All, my magnepan ribbon wires coming lose have driven me to upgrade to Polk LSIM707's. But I'm curious if my current Denon AVR991 receiver is sufficient enough to drive them in that manner they were designed to be used. They arrive in less than 18 hours but wanted to get some thoughts from people more intelligent than I regarding high end audio. Thanks Room size 10x20 Centers is B&W LCR3 Rears are B&W LM1's Sub is a mirage 12'' Thanks
