USB Cable Comparison Audience / Cardas / Purist / Stealth / Wireworld

A Continuation of the USB Cable Comparison   Purist / Stealth / Wireworld

PHASE 2.1

The Purist 30th Anniversary and the Stealth USB cables arrived a week after the SR went into the system.

Changes from the Phase 1 comparison:

- Sonore Signature Rendu SE replaced the ultraRendu

- Schiit Yggdrasil DAC for the comparison of the Purist, Stealth, and Wireworld cables.

- Denafrips Terminator DAC for a second comparison of the Purist and Stealth cables.

The Cable Co. was kind enough to extend the first cable loan until I could get a feel for these three cables before sending the Wireworld (WW) back.

Second Phase Ranking and Results:

1st: Stealth USB

2nd: Purist 30th Anniversary USB

3rd: Wireworld Platinum Starlight 7 USB 2.0

It was clear with the Stealth in the system, that it was superior to the WW across the board. The Stealth basically brought more of everything the WW does well, as well as improving upon the qualities that the Audience and Purist Ultimate cables do well.

The purity, refinement, delicacy, detail retrieval, micro-dynamics/detail, venue insight I loved about the WW shifted in favor of the Stealth. The Stealth offered more reverb , better decay and much better bass and sheer energy. It made the WW sound ’less’ natural in direct comparison.

The differences when taken as a whole delivered greater emotion, realism, energy, insight and musical sensuality offering me a higher level of engagement, appreciation and emotional connection to the music.

With the Stealth in the clear lead, and some urgency to get the first four cables shipped back to The Cable Co., I did a quick comparison between the Purist 30th Anniversary and the WW. I preferred the Purist over the WW, but not by the same margin as the Stealth or for the same reasons. I will elaborate on the Purist’s performance which should allow readers to come to their own conclusions of the strengths and performance and sound signature of the WW and the Purist.

I’ll share the final comparison between the Stealth and Purist in my next post. Likely in a day or two.

What follows is a comparison between the Purist 30th Anniversary USB cable and the Stealth USB cable. This comparison, with it's focus on the Stealth (it's strengths and performance) as the first place finisher, also applies versus the Wireworld and the Audience cables.

My initial take / read on the Purist 30th Anniversary (P30) after it was added into my system was that it was better 'out of the box' than the Purist Ultimate (which is a step below in the Purist line-up).

The P30, however, needed more run-in time before I felt it had stabilized (this may have been relative to how 'broken-in' it was from the lending program). Highlighting this in case you go with the P30. You may have to give it some time.

It is a warmer and softer sounding cable, than the Stealth, and it's rounder and fuller signature is addicting and enjoyable. It is more forward with vocals. It is also superior to the Purist Ultimate across the board and minimizes the Ultimate's weaknesses. However, both have a very similar 'house sound' to them. The P30 is better, but it comes at a 60% premium over the Ultimate.

The Purist highlights or accentuates the main / primary focus of a music passage or recording section. It is there, fully bloomed, like a close up photograph of a flower, with the other details, as you pan further out and further in, lightly to more faded out and hazier. The Stealth balances that primary focus with all of the other musical information around that main section, without marginalizing it. It shows the flower along with more of the parts and layers and makeup of the flower as well as the stem / leaves / and plant that it is part of. It conveys a whole and comes across more natural and real while doing so. All the while maintaining it's grip and delivery of that 'main section / musical passage.'

The P30 does not resolve micro detail as well as the Stealth. This was interesting, because I noticed the micro-details with the P30, as in 'hey, there it is.' However, when I first listened to the same via the Stealth I missed those 'hey there-they-are details' initially. I was fairly sure that wasn't the case and in the process of figuring it out, I learned a very important lesson.

The micro-detail, more importantly the micro-micro detail, was very much present with the Stealth. It was conveyed as whole music, rather than a 'break' or 'hey there it is' piece of information / 'interruption' (as in "there is music there" vs a piece of information) which is why it was easier to miss. 

Audiophiles talk about that 'lost in the music' state...I think this helps convey this point. The Stealth was so good at this (this level of resolution and clarity) that the information did not stand out as an 'anomaly' (noticeable, if you may) but rather as a continuation of, and inherent part of the music.

I found the Stealth to have better timing, and tighter control than the P30.

Where the Stealth really stands out (vs the other cables) is in the level and amount of musical energy and pressure conveyed, the control and delivery of bass and the naturalness in how it conveys musical tension.

It manages to do this while being delicate and refined, and handles musical layering better than the other cables.

As I review my notes, I cannot see an area of music or 'audiophile descriptor' or a specific track segment that it was bettered in.

There is just 'MORE' to the music. A Greater Whole. I naturally preferred it and kept wanting this cable to go back into my system.

IT, I SHOULD SAY MY SYSTEM WITH THE STEALTH IN IT, is rendering music beautifully with a level of emotional engagement and realism I am thoroughly enjoying. Getting lost is now easy.

I ordered the Stealth USB in a 1M length from The Cable Company. It went in system on the 15th of Nov. and is nearly broken in.

This is one of the better reviews/evaluations or whatever you want to call it of a cable or component that I've read in quite some time. Not everybody can convey their thoughts and feelings into words and I think you've done that exceptionally well here. I've experienced something similar lately where you get "lost in the music state" as you put it and you just want to stay there. It's amazing that with just one change of either a tube or a cable you can lose it. My problem is I'm constantly wanting to try new things instead of just being content with what is a musically and emotionally satisfying experience. That emotionally engaging experience is hard to explain to people and I think what separates those who just want to put a system together and "hear music" and those who get lost in the music. Very well done. 

Here is one example of a track I used to assess the cables. It isn’t a typical audiophile choice, but it served a number of purposes for my evaluation.

The differences between the cables are illustrative and reflective of the final outcomes.

’Giorgio by Moroder’ on Random Access Memories by Daft Punk

There is a long [1:50 min:sec] segment of Giovanni ’Giorgio’ Moroder speaking. He’s speaking at a venue (overlaid in the recording studio) with venue information, background voices/music/sounds, an electronic arpeggio beat and house music.

I like evaluating components / my system with voice segments. This particular track offers layered and very different types of information, essentially at the same time or very closely together. The highlight for me is Girogio’s spoken English with a slight accent.

A series of clicks are introduced into the track at the 1:30 mark. The track transitions to full on synth beat after the 1:52 mark. This evaluation was focused through the 2:00 minute mark.

The comparison resulted in the following rank order: Stealth > Purist 30th > Wireworld.

P30: The musical line lightly powers over his voice and there is a slight haze with less micro-detail vs the Stealth. There is slightly less background information when the track opens (the first few seconds). It’s presentation is superior to the WW and it moves closer to the Stealth in fullness and the energy conveyed (vs the WW). I found it a smidge slower and with slightly rounder definition than the Stealth.

WW: The bass is rounder than both the Stealth and P30. There is more movement to the clicks in the soundstage (with the P30 and Stealth - the clicks are more fixed positionally) and they are not delivered with the solidity and body of the Stealth. The WW sounds ’thinner’ and less palpable than the Stealth. The voice also comes across slightly faster / ’rushed’ perhaps. The WW did very well with background and venue detail and information.

The WW presentation is not as musically engaging. It doesn’t sound as real...in my notes, I label the sound with respect to the other two cables as ’artificial sounding’ for this specific segment.

Stealth: The conversation sounds very real, to my ears. The clarity/transparency delivers superior voice vs. the other two cables. The inflections, the breaks and starts, the breathing and subtleties of his voice and accent are clearer and more real. There is more body and weight to the voice, which also holds up at lower volumes (vs the other cables).

As a very specific example within this track segment and the voice part of it: the ’trill’ in the ’R’ in when he says his own name ’Giorgio’ at ~1:50 is expressed better.

The venue information and background voices and noises are presented better than the other cables. The bass line is both tighter and more musical throughout and doesn’t overpower Giorgio’s voice. The timing or pace of the music is the best among these cables. It has the more impactful and musically engaging presentation among these three cables.

The Stealth puts me more ’There’ and with more of an ’It’ or ’Wow’ factor, when I compare these cables. The Purist 30th Anniversary is a close second. The WW a more distant third, with this specific track segment.

Most companies recommend 1.5 meters for USB. I know Wireworld suggests 1.5 meters as the optimal length. Does Stealth suggest 1.5 meters as optimal? I noticed that the WW was 1 meter, do you think the results would differ if the WW was 1.5 meters?
