I have the AVR-885, which for all intents and purposes is the 2105, only with a silver finish. It powers my classic 170's, old B&W center channel, Axiom QS8's and a Rocket UFW-10 sub with no problem. Sound quality is very good and power is decent at a rated 90W x 7 full bandwidth, 125W @ 1khz, though my old Outlaw 1050 rated at 65W x 3 channels driven seemed to have more punch.
