Longplate: I don't think you gave the SLI much of a chance with the stock Sovtek garbage. We've all been playing with NOS goodies and exchanging our impressions.
I think I would be safe in saying that we all agree the Siemens 7308's are KILLER. Maybe the best 6922/6DJ8 for this amp. On the 6SN7's we're a little split. While I prefer the early 50's RCA 6SN7GT others prefer the Raytheon's. We all like the Svetlana KT88's.
Granted, this is an additional $500+ worth of tubes, but it makes all the difference in the world. And you can never have enough NOS tubes lying around. :-)
