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

Should be acouple of weeks. I'm keeping my fingers crossed. :-) It meets all of the technical issues I have regarding DC leakage and all. I've tried 2 other tube pre's as well. I've been climbing the ladder. This is the end for me, no matter what. I hope this is "the one". :-) How is your Supratek?

There are a bunch of highly satisfied FS oweners here - we want to know more about your rig. Also, allow the thing to break in at east 3 weks before coming to any conclusions - AND REMEMBER IT INVERTS PHASE, so you need to account for that.
