Maybe Avnut should listen to the newer designed amps before commenting - he probably never has owned any nor has he auditioned becuase if he did he would know better - I own a mAc 352 and it has a really balanced non fatigue sound quality - unlike say the Levinson 331 which I found to be edgy and brought listener fatigue. The big boy Mac amps I auditioned were great - just costly.The 30 year build quality is not bad either.
