I have always preferred 6922 based preamps . 6922s do vary in sound between good NOS tubes and new units like the JJ which I liked a lot. That's just personal taste. see
1It's not a matter of better just slightly different sonics. Solid state is a whole different sound. Me, I'd find a decent 6922 preamp and then play a little with tube rolling. If you're using a Schitt youmight try the LISST ss substitute. It's only $50.
