USB cable shootout: 8 cables tested

I am amazed by Signal project Andromeda usb cable, even better then Atlantis , and much better then AAI Estremo, comparing side by side. Even the owner of Estremo said Atlantis is better then Pi audio Ultimate and and better then AAI Estremo, then Andromeda usb came and beated all of of them in my system by bid margin, sooo musical, more depth, more realistic, more holographic, more analog sounding, unbelievable what this cable does.

@Zappadaddy What does “better” mean or entail for you? Not much to work with in your statement without specifics as to what makes “better” for you about one cable vs. another.

Tonal effect: cool, neutral, warm? Between what and what is the cable being used?

Out of the box, the Estremo seems fairly accurate in some respects (drums) and bright in a digital sort of way for the rest, clear and clean, fast, good soundstage breadth and depth. More than that, and how that evolves is tbd.

Is there any reason for a USB cable rated over 2.0?

Was a high quality USB cable like something from the belkin pro series tested?

I should know better than to question the value of expensive esoteric cables on a cable forum but I am more them skeptical.

More liquid, wider scene, holographic, no agressivity at all without loosing high resolution and highs, full body with real instrument tembre, the best usb cable I have ever heard. We tested Estremo against this Atlantis, no contest in favour of Atlantis, the owner of Estremo said in my setup Atlantis is better, high praise from guy who has all top models of AAI, he is AAI freak. Then Andromeda usb came even better, I love Signal projects cables. I am awaiting more of them, rca and power cables.
 
Hi, everyone

I wanted to ask you guys: would it be wise for me to change my Shunyata Research Gamma USB to a David Laboga Emerald Mk2 USB?

Thanks in advance
 
Any experience on XACT Audio Phantom USB Cable?
 
...I have an AAI Estremo USB cable probably arriving timorrow for a 14 day trial.

Turned out the Estremo USB in my system was at the time the best I'd heard. Very good in all respects but one: it sounded (digitally) bright or, to put it another way, pitch elevated. Especially evident with piano (often electric sounding) and vibraphone.

Today, I received a used (demo) Signal Projects Statement Andromeda USB. Out of the box, this is a stunningly superior cable, in my experience comparable to the ~4K Shunyata Research Omega X. Except the Andromeda has a sense of presence, while the Omega was more laid back, distant, better for reading to than an active listening session. SP wrote me that the Andromeda is very warm. I don't like very warm - just a little bit - but so far it's far from that. Look forward to seeing what happens as it settles in.

How is the Andromeda getting along in your system? I have the original Omega usb and while very good, I too find it a little distant and laid back.

Exactly what I found with the Omega-X. I like a touch of warmth, and didn’t find the Andromeda satisfied that need, at least in my system. If you like (modestly) neutral, then it’s a really good choice. And all the more so at the price I’m about to put it it up for sale at (in the ball park of many of the mid-level cables that have been discussed here). PM if interested.

If I'm reading you correctly the Andromeda is a little on the colder side of neutral? If so I find that surprising considering the conductors are a mix of copper and gold

Yes, it was advertised to me as warm, even very warm by Signal Projects, although the latter didn’t make sense, I’m burning in a SR SRX at the moment, or more specifically one of its tuning modules, but I’ll give the Andromeda another try to be sure.
 
Results:

Albedo USB
Length: 153cm
UK price: Oops, I forgot to ask!
View attachment 116694

Brown cloth (?) wrapped floppy cable. It’s bass is OK, not tight though, but slightly boomy. Its not as clear or pure as say the Sinope. Also its not quite as alive as some of the others, it had a very slight dull and slow feeling to it. Unfortunately it doesn’t really excite you listening to it. Upper end detail was OK but again nothing exceptional.

David Laboga Emerald Mk2
Length: 107cm
UK price: around £500
NB no 5v power cable with this demo cable
View attachment 116695
This is one of the first cables I tested, and the cheapest in this group test. So that means the worst performer right? Absolutely not, this cable is incredibly impressive!
It has a naturalness that some others here would die for. And the BASS! Punchy and tight without boominess. Fantastic! And it goes REALLY deep, I would say in fact, the best in this group. Impressive stuff.
Listening to "Time" from Pink Floyd was the first time I had heard the underlying heartbeat sounds at around 1.50-2.20 really punch out and add a dramatic tension, basically engaging another sense into the experience. It felt like I was being kicked in the musical maracas each time, and I loved it!
It passes my "toe tapping test" easily, you just enjoy listening to music via this cable.
However its not as pacy as the Muon say, and the upper registers aren't as emphasised. The attack on strummed guitar strings is fine and has good air/ 3D imaging
This cable definitely gets my HIDDEN GEM AWARD, it competes with all the others here, but if you are on a budget in any way, just get this one! You’ll love it.


FTA Sinope
Length: 136cm
UK price: £1395
View attachment 116696
In some ways, this is the one to beat. This cable is held in high regard and rightly so, because it sounds great! It has a slightly more unusual profile, being quite wide and flat, but plug this baby in and it just works to produce great sound. Slightly fuzzier than the Sablon, maybe a fraction flat, and not as impressive 3d picture overall. It does have a good naturalness and good rhythm to it, it sounds balanced across the whole frequency range. Having a think about it afterwards, I think the top end is quite smooth which makes the cable very listenable to. It also means attack on say strummed guitar strings is less than others. The overall airiness is also not quite as good as some others. I did find it clearer, more musical and better stereo picture/projection than the Infigo.
The only real downside to this cable is the bass is very slightly lacking in punch in comparison to others

Infigo USB
Length: 110cm
UK price: approx £1000 (depends on offers and import duties)
View attachment 116697
A bit more bass than the Sinope but it wasn’t tight, having a slight boominess to it in comparison. The top end has a bit of well… “bite”, “harsh” or “edge” are too strong of words to use, but maybe bright is closer. Also the mid range is slightly less pronounced, the cable give me a clear picture of what its doing in bass and upper treble but less in the middle. If you have a soft sounding system this is probably what you need to balance it. Slightly more reserved in presentation than the Beethoven. Overall close to the Sinope, but the Sinope would have the victory.

Network Acoustics Muon2
Length: 150cm
UK price: £1395 (overseas will be less as no UK VAT)
View attachment 116698
When I was arranging the demo cable, I got chatting to Rob the cable’s designer. This is the new Muon2 version of his cable, and I have the privilege of being one of the first to hear it. Apart from the general form factor of being 2 thin and 1 thicker cables, everything is new about this cable, new conductor, new assembly techniques, new connectors, the works. I haven’t heard the original, but what does the new and improved version sound like?
Well out of this group, I would say this is the clarity king. Music is just clear as a bell. It has a bit more bass than the Sinope, although it could do with being a bit tighter. It has more detail, purity and clarity than the Sinope too. It feels pacier than it too, my listening notes say "more alive". Imaging is good, attack is nice, treble is more pronounced than the Sinope. More stereo imaging than the Infigo

Sablon Audio Evo USB
Length: 122cm
UK price: £1000 (overseas will be less as no UK VAT)
View attachment 116699
Good bass that goes deep, and more attack than the others on leading edge notes like guitar strums. Not quite as airy as some others though. As with the Infigo, bass and treble seem pronounced, but the mid range plays a secondary role somewhat. Imaging is OK to good, and quite musical too. Pink Floyds Time guitar piece at 4.00-4.20 can sound a bit edgy with this cable though

Skogrand Beethoven
Length: 210cm
UK price:£6000+
View attachment 116700
Yes I’m pretty sure that price is right. For this, you get an impressively chunky and substantial feeling, silk wrapped cable. So what does it sound like? It’s a richer, fuller sounding cable with good air to it. The bass is very good with a nice punch to it
Overall, its a good cable and fits in easily with these other cables, without surpassing them. If you factor in the cost though, it represents very poor value for money, and I couldn’t recommend it at this price.

Tara Labs Master
Length:
UK price: £3000
So the final cable is a bit of an outlier as its considerably more expensive than the rest (excluding the overpriced Skogrand). So to be fair to the rest, its a little bit of an apples to oranges comparison. It is also unusual in that it has a special grounding box with it. You connect a small supplied cable from the end of the USB cable to the box, and also attach a ground wire from the chassis of the source to this ground box as well.
It was also the last one I got my hands on, so when you read comparisons above, they dont include this one.
But this is whatsbestforum, so whats best out of all these cables? Answer, this one! Maybe not a step up over the rest, but at least a good half a step. It wasn’t hard to realise this one was the winner, whereas with other cables, they were pretty close. (Again for the number people, I would say around 15%)
This cable projects music out into the room unlike anything else here. The bass is plentiful and oh so tight and punchy. Have "Devil Inside" going at high volume and you really feel those intro bass punches in your chest. But its not boomy. I find the recording of Pearl Jam's Alive can be bass saturated in my system.
But no, it was the USB cable all along! With the Tara its perfectly listenable for the first time. Have the last part of "The Chain" on high volume, and after the bass riff, Buckingham's guitar can sound a bit shrill and biting. But again, not with the Tara. But this isnt due to it being soft at the top, not a bit of it, its just clear and free of harshness.
This cable is beautifully clear and the instruments are clearly separated, the air is very good, a wonderful open sound. I wondered at one point if it was a fraction slow sounding, but after further listening decided it was spot on (maybe just it was warming up in my system in retrospect). The stereo picture was excellent. It gets my OUTRIGHT PERFORMANCE AWARD and convincingly so.
However finally, there is one small problem with the Tara Labs Master. It is only their mid range cable, it has a big brother, the Grand Master cable at £5k.... Eeeek!

Conclusions:
OK its pretty clear which was my favourite, but how would I rank the rest? Well I think the best for you will depend on the sound of your system and what you like. For my preferences and my system, despite their weaknesses in various areas, the ones I personally kept coming back to are the Sinope and the Emerald. I just found them particularly musical and enjoyable, which to my mind is the essence of what listening to music is about.
As to the others, if you like attack on the leading edge of your guitars, or your system is soft sounding and needs more bite, get the Sablon. If you want clarity and purity, get the Muon2. If you fancy the Sinope but its a bit too pricey for you, look at the similar Infigo. Horses for courses.

And finally, many thanks to the reps/manufacturers/distributors for the loan of these cables to make this group test possible!
What an excellent write-up! TY. What an excellent write-up! Thank you.

My only note on these fantastic cables, and which brand/model will be preffered globally, is that the result will be somewhat system-dependent. Also, really enjoy the Sinope with Lampizator DAC as they were voiced together. While we use other DACs in our listening lab to ensure we can voice our loudspeakers across a spectrum of qualities, in many cases we chage USB cables to more closely match the overall tone, detail, and dimensionality we are seeking.

Yes, it’s completely normal that the same USB cable behaves differently in different systems. A cable is not “warm” or “not warm” on its own — its effect depends on the specific components it’s connected to.


A USB cable mainly influences noise, jitter, and signal integrity between the source and the DAC. Different DACs, servers, and power supplies respond to these factors in different ways.


In a very transparent system like Aries Cerat Kassandra, the Andromeda can show its musical, smooth and organic character. In another system with a different USB implementation, clocks, or power design, it may sound more neutral simply because the components react differently.


So both impressions are valid — a USB cable isn’t a universal “tone,” but an interaction with the system it’s used in.




My personal experience:
In my system, the Andromeda delivers an extremely organic and natural presentation with a very open, three-dimensional soundstage. It has high resolution, but never sounds digital or artificially “coloured” — the detail comes across effortlessly and without edge. Instead of shifting the tonal balance, it simply lets the system breathe and flow more freely.


For me, it genuinely elevated the whole system to a different level.
