Sun Valley vs Sun Audio 300b

Any thoughts on how they sound?

Sun Audio is extremely simple circuit with no NF and Tamura.

Sun Valley is more complicated circuit w/GNF and Hashimoto.

I don’t mind building either, but hard to find anything out there comparing how they sound. Each has sales reps in US that want to push their own.

Sometimes simpler is better, other times stability is better.

thanks in advance!

I will try and learn some from Skunkie’s work on the Sun Audio. There seems to be more awareness about the Sun Audio amp I guess maybe because it’s been around for longer in its current form. I get the feeling the Sun Valley may not have had the Hashimoto as standard for as long. Out of curiosity what is wrong with GNF?. Is it considered a less pure design as in if it was a better circuit it shouldn’t need it ?
