As a follow-up...
I went with a Denon X4700H receiver and a PS Audio BHK 250 2-ch amp driving my 2.3s. Listening in Stereo mode (2 ch + subs, 60hz crossover) is divine. My Krell Home Theater Standard NEVER sounded this full and smooth. It's a cliché, but they sound like new speakers. I'm just sitting here listening in awe.
