I have a pair of the silver Torsions in my upstairs 2 channel system. I won't do a full review of these because you can sign up for the tour and hear them for yourself. But there are a couple things that are really remarkable about them that I don't think Jason emphasizes enough, because he's fairly modest.
1st, they are strikingly beautiful. When you see them in person, they look like audio art. When I spend a lot of money on something I want it to look good as well as sound good. Jason takes a lot of care and pride in creating things that look beautiful and badass.
2nd, the sheer amount of work and labor that goes into these things is incredible. Jason does not just grab a bunch of off they shelf cables, slap on some connectors and tech flex and call it a day. No, each cable is created as a bespoke piece of art. Let's put it this way - every single conductor is hand polished by Jason for HOURS and HOURS and HOURS until it is a mirror so perfect you have to look at it through an electron microscope to see any imperfections. And that's only ONE step of the build process. It's utterly insane.
As for sound, I'll be honest, I usually don't buy cables from audio manufacturers because I can build my own cables as good or better than what most manufacturers offer. The one exception is Hapa. There's no way in hell I can build to the level that Hapa does. Not even close. And the result is that the Hapa Torsion cables blow away anything else I've heard. They completely elevate my entire system. Putting them in (for me) was like upgrading all of my components, all at once.
