Interesting stuff gentlemen. I am using 4 Denalis (3 in Mono and one in stereo driving Aerial 20Ts, Aerial CC5 center and Aerial 7bs in the rear, complemented with an Aerial SW12 sub. I have an Aesthetix Calypso Pre Amp, Aesthetix Rhea Phono, VPI TNT6, Sony SCD XA777ES, Lexicon MC8B, so I can assure you that these babies not only do wonders for 2 channel, but you ought to hear them in a complete 5.1! Entire system run in balanced mode with Synergistic Research active cables. Peter's amps possess the ultimate in delicacy and detail or bone crunching power!
