Class D is not high on the list right now. Maybe I'll give W4S a shot sometime down the line.
Rdavwhitaker, I am starting to face the reality that I probably am a "tube guy" -- I like the VTL a lot, as well as my Almarro A205A MkII, and haven't found a reasonably priced SS amp that can produce that kind of organic tonality and richness. It's just that if I have to nitpick, which we all do, the VTL is colored a shade dark. The 2500A is an interesting prospect. Have you owned or at least spent some time with this amp? How does it compare to the ST-150?
