Of all my amplifiers believe it or not this is still my favorite when I listen to CDs. It has wonderful pace and musicality. This is my original Zen Triode amp and I still enjoy it. Of course I listen to all of my amplifiers - that's the reason for having a good room and good sources. When I listen to this one, I usually use my corner horns.
