Guys, i need your advice please. While designing PCB for Sun audio 2a3 i occasionally discovered 1969 JLH solid state amp. Measurements of this amp showed even-harmonics (like in tube amp) and overall very good sound. And this amp turnes out to be much cheaper than my 6sn7-2a3. What would you say about the sound of both amps? I listebed to neither of them but listened to many tube amps.

I'm building this one at the moment. Just a different pre-amp using 6SN7 (Because I have them on hand) instead of 6SL7. Just a few minor changes. And the rectifier is an 83. instead of the 5Y3.
