For your price (used), don't forget the Cary Cinema 5. It's a great amp, I lived with it for quite a while, moving from McIntosh solid state. It has a good combination of what you are looking for.
Best multichannel amp for music?
I got a Theta Dreadnaught-2 which doesn't fully satisfy me. It has notably better mids and highs than the older Bryston I replaced (nrb series), and I like the character of the sound a lot better, but the bass is kinda weak and boomy in comparison and it doesn't localise as well as the Bryston. Are there any multi-channel amps that would have the strengths of both? I'd like to stay around 2500 used. Theta front end, Snell C/V speakers. Thanks. -Dave
