It's a 525, the same one as kcarlile's. Getting kind of old but I love the Logic7 decoding for a lot of classical recordings. I don't use the main power amps in the receiver, although they will drive the M80s without problems. The pre-outs go to an old class A/B power amp with 200 watts into 8 ohms, more into 4 ohms. Much of the time, I run the M80s and M22s on an A/B switcher, both with the EP500.
