noble100"I know my class D monoblocks provide significantly better sound quality in my system and room than any of the good quality, big, heavy,inefficient and hot running class AB amps I previously used."
Actually Class AB amplifiers designed for music Reproduction Systems are quite efficient although not nearly as much as Class D but they also avoid the distortion, artifacts, and noise inherently embedded in Class D products and components and if you're Class AB amplifiers ran hot then they were misadjusted as to bias or they were improperly designed or they had insufficient heatsinking.
