instruments with wonderful authority. A sound has an excellent transient development from beginning of the note, the middle and then through to the decay. Total naturalness.
In my experience, the only other line of cables that have reminded me of this full bodied texture and tone are cables from Harmonix Japan. No other cables, including my reference Jorma cables (USD $15k for 2 meters!) have this level of weight inherent in the design. But my reference cables are so neutral that the let these qualities through.
Next, typically, if a cable has qualities of warmth, weight and texture, they tend to lose out on transient response. NOT SO with your cable. How you are doing this, I do not know, but I can hear it and am quite taken aback by this quality. I look forward to hearing more of your work Rob! You have a winner here as far as USB cables go. Bravo!
Rolf S. Germany
I inserted the Curious and I have been enjoying musik for several hours now but it took only a few seconds to hear the difference.
I'm not a native english speaker but I try to describe my impressions.
It sounds very clear and natural easing the perception of dimension (width and depth of soundstage as well as location of instruments and musicians). It feels like removing a frame allowing the soundstage to open up.
I can hear more details and improvement in fundamental tone as well as overtone. So voices and instruments (and their individual character) sound very "real". Better timing, improved transients and decay as well as impulsive energy (fast and textured bass) make the sound more livelike.
At the same time I noticed reduced harshness and reduced artificial glare leading to better perception of micro dynamics.
Altogether musical emotion is transported in a much better way.

Previous cable: Audioquest Diamond
Put another 24 hours on the Hugo link coming out of the Regen and its amazing. I was never a true cable believer, but my system sounds fantastic. Just listened to a DSF file of Muddy Waters, Folk Singer and it was the most live performance in my living room I've ever experienced. Please use my testimonial as a reference. I had an Audioquest Diamond and sold it at a discount and still had money left over after buying the Regen and Hugo link and the quality is no looking back. The difference is really noticeable. Instruments sound like real instruments and the dimensionality is every much what people describe. If anyone has a Hugo/Regen/Jitterbug chain in their computer audio system, they will be more than pleased with your combination of cables. Well done.
Brian R. United Kingdom
Having connected my Regen link to my system I was shocked to hear such a marked improvement in the sound heaven knows what it will sound like when it is fully run in! I won't spend time in describing the difference is sound as other posters have all ready done this. If you are market for a USB cable then look no further. The cable arrived very quickly and I was pleased to receive a personal email from Rob rather a generic one. Saving now for a longer length cable to replace my Chord!
Achille M. Italy
Tuesday November 8 - the cables in question were delivered, I made them burn for about 70 hours and after I started my listening sessions. I state that I own an audio system composed of Auralic Aries as digital server, Schiit Audio Yggdrasil (in my opinion the best DAC on the market and working at a very high level of resolution) as a DAC, Pass Labs X1 as a preamplifier, Jungson JA-100 Luxury Edition as monophonic amplifiers and Usher AC-10 as speakers. The signal and power cables are Air Cable top of the range. So it is a very high resolution system.
Before you buy your cable I used a Audioquest Carbon from 0.75 meters to connect the HD to Auralic and Black Cat Silverstar between Auralic and Yggdrasil.
Well, all your cables have operated a Copernican revolution, I was virtually deaf and blind and it's hard to put into words how it sounds now my system, everything looks sharp and well defined before it was one in grayscale display now is a big screen in technicolor, the sound that first appeared dry now is liquid; tonal separation between the various instruments is impressive, the bass have an indescribable definition and depth and there is a live effect and a presence breathtaking, as far as i can tell treble I've never heard anything so refined, the vocals are a unique smoothness and beauty. The dynamics and especially the micro dynamics is monstrous. And finally holography of the sound stage is spectacular, before I had a flat and boring scene, now the musicians have materialized in my listening room, you would not believe! Rob you're too modest, in my opinion you are a true genius, all your cables are beyond imagination. I'm not a fanatic, but only an audiophile enthusiast who expected so much and got so much more.
User reviews of the Curious Cables usb cables
Larry P. Sydney Australia
Previous cable: Audioquest Diamond
I am a true analogue man and put a lot of time, money and effort into the turntable and record listening side of my musical enjoyment. So, I ventured into digital (I call it computer music cause that's what it essentially is) and bought a Burmester 113 DAC and an apple air laptop and a cheap USB cable and gave it a whirl. Well, I was intrigued by how good the sound of hi-res files was and thought that maybe a better XLR interconnect between the DAC and preamp and a better USB cable would be worthwhile. So I added a Nordost Valhalla balanced cable to the preamp (and really noticed that difference) and then went for Audioquest's highest level Diamond USB (some nearly 800 bucks of USB cable) I did notice a real difference with the Diamond in the mix, but something was still missing - that analogue depth, space and musicality!
So a chance conversation with an old friend, Rob Woodland, brought me to his Curious USB cable. I've known and trusted Rob for many years and when he offered to send me his Curious USB cable for a no obligation trial I said yes for course! Well, when I inserted it between the apple USB output to the input of the Burmester and played the hi-res file I was just listening to through the Audioquest Diamond. I was taken aback - all of a sudden the soundstage widened and opened up, the midrange was smoother and more defined and the low end was more well-articulated and overall the sound was just "nicer" and more musically involving. I listened with this wonderful USB cable for about a week before re-inserting the Audioquest Diamond USB and the soundstage went flat in comparison, the quality of human vocals, both male and female was harder and lacked the space around the vocals that the Curious had demonstrated.
So I have since sold off the Audioquest and bought Rob's wonderful Curious USB cable. I would highly recommend them to anyone wanting to achieve more music and realism from their digital system!

Previous Cable: Light Harmonic Lightspeed.
Well….my Curious Regen USB cable arrived yesterday. I was hoping for, and prepared for, a modest improvement over my Lightspeed USB cable which had bested all other USB cables I’d tried. At a mere fraction of the price, it would then represent a tremendous bargain and maximum bang for the buck.
WOW!!! The Curious cable, right out of the box, was so obviously better, IN EVERY RESPECT, that any comparison is moot and nearly useless.
Timbre, transparency, resolution, 3-D holography, tonal accuracy, bass extension, weight, impact, and you-are-there palpability etc. etc. are in a completely different league from any other USB cable in my experience. To borrow from Sam Tellig: “There is simply more “there” there”.
Mark H. Ireland
What can I say? The word "stunning" comes to mind, and I do not offer it lightly. The only cable that has ever made a similarly stark difference in sound for me is the PS Audio AC-12 power cable which - running at over €1,000 offers nothing like the same bang for my buck as your USB cable. For the last several months I had been agonising over whether I should finally ditch the mac mini and go with a dedicated front end from Aurender or Antipodes. That may yet happen in the future, but the addition of the Curious USB has certainly taken the urgency out of that decision :-)

Previous Cable: TotalDac usb
I just received your cables and paired with the Regen, it is excellent even before any real burn-in. More air and space. Better fine detail. It is better than my TotalDac USB cable. I will be keeping it.
Artur B. Canada
Thank you for this fantastic product. I'm using in total three of your cables in my system, two 200 mm for my hard drives and Regent link between Regent,Audiophillio and Chord. I find this combination most analog sounding, it is perfect. People should remember that for hirez comp music best is to use softer sounding tube amp with vintage army tube selection. Cables are as all reviews described, more dynamics, detail, dimension soundstage, closeness to music and performer. It is funny but adding this cables I compare to value of $ 10,000 or maybe $20,000 upgrade on speackers or amp. I think that your cables are the best usb cables available on the market today in any price range.

About 3 weeks ago I got the Regen Link and I really liked it so I decided to try the .8m usb which I received 2days ago, I've been playing since then. Let me just say that it was the best audio upgrade I ever made for my system. My kef ls 50 sounded never better until now. Your cables are simply amazing in every aspect in audio quality.

I'm writing to you today to report on my findings for the Curious USB 0.8m, which replaces a Tellurium Q Black USB Cable. Comparisons are done by auditory memory as I have since sold the TQ Black USB. The initial listening was done right out of the box, and the subsequent listening session was done after 40 hours of burn in using the burn in CD from Tellurium Q.
I was expecting a great leap in SQ right out of the box, as the USB3.0 Link and Recovery Link so awesomely demonstrated. However, the Curious 0.8m failed to do so out of the box. Granted, bass was slightly deeper, but the vocals and instrument positioning seemed messy and unfocused. Layering was flatter and detail retrieval was, at best, on par with the TQ Black. To be honest, I was slightly disappointed and switched over to watching movies instead.
After 40 hours of burn in, I was pleasantly surprised with the improvement the Curious 0.8m made. Imaging was sharper and placement of instruments seem to be on point. Detail retrieval seems to have stepped up a notch and background seems to be darker. Sounded more 3D than right out of box. I was happy to have given it a chance and not return it. A friend of mine came over with his music server (Lumin D1) and did some comparisons with my computer setup. While is was apparent that my computer source still lost in terms of liquidity, layering (especially on DSD playback) and depth, the gap between a high end music server and consumer PC source closed considerably to the extend that I actually preferred certain songs on my PC setup.
The Curious USB did well in besting the TQ Black USB, which IIRC, had won Product of the Year a couple of years ago and was highly reviewed in some British Hi-Fi publications. Of course, TQ has their Diamond range which is supposingly on a different level altogether, but that range would cost well over a thousand bucks, whereas the Curious 0.8m only costs $340, which, IMO, presents a very value for money buy. Outstanding!

The Planets have a great soundstage, but this was an obvious improvement, both clarifying and solidifying with the Curious.
I have an improved appreciation of these little speakers now!
These have a great sense of space and separation from all sorts of listening positions, Curious has anchored the presentation, I think by
tightening the lower register and allowing the top to breathe.
It sounded like I had dropped in a better amp the improvement was to that degree.
The sound has more punch and is more forward together with the nice soundstage the enjoyment factor was there from the start.
The optical output was obviously not up to par compared to the Curious usb.
The discovery and discerning of different notes in perhaps a guitar solo or bass is a pleasant surprise.
Always pleasant when you hear new things in your favourites.

I think that your Curious cables are the greatest value in audiophile USB cables on the market. In comparison to one of my previous cables -- the Light Harmonic Lightspeed USB -- your Curious is significantly better at a third the price of the Lightspeed, and the Curious also bests the Audience AU24 SE USB cable which received a glowing review from Robert Hartley of The Absolute Sound and was until now my reference cable. Remarkable performance.

Here's to let you know the Regen Links finally arrived today! Thank you! First impression: wow! Bigger, deeper soundstage, instruments and vocals have more weight and body, dynamics are improved and details are now somehow more organically integrated in the whole musical picture (more alive). And that is just after a couple of hours' listening. The most important thing of all (and always the best sign for me): I just couldn't tear myself away from my listening seat! All of the above in comparison to an audioquest carbon usb cable.

Last week i received the Curious usb Regen Link and installed it between the Uptone Regen and my iFi iLink (usb to SPDIF converter) as a replacement for the Uptone supplied hard connector.
Power for the Regen comes from a high quality sBooster P&P Eco 6V.
The iLink is connected to my Accuphase DP-400 with a MIT Terminator 3 digital interlink.
I was planning to write a list of all the improvements from the Curious usb Regen Link. But that list would become too long, because so many Audiophile parameters are improved. So I only mention the things that stand out the most to me :
Before the Curious music from my Mac-mini already sounded better than music from the internal DP-400 CD player.
With the Curious usb Regen Link music from my Mac-mini sounds way better than music from the internal DP-400 CD player.
