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!

Anyone can look at these two schematics and get a feeling for what would sound different? (Assuming similar components)

I wish I could help you more. Best of luck.
