Thought I'd chime in again. Now I've logged a goodly number of hours on the AC12. Unfortunately, to the folks who are looking at the AC12, I had added the Teslaplex outlet which would skew my observations.
This cord seemed to change a lot during breaking. I might have 4 weeks on it now which in this house is a LOT of hours. It has really become a lot warmer than what I would have expected. What this meant in my system is that for the first time, my tube preamp is no longer adding to the musicality, subjective of course. For our ears it's too warm. With the PS Audio PW DAC feeding the Pass 350.5 directly through the Power Plant Premier I'll say this. Glare, stridency, fatigue, gripping the remote, being fidgety, lowering the volume, are no longer in the sonic picture. The more I turn up the volume , the better it sounds. And it sounds amazing. Not the last word in transparency. Soundstage as good as I've heard in my room to be sure. How much the AC12 sets the stage on this is unknown until I further study with another really good cable. Anyone want to drop by with a Shunyata Python?
