Well, not that anyone responded, but I figured I'd give an update.
I just grabbed the Denon AVR-5800. It's the only receiver I could find that had (from all reports) a superb power supply, ample wattage, terrific sound in both 2 channel and 5.1 surround, and last but certainly not least, two sets of 5.1 analog inputs. Having never been looking for something like that before, I didn't realize how rare that feature is!
I'm going to be sad to see my silver Rotel beauties go. :~( But my saddness will be countered with the joy of playing with new toys. A kick-butt HTPC and huge honkin' AVR should wipe the tears away.
