Well, that's still more money than the originally-presented options. But, yeah, if you want to spend $600, that seems like a no-brainer.

Personally, if I were going to spend $400-500 on a 2 channel power amp, I'd look for something a little higher end, used. Maybe a Rotel or Parasound.

Or get one of those QSC pro amps that people seem to like so much.

Rich, why do you think that a new 2-channel amp is going to make your HT sound "better" than the Denon receiver you're using?
