NAD M3 vs NAD C370+C270 Dual Mono / C372+C272

Hi,

Does anyone have any audio quality feedback on the integrated amplifier options:

NAD M3 180W Dual Mono Amplifier (90W/ch)
vs
NAD C372 IntAmp + C272 Amp bridged for dual mono (400W/ch @ 8ohms)
vs
NAD C370 IntAmp + C270 Amp bridged for dual mono (300W/ch @ 8ohms)

Will be used on Monitor Audio PL200 or PL300 speakers.
Thanks!
