I have an onkyo txds797 reciever and a full set of Infinity Alpha speakers. My 2 front speakers are alpha50's and are bi-wirable. manual says bi-wiring will improve sound performance but I am using Monster Z-series cable with banana plugs which is too thick to bi-wire. So i'm stuck on what to do. Do I keep my z-series cable and don't bi-wire, or do i bi-wire with lower quality cable. Don't know which will give me better performance. help please!!!
