I personally don’t like the sound of Cryo, nor do I like the sound of line conditioning, or over built outlets. Keep in mind, I was one of the original "Audiophile" outlet designers. I was wrong! After doing the follow up listening on the "more mass" outlets I realized there became black holes in the sound stages. Same was true with Cryo treatment and line conditioning.
If your going with smaller soundstaging, hyper detail (fatiguing to most ears) and an upward shift, Cryo and the other things I mentioned are fine. But if your joining the ever growing bigger stage club, you will want to go low mass and heat Temp-A-Cure treating.
The key to all of this is experience, and by that I mean, hundreds of systems vs a few. Once you get use to hearing the Cryo sound, it can drive you up the wall. At first it sounds clean (really clean) and you think your hearing more detail, but the more you listen you start to hear, and see, that parts of the staging has collapsed almost as if part of the connected flow is gone leaving a black hole where there use to be content. Second thing you will notice is your rock collection has become unlistenable, as if the engineers have made a recording mistake. But the reality is you have chopped away at significant sections of the recorded code. Ever put on a recording and it sounds like a scratchy shouting tin can? This means the recorded code (content) is not making it’s way through the audio chain intact. The high end audio "experts" have screwed up in telling you this is an engineering problem, but in fact these recordings are just fine. It’s the high end "technologies" that have screwed up. Part of this is Cryo treating.
