The main difference with my system now is an additional EP400. So now I run the Tube Amp/Denon SACD Player at 30W/CH in Trilinear Mode with 2 X M2s & 2 X EP 400s fed to the speakers from the Amp Speakers Out terminals. Even at only 30W/CH there is lots of power as the subs at 500W/CH provide the heavy lifting.
This system is easily as good if not better than anything that I auditioned in our local stores; however, a bit of heresy here - after a couple of years of listening, I don't hear a lot of (if any) difference in my Tube Amp as compared to SS Amps. But it is sure cool to have it softly glowing in a darkened room on a cold winter's night...
