I'm actually pretty happy with the receiver other than the fact that it didn't quite have the power for my fronts.
I put it in Stereo when listening to the turntable (direct into receiver using it's phono stage for now) and use surround modes for theater or 5.1 audio. Listening to Wish You Were Here Immersion Edition on BluRay this morning in 5.1 was wonderful! It breathed new life into tracks I've heard thousands of times.
I should probably try biamping the fronts to give them a theoretical 280W instead of a theoretical 140W but I'm wondering if I really have much to gain with a higher end amp vs. the Denon POA which to me has been great.
The KEF Reference 203.1's have 5 speakers to drive in each tower so extra power is good. FYI, they actually have binding posts to Tri-Amp.
So I guess my real question is, how good are the Denon POA-2200/2400/2800/1500 amps vs higher end models out now? Will I really notice the upgrade?
