Unusual problem: we have a nice entertainment center, but the component shelves are only 16 1/2" deep. I figure I need at least 1*1/2" in back for cable connects, so that leaves only 15". I'd like to buy a decent 5.1+ receiver in the $500 - 800 range, does anyone have a suggestion? Don't need to shake the foundation, but would like multi-room pre outs for a whole house amp. Thanks!
