I've been curious about the Yamaha amps that start in class A and then switch to class AB as power increases. Why is their switching circuitry considered so special? My problem is that I can't get reliable information on the web. Whenever I do a search, I keep getting get this Yamaha restoration place. They have some information but I don't know anything about the veracity of their material. (I have trouble with businesses that don't have a street address.) I've seen stellar reviews for the M series amps but all those reviews looked like advertisements for the same restoration place. Could someone point me to a web site with accurate, unbiased information about the so called class A switching Yamaha amplifiers?
