i've been seriously considering trying to move to an external power amp for my main speakers (B&W 602's) but lack the $$ for purchasing a real amp. so, could i use the coolness of my HK's preouts/main-in's to bi-amp my speakers? i was thinking about buying two Y-splitters (male RCA -> 2 female RCA) and running them as follows: Y-out from Front L preout to main-in Front L and Surround L. same thing for the right side. then just run in 5-ch stereo mode and have bi-amped mains when i connect the speaker wire accordingly. my only concern is that if i play movies and it defaults back to 5.1 that it'll sound really messed up (or even damage the speakers) sending different info to the tweeters and the midrange woofers. will this work? opinions? suggestions?
