I was just browsing through the Amp/Preamp forum and read a discussion regarding Denon's power ratings being measured with 1 or 2 channels driven instead of measured with all channels driven. Does anyone know how Nad's power ratings are determined? I had always assumed that the 100 wpc rating of my T763 was measured with all 6 channels driven, but now a seed of doubt has been planted. Anyone have the definitive word?
