I'm doing exactly that with my Denon AVR4800: using a separate amp to drive my Martin Logan reQuests by running ICs from the pre-outs of the Denon to the inputs of the amp and then connecting the speakers off the back of the amp. Works GREAT.
Which receivers have decent stereo performance?
I currently have Yamaha RX-V795 driving a pair of Soliloquy 6.3 which does not do them justice. I can't afford an amp/pre-amp for now. Are there any receivers out there, used for less than $1K, that do decent stereo job so I can watch both movies and music sharing the same pair of speakers?
