Al,
I agree with your post, Dennis Had has proven success, yes. The problem is as you note when you attempt to cut cost. I’m not saying you need exotic premium transformers but they do need to be of reasonably high quality. Also wimpy power supply design is a certain recipe for poorer sound quality. He didn’t have these compromise concerns with his high quality Cary SET amplifiers, he used quite good quality parts especially output transformers.
