The NAD T750 being a receiver, not really a 5 channel amp, you need to make sure it can be setup to send a full range stereo signal to ALL channels ALL the time. For instance the rears channel amps may produce a signal only for a DSP generated surround sound. Same with the center.
If you can figure this out, then if more pwr will make the speakers sing and you have it, why not use it. I would recommend u go to Home Depot and spend $15 on 14g copper wire for multiple runs of speaker cables. Use this and experiment before buying cables.
