Al, I already had Power Conditioners in the main system. I have a couple of Richard Gray units for a while and also a Vansevers reference unit as well. I also have a PS Audio Ultimate Outlet for the projector. When I auditioned the BCD-1 (before buying it) I played with the Torus unit in the store. I've never seen conditioners that generally do anything positive for amplifers. The 1st audition was using just Ayre electronics. After listening to a a few players, I narrowed it to the Bryston and one other and came back later for a second audition (with my own home made power cords and cables to better one-to-one analysis and also with components and speakers I was a bit more familiar with). At the 1st audition, I unplugged the Ayre mono blocks from the Torus and was shocked that I noticed a difference. Everything was more relaxed and there was a different timing to the music. Almost like going from a good CD to a good SACD of the same recording. At this time, I was not ready to go thru the expense of a new power conditioner (I just had my 14BSST upgraded with the Swedish magazine review mods and decided to sell my Thiel 7.2s and go with the Thiel 3.7s) and I'm also waiting to see what happens to the Bryston processor with HDMI and the projector market. So a power conditioner change was not in the works at least for the present. So I decided to try some less expensive tweaks to use with mine. I now have a bunch of both of what I noted in my previous post (both Audio Prism and PS Audio products - I believe the PS audio works a bit better but they are more expensive). They seems to work in conjunction with my current power conditioners to remove noise from my electrical lines and give me most of the sonic improvement, if not all, of what I heard with the Torus, with the exception being my amps are still plugged into the wall. So I'd guess if at some point I went with a Torus, I might hear a bit of additional improvement. It was just a question of using what I have now and working with my funds at this point.
