I have the AVR-335. Very happy with it. I have Klipsch RB-5s for the front and RB-3's for the sides and rears. It's extremely warm and detailed.

Lots of different surround modes. The DSP 7.1 channel (available from the "stereo" button on the lower right of the remote) works quite well for listening to classical music, or progressive rock (Yes, Emerson Lake & Palmer, King Crimson, etc.) It tends to separate more music in the surround speakers from regular redbook cds.

The instructions can be very frustrating, but do take the time to learn everything as someone mentioned above.... it has a ton to offer. Great crossover abilities.
