I had the Sigma V2 XLRs here for a week from The Cable Company lending library, and they were extremely impressive. They didn’t jive with my system in every respect, but when I went trying out alternatives like an even more expensive Transparent Audio Reference Balanced, I realized that you have to spend way more money with other brands to get the low noise, deep soundstage, detail and dynamics of the Sigma V2. The TA didn’t even come close in terms of overall fidelity, but did have some strengths of its own. I’ve actually never heard anything else with so much detail, dynamics and soundstage, nor with such a deep black background. I’ve never heard any interconnect improve the fidelity of my system to that degree.
If I had one complaint it was that the midrange was a bit recessed and the lower treble was intense and biting in my system. The speed was also sometimes a bit much because all the edges were very sharply defined rather than round or soft. When I went back to my previous Wireworld Platinum Eclipse 8, the WW was better tonally balanced and more relaxed, but so much of that resolution and transparency was lost. The Sigma V2 is just on another level.
I actually found that even the demo cable changed in sound significantly over 5 days. It’s possible that the tone would have settled even more over an additional week or two. If they are anything like the Sigma V2 power cables, of which I have 3, they take a really long time (weeks) to mellow on the top end because of the silver in the cable.
Nonetheless, I am realizing that it is pretty unlikely that I’m going to find anything that can compete with the Sigma V2 for less than 10k, and I’m just not going there. A $5k set of interconnects is already insane, if a level of insanity I will accept for the audio quality. More than that, I just can’t do. There isn’t a whole lot of buzz or marketing about these cables yet, but if they match well with your system, they are a ridiculously good.
