My NAD amp output power is rated as: Power output Stereo Mode 2 x 80W (8 ohms within rated distortion) IHF dynamic power; 8 ohms 2 x 115W IHF dynamic power; 4 ohms 2 x 185W
The M80 will only be used for audio and not home teather, since I have a deticated HT room already.
I think my first step would be to audition them, bring my CD along to see if I can hear the difference.
