Need multi-channel that's great on 2 channel

Gang,
I'm looking for a multi-channel receiver that's GREAT for two-channel listening. I'm thinking of upgrading what I have, given the space I have to play with. Most of the time I listen to music, not watch movies.

Arcam's AVR600 keeps getting mentioned; are there others that are very good musically?

Any input would be most welcome,
Jeff
