I have a pair of Klipsch RF3II's and am interested in bi-amping them. I am using my Marantz receiver as a pre-amp with a Parasound 5 channel amp. Can i use the 2 front channels of my receivers amp to bi-amp the speakers? I am not using them now so i figured i could use them to power the woofers and the Parasound to power the tweeters. Has anyone here bi-amped the rf3II's? Should i just bi-wire instead. Suggestions/comments welcome. Thanks in advance.
