Supratek tuning

To all supratek owners

My Chardonnay arrived a week ago. It's superb. Plus, I have the chance to turn it even better. From the gain switches to tube rollin' there's a lot of space for improvement. So tell me:

What kind of sonic result do you get by experimenting with the gain swithes at the upper and back sides of the preamp? Just less/more gain? In what positions (for both switches) do you get the best results?

It seems the best 6SN7 tubes for these preamps are Ken-Rad Black Glass VT-231 and Sylvania Metal Base 6SN7W. Which one of these has tighter bass? Which one has sweeter highs?

See you,

Yes, same thing within my system: more or less gain; more or less freedom with the volume knob. That's it. Nevertheless, Mick states that tuning the gain switches has sonic effects and I suppose this might happen to other Supratek owners, with other systems.

As for the valves, would you recommend any valve in particular (within the Supratek valve-types, of course) for tighter bass?

In my system, Sylvania VT-231 or Sylvania 6SN7GT, 1950's, green-label, bottom-getter. The former is a little lean to some ears, the latter is slightly fuller. Both have excellent top-end extension w/sweetness and tight bass.

Ok. I have the chance to try (to bid on) a pair of new in box Sylvanias VT-231. Are you aware of the fair price for these?
