After spending a few weeks with both the Shunyata Omega-X and the Synergistic Research Galileo Discovery USB cables, both in the $3K range, here's what I found:
Galileo Discovery (Gold module). -- a little laid back, easy listening in the best of senses, clear, articulate, tight, clean, smooth, balanced. It comes with the Gold and Master modules. So far I've found the Gold does everything a touch better.
Omega-X — Swings!, alive, expansive, clear, detailed, a little on the neutral side, in many ways an ideal sound
Both are clearly a-level-above cables. I hope to get another shot at the Omega-X to see if I can coax my system a smidgeon into the warm side with it. I had started to move there when I had to return it.
To update my previous post (#422), I spent 300+ hours with the Infigo cable, including 100 before it arrived, thanks to CalvinJ. Along with that, I got another round with the Omega-X, and also pulled in my CAD II-R, which had been sitting around during the previous testing. While I of course listened to a lot of music with each, when it came down to a final comparison, there were three, all live audio performances (FLAC files), that were used for final comparison. I list their YouTube links below.
Setup: All the cables were run from a Samsung 850 Pro SSD in an Innatek case to a highly modified, digital-only Oppo 203. On the source end was an Audioquest Jitterbug FMJ, and at the Oppo end there was a B to A adapter. I’ve yet to find a USB cable whose sound doesn’t benefit substantially from the FMJ, while I’ve found the adapter (from the SF cable co., as I recall), has negligible effect on sound quality. Likewise, I’ve found the 850 Pro to be the best sounding SSD of the several later Samsungs and other brands I’ve tried. See my Sig for the rest.
Here's how the cables fared in my system:
- Shunyata Research Omega-X: Clean, clear, fast, rhythmic, quiet! (hearing space between notes), balanced, good sound stage, as accurate pitch as I've ever heard, foot tapping. As I wrote earlier, it swings! Drawback: emotionally laid back, not quite present, sometimes more than a little (e.g., famous Talking Heads concert). For me, frustratingly not quite satisfying, all the more so at the price ($3800 less Cable Co benes).
- CAD II-R: A lot of the good, relaxed characteristics of the Omega-X, but not as clean and clear, as one might expect of a mid-priced cable ($1500). A bit more voiced to the lower end than the Omega, with the perspective a little back from the speakers. Its touch of warmth makes it very listenable for me. A few months back, I spent time with the Sablon Evo, and remember hearing a bit more details with it vs. the CAD, but also its balance was tilted upward, so not as relaxed as the CAD.
- Infigo: Present, dynamic, not quite as clear as the CAD, but an overall good performer with the balance a little more to the upper half of the register, though (from memory) less so than the Sablon, and with a bit of warmth. A reasonably capable cable for the price ($1200). Be a an interesting comparison with the similarly priced Sablon.
- WyWires Diamond: I mention this former cable of mine because I use the excellent WW Diamond PCs and ICs almost everywhere, but Alex's USB cable, while definitely better than the FTA Callisto, is not up to his others, nor to the CAD, Galileo or Omega.
Right now, I'm not sure what I'm going to do. The Omega has created a standard that puts the mid price level cables in a different perspective. Given a few changes to my AC cabling/adapters since the earlier review, I wish I had access to the Synergistic Research Galileo Discovery again, and even a moment with their top-of-the-line SRX (not that I can afford it retail ($6K), or even the price of another cable loan from Cable Co.
YouTube versions of key tracks used for final comparison:
1) Ahmad Jamal & Gary Burton Live (France, 1981), "Bogota” (36:35), Great playing and a demanding rapid fire instrumentals test (Cut 6, “Autumn Leaves,” is also a good test).
2) Sinatra Live at the Sands with Count Basie and the Orchestra, (1963, Reprise), "I've Got You Under My Skin"
The rendering of Sinatra and the orchestra tells a lot about how a system handles voices, as well as orchestral dynamics.
3) Bill Withers Live at Carnegie Hall (1972, Original Master Recording), "I Can't Write Left-Handed." Hymn to a returned soldier who got shot in the shoulder in 'Nam and lost his arm. If it don't truly sound like a hymn...
4) Talking Heads, Stop Making Sense (Deluxe Edition video, 2023). Test of emotional presence and ability to understand David Bryne's lyrics. Omega-X was head and shoulders above the rest in the latter.
