Due to a new rec.room I have enough wire to bi wire. I have a choice of using kimber 8-tc or Audioquest type 4+spread spectrum hyperlitz. I would like to avoid cutting both and doing a listening test.I would like to keep one of them whole so when my wife changes the room layout I can have a longer run of cable if needed.Can anyone suggest which cable I should leave whole and which I should bi wire with?
