I presently own a Marantz Pm7200 KI Sig and I am wondering if I should change it for a NAD C372T. The NAD has a power output of 2 x 150W and the Marantz 2 x 95W. I will be using it to drive the front left and right speakers in a 6.1 system. I have been told that my FR L + R - PMC TB2 s sound better the more power they get. The Marantz does not amaze me with its sound quality. Is there anyone here with experience with the old NAD C370? Will the NAD sound better?
