Hi Rick,
I found some telefunkens for the 12ax7's and some Amperex White Label 7803 for the 6922. Not cheap, but a big improvement over the stock Sovteks. I agree that the 12ax7 has the most impact, but the 7803's picked it up a bit more in combination with the tele's. Once I had these in place this pre was every bit as good as my BAT VK50-SE but with more dynamics. So far, these are the only other tubes I have tried.
Best,
Dan
