Still torturing myself on equipment choices. *IF* I were to go the route of a separate power amp, say the Emotiva XPA-5or LPA-1, what would I use for a source switcher / pre-processor / preamp / surround decoder? Something like the Emotiva MMC-1? Or would I be better off going with a low-wattage AVR (like the Denon AVR-688) and just not using the built-in amps? Or should I save myself hassle and space and just go for the ever-popular Denon 3808?
