Hi there, I'm after a NAD T753 which is a six channel amp with pre ins & outs. I'm not that bothered about rears so I was thinking would it be possible to rob those channels to bi amp the fronts? Therefore, a RCA-RCA cable connecting the following.... Front Left pre out into rear left pre in Front Right pre out into rear right pre in then take the rear speaker outputs to the fronts bi amp speaker posts. That ought to work except I don't know if the rear 'pre ins' will work under normal circumstances (do they only work when ext in is selected?)....so, can anyone advise? Or can anyone think of any other way of getting a front speaker bi amp scenario out of a 6 channel amp!
