AMP for Panasonic XR45

I have the XR45 and I run it as a 2 channel receiver bi-amping my speakers. From going thru the setup menus I believe it can be configured for a L/C/R with a output to a powered subwoofer speaker set. The rear channels will be folded into the L/R speaker pair.

I paid $340 and I think it's a great bargain. It replaced the well regarded
Rotel 1050 receiver (a former TAS cover story). I'm still using the stock power cord and I've read and been told that it greatly limits the product's performance. I use it in a bedroom system with an Apple G5 connected via Toslink feeding it uncompressed digital music files. The system is setup for background listening and I don't really have a feel for it's absolute performance envelop. All I can really say is that's it's at least as good as the $800 Rotel.
