I'm about to wire up a Yammy 2300 to a pair of Kef Q5's. I could Bi-wire in the normal sense which is pretty straight forward (1 output on amp to the two separate inputs on the speaker x4) or I could use the Main A + B outs on the amp as separate circuits (A=Hi B=Lo to Hi/Lo on Spkrs). Is there any advantage in doing this and does this affect the impedance setting? The speakers are rated a 8 Ohms overall. If I'm running one amp circuit into the low end and another into the high end does this change things??? Any help would be greatly appreciated as I've getting myself rather confused over this... and I want to wire them up tonight!
