tube upgrade for first sound

Has anyone been able to improve on the stock tubes in the First Sound preamps? I was thinking about trying the Russian 6H23. Any thoughts? thanks

Maybe this has been covered already, but it bears repeating, i think... 1) Aurios isolation/decoupling bearings - clean up and solidify the sound very nicely. Emmanuel recommended them, and as usual, he is right on the money.... 2) straight into the wall. I found my Hydra robbed a bit of the inner sparkle and life.

What would I ask for? I'm just getting into tubes so this is a whole new world for me. :-) Thanks Paul
