I have had 4 RSA conditioners in my system along with a stack of others and the only one I can live with happily is the Acoustic Revive RTP Ultimate. No sins and a completely organic, natural sound. It sounds very different from any other PC. If I had to choose a more traditional PC, I would probably pick the Sound Application but the RSA stuff is not for me.

I've been looking at these for sometime. The Dimetri looks really interesting. Anyone have one? Pros / cons? Currently use the Audio Magic Nexus.
