When I have the money and the space to start experimenting with separate amps, I just might do so. But first I need to do the following, which science tells me will definitely make a difference: new TV, new surround speakers, new HT receiver with DPLII and component video switching (and maybe HDMI for future-proofness), new CDs/SACDs/DVDs.

Maybe after all that I'll consider trying separates vs. integrated.
