I am a newby...Everything I have is vintage including me. My favorate amp is my Pioneer Series 20 power amp. It weighs 45 lbs. It is pure class A and produces 15 RMS watts/ch. It gets hot enough to cook on. I use it in the winter to warm my study. It sounds most accurate on my Mission and ADS speakers. My Yamaha M-4 sounds more accurate using B&W's and NHT's. .
