Audience AR 12 TS vs Tesla PowerCell 10SE Mk III

I can't speak to the others, but I have the AR6T and I feel it was money well spent. I used to own an AR6 and it was also excellent. Plus, Audience is a great company and stands behind its products. I don't think you could go wrong with a used AR12 if you need the extra outlets. They usually sell for very good prices on the used market. Unfortunately, many of us can't compare power conditioners side by side, hence the lack of response. The T was somewhat quieter and blacker, but I'm sure you wouldn't be disappointed with the non-T version either. Enjoy.

@Jazzonthehudson - I never got around to the AU24 Powerchord, but I would venture a guess that it would be a significant improvement and - 30 day money back. I'm going to do it when I have the chance. I remember the T as being quite a step up in terms of the purity of timbre of instruments, but remember, I listen to 90% classical and acoustic jazz, so I think the difference shows up more than if one listens to electronica or the like. Personally, if you like the AR12, I would stick with Audience, unless you want to go the Cable Co route, which is also cool if you have the inclination. But again, I wouldn't overlook the Powerchord.
