“To tell the truth, I forget that it exists, so transparent it is.” — Michel
Votre cable usb continue de relier mes Dac et streamer Holo Holo avec bonheur. A vrai dire j’oublie qu’il existe, tant il est transparent. Le plus troublant est de percevoir la vibration de l’air après l’extinction d’une note de piano. Le problème est que chaque progrès vous entraîne vers une autre amélioration sonore possible, insoupçonnée jusque-là.
Your usb cable continues to connect my Dacs and Holo Holo streamer happily. To tell the truth, I forget that it exists, so transparent it is. The most disturbing thing is to perceive the vibration of the air after the extinction of a piano note. The problem is that each progress leads you to another possible sound improvement, unsuspected until then.

“Our customers love the cable.” — Dan
We purchased some of the Audiocadabra Xtrimus SA2405 Solid-Silver StarQuad Cable, from you back in August 2020.
Our customers love the cable, and in turn we do plan on coming out with a line of cable assemblies based around your cable.
I wanted to reach out and see if there is a spec sheet that you could provide for the cable? I believe you had sent one previously, but I’m unable to find it unfortunately.
We don’t have plans to purchase additional cable just yet, but are looking to move forward with our preliminary design processes and once we have the spec sheet we will be able to move forward!

Everything is ok. I’ve received your cables today. Thank you for very fast shipping.
They are already installed, USB cable-1 is connected from my matrix element h to SOtM tX-SBhubEx and USB cable-2 from my SOtM tX-USBhubEx to my Dac Gustard 20h.
I’m listening to them for 3-4 hours now. My first impressions are (sounds) very good.
Update: I received the RCA cables today: it was very very fast, packed carefully. Thank you very much for everything.
I’m happy to repeat my order too. Actually i’m using an old rca cable : a nordost flatline blue Heaven cable

“Your cables are a perfect fit in my system!” — William
I received the IC’s last week. Just like the others, perfect!
I’ve included a picture of my current system.
Streaming Tidal/Roon thru a Nucleus.
Your USB cables to a Chord 2Qute.
Your IC’s to a Vista Audio Spark amplifier(Dayens?).
SR Core speaker cables to my new Omega 3i’s.
Everything isolated, good Furman power, acoustic treated desk area.
Your cables are a perfect fit in my system!
The controlled high’s I’m looking for and controlled sharp bass.
The little Spark is a good match with the Omega’s.
They have broken in well together.
I get to do this 3-5 hours a day! I get my exercise too.
Sorry, I’ll change the screen on the monitor to your site and re-take.
Any chance you have a returned set of 4-5′ speaker cables I could demo?
I’ll pay for shipping and handling.
I like my SR Core’s but if I had a chance to try yours I would.
just a thought…

“My ripped cds played on my Allo Usbridge connected to the dac of my amplifier (Audia Flight Three S) sound the same as my cd player” — Jérémie
I received the cable today: it was very very fast, no customs fees, packed carefully. Thank you very much for everything.
I am not a specialist but to my ears, my ripped cds played on my Allo Usbridge connected to the dac of my amplifier (Audia Flight Three S) sound the same as my cd player (Creek Evolution 50CD) . I can not really hear a difference.
The IT I use between amplifier and cd player (Xtrimus2 SuperQuiet another customer sold me after making a mistake in his order) sound excellent as well.
I am now considering buying the speaker cables. How would you compare them to Tellurium Q Black II?

So far, so good! The IC’s and USB cables are keepers!
I have a desk setup in a sound room next to our bedroom. It has been treated well!
I knew silver wouldn’t be bass crazy and I guessed right.
Nice crisp highs! Tons of detail! Wider soundstage!
And, they sound great with my new SR Foundation speaker cables. A very good match!
Coax is the missing piece and it’s due Wednesday.

“I invited a customer of mine over for a listen. He was enthralled with the cables affect in my system. Job well done Sir, very well done.” — Charles
Hooray !! Received cables yesterday. Thank you.Out of the box sounded VG. Comparing them to Swiss Cable Co. ICs. Will report back.
We at Rollo Audio in NYC USA love the Ultimus 4 IC. We carry these brands, Lamm Industries, Aqua Acoustic, Audio Hungary, QLN, Kuzma, Vinnie Rossi, Innuos and more. Our demo system never sounded better. These cables are KA BOOM for the buck. Forget the expensive cables theseare as good orbetter. Try one. You will not be disappointed. Great work Audiocadabra, well done.
Update: Very impressed with cables. Will be putting in another order shortly. The speed, clarity and linearity are spectacular. Big open sound stage. Excellent timbre.
I invited a customer of mine over for a listen. He was enthralled with the cables affect in my system. Job well done Sir, very well done. I can only imagine what an entire loom from source to speaker will sound like. We shall see I mean hear.
Our customers are beginning to order from you as we have gotten the Ultimus 4 around for demo. With Covid-19 demonstrations are few however still on going. We are happy to recommend your cables.
BTW 200 hours was the break in period until it stop changing. Sounds glorious. Thank you again.

“Pleasantly surprised to see how good it performed.” — MD Hoq
Hello, I received my Ultimus4 USB cable a few days ago and was pleasantly surprised to see how good it performed. I wanted to leave a positive feedback/review on your website but could not figure out how. I would like to know if you have any plans to make USB cable that connects a portable hard drive to a PC or a streamer. Also, what about subwoofer cables and power cables? Thanks for making great products at competitive price. Keep up the good work!

“But I’d say my new Audiocadabra is superb.” — Duy
Arrived safely after so so long journey from India – Germany – UAE – China – Korea. Crazy UPS!
I’d do the comparison test your USB cable with the Nordost Heimdall 2. Not only me but my friends have to say Audiocadabra performance is pretty good. 9/10 with the well know Nordost cost about USD 600.
I had the previous model also(dual head type), the old one already very good, I’ve tested, very close to Nordost Heimdall 2.
For this new USB cable, exactly as per manufacturer described, sound more open, more airy, more 3D soundstage. Pretty close to my Japanese Kripton UC-HR and even Wireworld Platinum Starlight 7.
There are many people still doubt on expensive USB cable really can improve sound. For me, I’ve tried 5,6 different USB cable and found them really have different sound. But I’d say my new Audiocadabra is superb.
By the way, I’m looking for a good price of silver core phono cable, do you have this.
Update (after 6 weeks): Everything improved significantly. I sold all of my other USB cable i have and just keep only it.

“What is most important to me is that it is very musical. It is transparent allowing the performance to come into the room.” — Raymond
I find that the most apparent quality is a fuller, warm lower middle, and the timber (character/quality), the visceral character of the wonderfully pleasing bass tones.
Staging is excellent. Precise and three dimensional. Even better than the previous cable. The top is warm and most pleasing. What is most important to me is that it is very musical. It is transparent allowing the performance to come into the room.
I have to say that, except for the fuller, warmer middle, these are mostly subtle differences when compared it to my previous, very excellent, copper Audiocadabra cable. As with any audio component, its characteristics are realized and appreciated best with prolonged listening. That’s why wanted to take several days before replying.
I have found this to be an extraordinarily fine audiophile cable in all respects, well worth the wait. I’m extremely grateful.
Update (after 6 months): I had planned to A B the new cable with the previous ones, but I found it to be so transparent that there just didn’t seem any point to it.
I can’t imagine a more positive quality to say about any audio equipment. After listening these many months, for hours practically every day, I have not detected any hint of an extraneous quality, just the visceral experience of pure music presenting itself in my living room. A miracle that never fails to astonish, humble, and thrill me.
I wasn’t aware of how exclusive the cable was. It certainly is very special and I’m very glad I waited for it. I’m deeply grateful.

“As good, maybe even better than the Morrow Audio.” — Robert
I hope that you are well and keeping safe.
Last week I inserted the three cables into the system. I played a special burn in track on a Sheffield Lab. Disc that I have owned for years. The track was 12 minutes long. I had it on continuous repeat for 12 hours.
The cables now sound superb. As good, maybe even better than the Morrow Audio. An added bonus was that to play the track I needed to connect the Melco Library to the Dac with the USB cable so it too was well burned in.
I am now very happy. Soon when I have access to the camera I will send photos. Meanwhile please send me updates on cables. If anyone else moans or has reservations about your cables tell them to do as I have done.

“Got very good results in terms of more presence, more defined bass, superior overall detail and soundstage. .”—Vincenzo
A quick email to say that the ultimus 4 rca cables are a definitive keeper. I tried them on 4 different systems for over 50 hours and got very good results in terms of more presence, more defined bass, superior overall detail and soundstage. Have not tried the usb cable yet, I change one component at a time 🙂
I am keen to try your speakers cables. Any chance you can make one or two sets for me ahead of official release?

“It took some time burning in but what a fantastic cable.” — Menno
It took some time burning in but what a fantastic cable. Thank you very much.
It took more than 200 hours for the cable to sound good to me. It went up and down in sound quality during that time and sounds maybe still a little bit thin in the middle but very open and emotional. And I think it will still get better.

I absolutely love these cables. It is just startling how much clearer and more detail I hear with your cables. I thought the ones I had were great, but they just sound dull, masking the music, by comparison.
I look forward to receiving my next cable.

“I can hear the improvement immediately.” — Duy
I received usb cable yesterday, without the need of burn in process, i can hear the improvement immediately. More soundstage, very silence background. Even some of my friends in a most reputation audiophile forum do the test with the 4 times more expensive Heimdall 2. Audiocadabra cable almost at the same level. Heimdall 2 give a little more decent in bass, when listen very careful in a monitor system, in normal listening experience, hard to pin point the difference,they said.
Wish your business better and better to bring more value to stereo communities.

Product: Audiocadabra Ultimus3 Analog RCA Cables
“My analog sounded like I had just replaced my cartridge.” — Edgar
The cables were light and looked delicate and the RCAs are weighty – the combination looks good to me.
I replaced my Acoustic Zen Wow RCA that connects my Phonostage to my Preamp, and right-out-of-the-box the difference was very clear: clarity and weight doubled.
My analog sounded like I had just replaced my cartridge (which I am planning to do anyway).
These are beautiful, though need a bit of work to lay since they are light and tend to curl – but not a problem with me.
I will soon order 2 pairs more of the same, PLUS a Balanced pair, and maybe a USB to replace my Diamond USB (which I have been loving since it replaced my MIT).

“I am amazed at the increased clarity and detail in my system. It’s like I changed a pair of interconnects – much more than other digital cables I have tried before.” — John
I received my cable and installed it yesterday. I have tried other affordable (under $100) USB cables before and not found much difference but your cable is another story! I am amazed at the increased clarity and detail in my system. It’s like I changed a pair of interconnects – much more than other digital cables I have tried before.
One thing I determined that I did not know is that my new DAC (Aqua Formula) does not require the USB power to be connected at all. I’m wondering if I should have you build me a USB cable that doesn’t have the power lines even connected (so they I don’t need the dual heads).
Could you offer me a special price to order another cable?

“The stereo sounds so good, I feel like I don’t want to mess with things, so it will stay in my system for a while longer.” — Frank
I’ve been listening to my system quite a bit of late and after around 5 days of breaking in, I feel like the your Ultimus3 USB cable is a fantastic audio upgrade to my system.
As good as the Optimus3 is…and it is the best sounding USB cable I tried until now.….This cable has even better resolution, better imaging and further refinement of the sound of instruments, such as string instruments and piano. Dynamics are also a bit better, especially micro dynamics. Maybe not huge differences and to many, maybe not a big deal, but here, it is.
Regarding the intermittent popping noise I have been hearing, I pulled out an iFi Purifier2 I used a while back an connected it to the USB side of my DAC and no more popping. I’m not sure why this is the case, but most guys I know that listen to computer base systems have experienced this, even if they aren’t using USB. This is it.
I started using the iFi device with the Ultimus3 and haven’t removed it. The stereo sounds so good, I feel like I don’t want to mess with things, so it will stay in my system for a while longer. However, if you wish, I will pull it out at some point to give you feedback for how the Ultimus3 acts in this regard.
In any event, I am very pleased with the Ultimus3 and thank you, once again, for your great service.

“These cables are dead-quiet, smooth and revealing.” — Tony
You will be hard pressed to find a better product at a better price. I purchased four Audiocadabra USB cables for various systems in my home, and my confidence was well rewarded. These cables are dead-quiet, smooth and revealing. They are quick starters but as with any cable, they will improve with break-in. However, even cold, the difference was instantly noticeable. My son, who got one for his system, also reported instant improvement. Communication was great. Delivery was swift.
There’s a reason I bought four of them. Good guys. Unbeatable prices. Fast delivery, too. You may have to deal with a small import fee. Even so, major bang for the buck. Well done!

Product: Audiocadabra Optimus Plus Analog Cables With ETI BulletPlugs
Unsurprisingly, they’re great. My first impressions are that generally they convey more of what I want (speed, definition, ‘air and bloom’ and overall realism) and less of what I don’t (glare, smear, murkiness, etc). They’re probably nearing the 50 hour mark of playtime at this point; I will leave them running over the weekend for your recommended 100 hour break-in period.
Thank you for the follow up. I hope to get the speaker cables soon, and look forward to trying your power cable at some point as well.

“They just sound very natural. I like these cables very much.” — Guang
The Audiocadabra Solid-Core Silver Analog XLR Cables sounded very opened and with good resolution. The sound stage is bigger and the sense of 3D is elevated. I feel that these cables suit musical genres like orchestral and opera very well. The highs are smooth, extremely airy and never fatiguing. I can listen to them for long period of time without any problem. The bass and overall frequency range is well balanced. They just sound very natural. I like these cables very much.

I like your cables. It sounds really good. But it’s such low priced, that you will kill all the market! Especially with additional free postage. That’s incredible!

I am starting to love this cable, It has really started to come alive. I am a little over 50 hours. The soundstage is bigger, bass is deeper and the instruments have more sense of space, very focused. I can’t wait to see what it does after 100 hours. Thanks.

“This cable is an extraordinary bargain.” — Jørgen
After having burned in the Ultimus 3 solid silver dual-headed USB cable for about 200 hours, I have only one thing to say about this cable: Impressive!
Right out the box it sounded smooth and detailed with the same level of resolution as my reference USB cable, a single-headed TZ Yun Red which costs three times as much. After burn in, the Ultimus 3 surpasses this cable and delivers a very organic, analogue and balanced sound. It’s an epitome of neutrality.
So the Ultimus3 far exceeded my expectations given the price. This cable is an extraordinary bargain. Period. The workmanship is also stellar. Highly recommended!

“Suddenly, everything is crisp, much clearer, more focused!”—Radha
Feels as if a smoke screen has moved out, as if my specs just got corrected, my camera lens got calibrated… Suddenly, everything is crisp, much clearer, more focused!
The Musical Fidelity V-DAC II was finally connected to my Stereo system using the Audiocadabra Optimus USB cable. There was a delay in downloading an appropriate 24 bit player and format converter for Mac. In fact, it took couple of days to figure out the right combo. I have narrowed down to ‘Audirvana’ for playing and ‘XLD’ for format conversion.
Here are my observations now:
- I am listening to music for longer hours.
- The music is no longer ‘in-your-face’.
- The Old Hindi songs especially sounded like Vinyl and more ‘Live-like’.
- 24 Bit tracks, though I could not really feel the extra resolution, was very good. Especially the ‘Georgio Giovani’ Track.
Let me begin with thanking you for all your help and advice which is helping me tremendously in upgrading both my Stereo and my understanding of the subject. All the recommended tweaks have helped in improving the image, and was apparent in every stage of implementation.

I received your cable today and it works well and sounds good, even fresh out of the box. Even with the cable plugged into my iMac, it sounds great. Real open and real dynamic!! The cable is the best I have of four…by a long shot.
The cables sounds great. Maybe the best cable upgrade I’ve ever made and certainly the best USB cable I’ve tried among many, including AudioQuest Coffee and another well respected cable line, whom I am a dealer for!!
The line I am a dealer for is easily the best of the rest, but even connecting both ends to my iMac, your cable is better sounding and not by a small margin. Good for you….Simple is good….

“They already sounded cleaner and have a darker background when new.” — Guang
The sound does develop over time. They take more than 60 burn-in hours or so to sound significantly better than the stock cables (you mentioned more than that on your website); however, they already sounded cleaner and have a darker background when new.
Sometimes I wonder whether my ears, brain or the cable is the one that needs to be burned-in. By comparing the Audiocadabra and the stock cable side by side after several weeks I am pretty sure burn-in does result larger differences.

“Wonderful product, highly recommendable.” — Dimitrios
The cable arrived, thank you for the bullet proof packaging. It is wonderful to handle, and most of all sounds impressive right out of the box. While burning it in, i definitely can hear some further improvement in sound quality after 3 days.
Wonderful product, highly recommendable.

“Warmish, reasonably transparent, fluid like bit of tubes, relaxed without any kind of fatigue.” — Himadri
The Ultimus 3 is as you described better than the version 2 in every respect , by a small margin but still noticeable, which is not easy as version 2 itself is very good already indeed.
I am thinking whether you would come up with a short USB cable offer like the 20 cm Regen Link from curious cable. You know iFi had come up with a whole host of add-on’s and each release has its own incremental benefit to the SQ of CAS. I recently added iFi’s iGalvanic 3.0 upstream to my iFi iUSB3. Now my chain of gears became: Mac mini–> Ultimus 2–> iGalvanic 3 –> curious regen link –> iUSB3.0 –> Ultimus 3 —> DAC. In my previous A-B comaprison, Ultimus 2 beats Curious cable in musicality and life-like-ness. So am thinking to add another one to replace the regen link. However, the length of 50cm seems to be excessive (the always-desires-to-optimize mind resisting the idea to add longer run than regen link), and am struggling now.
I believe a lot of CAS players are like myself, and if you would offer such 20 cm short cable option for the single-headed version, of course at a slightly lower price-point to sweeten it, this could open up another market segment.
Please see the attached…. a bit messy, and showing your competitor Regen link in conspicuous yellow, so maybe I should send u the photo after getting your short cable offer 🙂
The one to the bottom of the pic is Ultimus 3, in Peter’s extreme shield mod v2 :-D. I used a wider wire gauze this time so as to not “restrict” the music flow…
The far end shows Mac mini feeding to igalvanic 3 via ultimus 2 split head, fed by lps.
Look forward to seeing the 20 cm offer on your site!
Just sharing my current thoughts…
Thanks again for making great USB cables at such competitive cost!

“Cable sounds marvellous with my Wavelength Brick USB DAC.” — Patrick
As promised here is my testimonial. I did not find a way on your web site to post it on line.
I purchased two USB cables from Audiocadabra, uncertain as to whether a dual headed cable would be required for my DAC and intending to sell which ever cable I did not require. I received the cables within a short time of placing my order. The manufacturing quality is excellent and I love the minimalist design. Separation of the power conduit from the data conduit makes a lot of sense to me. The single headed cable sounds marvellous with my Wavelength Brick USB DAC. I will be keeping both of these cables as they represent fantastic value and I know I will use both over the coming years.

“At the price it’s a steal!” — Lau
The Ultimus II USB cable is just fabulous. Immensely musical, close to real presentation, high and low ends are well balanced and textured. At the price it’s a steal! I have a strong bias for silver wire, split head design and twisted wire without heavy shielding, and your offer is exactly that at such an attractive cost. I wouldn’t say it beats every other USB cable, coz I have not listened to every one. However it’s a much better deal than the WW Starlight platinum in terms of communication of emotions and ease of listening.
Thank you for making such a great USB cable, and I wish you every success as you guys deserve it!

“Definitely a keeper, and a wonderful surprise at this price point.” — Brad
I received my Optimus Dual-Headed USB cable from you today, and couldn’t be happier. Straight away it is sounding relaxed and detailed with my various setups. Definitely a keeper, and a wonderful surprise at this price point.
Here’s a picture of your cable in my office headphone station – BTW, the cable works very well with iFi Audio products. The setup in the photo is with a NOS DAC that plays 16/44kHz. I’ve also used the cable with my iFi Audio Micro iDSD, which plays PCM to 768kHZ and DSD512.
Thank you very much once again.

“The Optimus is simply very good. I must say, well done!” — Ernst
I am using your USB cable now for about a month and it is feeding my exD USB to SDIF converter from a JCAT USB card. The exD converter is feeding the SDIF input of one of my dCS Elgar Plus DACs. I am very convinced by the quality and sound of your cable and I have never felt the need to change it out for any other cable. The USB cable is simply producing a very clean and transparent sound and I never felt the need to switch to one of my dearer USB cables, as the Optimus is simply very good. I must say, well done!

“Accurate mids and non-fatiguing highs. Your cable preserves and enhances that. Once again, solid core copper can’t be beat.” — Mark
It turns out it was the input jacks on my Sennheiser. After a few struggles to plug in and unplug them, it got a lot easier. I think they just needed to be loosened up a bit. Now I can swap them fine now. So the jacks are no longer an issue, and I like that they are color coded red, with visible stickers instead of the terrible hard to see labeling of stock cable. I did another side by side test this way and I think I hear more clarity, but I’m going to burn them in with pink noise for a few days and test them again.
After 100 hours break in, the sound did improve. They definitely are worth keeping, and I’ll be mentioning them regularly on Head-Fi and on pro audio (studio / recording) forums. The HD650 are popular with us engineer folks due to their accurate mids and non-fatiguing highs. Your cable preserves and enhances that. Once again, solid core copper can’t be beat.
I have no photos for you as it’s just on the output of a firewire all in one box (mic preamps, MIDI, etc.) connected to a computer. Really nothing to see. I’m pro audio vs. audiophile, it’s a boring looking setup.
But I will be name dropping Audiocadabra (I already have twice in the last two days) in various forums. I’m not alone in being a “solid core copper” advocate for wire.

“Your cable clears a straight path to the live music.” — Ian
Great USB cable! Your cable first try knocks it out of the park!!!
First update:
USB Cable sounds amazing—20 hours burn in.
Beautiful, clear, quiet, organic so easy to listen to like in as listening to Doug Macleod Black nights.
Second update:
Your double headed cable is beautiful and it sounds clear enjoyable. Going on thirty hours in my system getting better by the hour.
We bought our Oppo 105, MacBook Pro and your double headed cable up to our new house in Cloverdale Ca. North of San Francisco. My system up there is also a Onyko Tz-NR838 Naim streamer and two Elac B6 speakers and their center channel speaker. Wow omg!
What a difference from in ceiling noble fidelity speakers. To the Tri stereo set up at ear level. You are inside the music. Your cable clears a straight path to the live music. I’m so impressed at you and your team!
Your Cable is so amazing! Thank you for making us very happy. It’s like listening to air with beautiful music mix in. I’m hooked! The cables sound so natural, thank you!

“It allows the music to pass through without restriction, the sound I get is very open and big-sounding.” — Edmund
I have been enjoying the cable very much, for a few reasons:
I use the SoTM PCIe USB3 card for the digital audio, and an iFi USB power for the power leg. With the dual-head cable, I reduce the need for 1 more USB cable. i.e. I plug the data head into the SoTM card, and the power leg into the iFi USB device. I believe this contributes to the improvement in sound quality (less cables is better)
After run-in, I no longer can hear any sound signature of the USB cable, i.e. it sounds very transparent to me. It allows the music to pass through without restriction, the sound I get is very open and big-sounding. This is no small praise as I was previously using a Acoustic Revive 1.0 PLS USB cable which is almost 3x more expensive.
I would have no hesitations recommending for people looking for a value-priced, but certainly not value-performance (performance is better than what one would expect from a value-priced product), dual-head USB cable. As mentioned, it would be good to offer customers an option of the MKI or MKII cable.
By the way my wife likes your name. 🙂

“I’m actually rather shocked.” — Peter
Just letting you know that Achtung Audio Pure Solid Silver Phono RCA Interconnect Cables from eBay was the cables I’ve been using and also before that Audioquest Sydney.
Rather surprised that the your cable sounded much better than those two. I suppose having more strand of silver cores doesn’t necessarily mean better sound? I’m actually rather shocked.
I really do love your cables. I will probably end up upgrading my brothers system as well, but he isn’t much of audiofreak as I am so, will see. I will get back to you in two weeks. Time to save up my allowances for the Audiocadabra Ultimus Ultra Solid-Core Silver Speaker Cables.

“Your cables perform brilliantly and at a price that defines the word ‘bargain’. Well done!” — Karl
I had come upon your website rather randomly and purchased your product on impulse, so I can’t honestly say that I had any expectations at all. I can say however, that the impulse was one that has been rewarded. Your cables perform brilliantly and at a price that defines the word ‘bargain’. Well done!
One thing I might change, would be to clarify by word or image that the cable pairs are interleaved, rather than separate runs. That wasn’t obvious to me, but frankly, I was happy to buy another set to suit my monoblock amps. How can one regret having spare cables of such quality?

“I switched briefly to my old cables. Yuk! Congratulations on bringing something to market that offers such good value for money.” — Adrian
I previously ran signal from my laptop (JRiver) via wi-fi to a media player and from there via toslink/optical cable to my Cary DAC100t. It sounded good.
I also tried running standard (printer cable) usb from my laptop to the DAC. It did not sound good. Grainy, harsh.
I now run Optimus from the laptop to the DAC. It sounded better than either straight away, though it was quite hard. There was more detail, the bass less muddy or woolly, which is what I experienced with the optical cable.
I had read other reviews and opinions (which is why I chose Audiocadabra over Starlight- as recommended by one of your customers).
Reviews indicated a long break- in time and I concur. So I have let it play and play and it has certainly improved- less hard and sibilant, smoother and more tonally balanced with a neutral, clear, open and coherent (tight) delivery.
I reckon it was money very well spent. It is unfortunate that one cannot audition your cables first (not in South Africa) as my next purchase will be two pairs of balanced cables. Those I definitely need to hear before I buy.
My system: laptop> Cary DAC 100t. Modwright LS100 preamp> Hypex Ncore400 monoblocks> Eminent Technology LFT8b speakers and B&W ASW700 subwoofer. Acoustic panels.
Present interconnects are Cardas pro audio range (not fancy) with Audiomica Dolomit speaker cable. The Optimus goes to the Cary Audio DAC100t, then the Modwright etc etc as per my earlier mail. Oh, the AVR is a Marantz 6005.
I’m not a good photographer but my setup looks lovely (to my eyes) with the backlit acoustic panels in my room. I’m a lousy photographer…. I think I’ll listen to some music instead.
I switched briefly to my old cables. Yuk! Congratulations on bringing something to market that offers such good value for money. It really is a cable that just gets out of the way- doesn’t interfere or add colouration to the music. Quiet, clear, open and transparent.

“All my life I believed that cables were a gimmick and that they don’t make any difference!” — Shyam
Since my initiation into the audio world, 05 decades ago, I always thought that ordinary wires were good enough for good sound. All my life I believed that cables were a gimmick and that they don’t make any difference! This old perception went for a toss, when I came across audio cables created by Audiocadabra. Never have I experienced such exotic sound. The entire spectrum heard through dedicated headphones or amplifiers is simply mind blowing.
I compared them with audio cables, available locally—Indian, Chinese or Taiwanese, whose sound did not have a pure and transparent sound as the ones handcrafted by Audiocadabra. I now use these cables exclusively in my audio demo room in Mahim.
After your last visit, which was one of the most astonishing in my experience, my laptop coupled with a well-known DAC and your cables resulted in “hearing is believing” maxim.
I wish Audiocadabra all the best in this wonderful creation. I look forward to trying their higher end premium cables. I highly recommend this brand!

“You would not think that for such a small investment, you could get that much of a sound difference from your system.” — Duvall
I bought the dual head USB cable. I can’t believe the changes it made in my system. I did have to buy a 5V Charger because when I unhook the power side of the USB cable, I would get distortion in the sound. But even when you have both heads hooked up to the CPU it’s still is a major change in sound quality and when I hooked up the charger to the power side of the cable it took it to another level, much more open sound. You would not think that for such a small investment, you could get that much of a sound difference from your system. I love this Cable.

The last three weeks I have listened to your cables in the set with the Unison Research Triode 25 tube amplifier and Blumenhofer Fun 13 loudspeakers. They are flexible. The spades I tightened with pliers. Because the Blumenhofers are more suitable for banana connectors.
First impression; clear, clean sound, with good timing and details.
After the first week I listened better.
Pros:
– much detail
– good timing and speed
– clear sound
In the price category you sell the cable, this is a very good product.

“I am getting a feeling that the Audiocadabra USB cable has more in the treble than the others I’ve used.” — Nikhil
Just received the Audiocadabra cables. They look great! Have placed the Audiocadabra Optimus IC between the DAC and Pre. Let’s see what the sound is like!
I decided to put them both in the rig so that they can both burn in at the same time. As soon as I put them in the sound immediately was “lit up” or etched – any silver in the wire? But as the evening progressed the edge wore off leaving the highs a little more pronounced. My thinking is that the bass will open up more with more burn in. It’s there but a little recessed right now.
My wife described the initial sound as very “hifi” – slightly harsh with a little glare. We got in about 5-6 hours last night as we let the cables burn in over dinner. They did mellow down a bit after a few hours. As I type this, the harshness is gone but some glare is still there… The connectors are solid and grip the RCA mounts very well. The cable has the minimal Kimber Kable look. Very different from the thick cables from other suppliers.
At this point, I have to say I like the Audiocadabra Optimus Dual-Headed USB cable over the Pure Silver USB by Lavrycable from Ukraine. Separating the power wire does help clear up the sound quite a bit. The Lavrycable was with the 5V wire disconnected. I am getting a feeling that the Audiocadabra USB cable has more in the treble than the others I’ve used – maybe giving the impression of more detail. A little more listening time is needed before arriving at any more conclusions. But they do sound very nice and I have enjoyed having them in my setup so far.
Post Burn-in Impressions
As you know it took me some time to get these cables in my chain with the other cables I had in for review. This was not a knock on the cables but just the fact that I had got them later so needed to complete my listening to the cables I already had in hand. As luck would have it, travel around Christmas and some long work out of town in January pushed back the time to when I could get some time to listen to these cables.
Optimus Dual-Headed USB Cable
This cable has been in my setup the most – since October I believe. I had been using your cable which you had given me earlier. The difference between the cable I had made with the 5V completely eliminated and the Optimus Dual Cable was weight. Changing between the two showed the earlier cable to sound a little thin in general. With the Optimus Dual Head Cable in the chain there was more meat to the sound. The bass extension filled out the mids and lower end. In addition the higher frequencies got more solidity. This is not a subtle change but is easily noticeable the minute you place this cable in the chain.
Considering the significant more outlay that other manufacturers are charging for a similar cable this has to be one of the best value propositions out there. The cables do suffer in the looks department but considering the braided bare wire is part of the design one can live with them. Perhaps a little more beef near the connectors might give one more confidence. But looks aside these cables will outdo most cables. I preferred these over a USB cable from Lavry Cable from Estonia which are designed with a different philosophy.
Optimus Analog Cables
These were the cables that I struggled the most with – I don’t know if it was the Amphenol connectors or just simply the overall bare wire design. I had dismissed these cables the minute I got them. I had wanted to simply hook these up on my setup and dismiss them after my ears would confirm what my mind had already made up.
I had another cable in my rig which I was more interested in listening to quite frankly. So when I did get some time I wistfully removed the existing cable and connected the Optimus Analog ICs. Without burn in they were slightly bright or lit up a touch. But apart from that … not too bad. This was not the plan. I was supposed to hear them sound bad and send them back. Instead here were these cables making a pretty good case for themselves in spite of my bias against them. Still not having the patience to hear them through I placed the earlier cables back in.
With Christmas and January passing, I took the time to let these cables sit in my rig. For about a month and a few days the cables got a little bit of burn in going. With time the cables began to settle in and in time most of the early glare wore off. I began to notice that the cables were actually beginning to sound pretty good. Placed between my DAC and Preamp these sounded as good as the cables I had liked from another supplier. The cables had very good control over the sound. My favorite instrument to evaluate a cable is the upright bass. With your cable the sound of the strings had texture and a springiness that conveyed the pressure the bassist applied to the strings. The piano is another instrument that can be difficult to get right. These cables tightened up the tone of the piano on Piano Improvisations by Ola Gjeilo.
People considering these cables should allow for significant burn in as they tend to be lit up initially. With gradual burn in the sound smoothens and opens out. I have them in my setup for about 300 plus hours now. When you take them out they tend to need a little time to settle in when you put them back in. In my setup I would guess this was about 20 hours.
These are great cables and I am glad I gave them a chance despite my reservations. The price level is absolutely a steal when compared to many fancy offerings out there. I have no doubt that these cables will surprise many with their quality.
