Nelson Pass, a brilliant SS amp designer. Check out his patents from the 70s to the 90s.
Perhaps he should design an hp amp.
So far my first Watt F1J is the best amp I've heard with the HE-6 as of yet. Other than the $8.5K SimAudo amp I heard at the audio store with the HE-6. Nelson is a great guy to deal with as well.
I bought the F1 from SoupRKnowva and sent it to Nelson to convert it to the F1J. It's been one of my best purchases thus far.
If I wanted to copy emulate your steps to F1J/HE-6 nirvana, what kinda dough am I looking at for the F1J?
