The Pioneer model is 8 or 9 years old and would be bested by any current mid level AVR. Any processor will kick it to the curb as well, including the XMC. As i mentioned earlier, the XMC is dated and missing features now common on AVRs. I got a Denon 4520 for half off and the SQ upgrade over my 5 yr old Onkyo is stunning. I just checked Accessories4less and it's now over over 200 less than I paid, a crazy good price.
It can drive an amp should you want one. Anyone out there, if you're looking at a new AVR, get this Denon. The price is amazing and the feature set is top of the line. The only thing it lacks is Atmos, which is why it's on clearance. I've had it for 2 months now, and in my 25 x 14' room with 7.1, the sound performance is the best I've ever had. It actually bests my high end 2 channel system in some cases, but Audyssey will do that.
