Not with 6922s but I can testify that the Tesla Crosswords lable made other tubes which I think are very good indeed. They are all too much money these days but you can always sell them to minimize any losses. The only person's opinion that counts is yours and you have to try a few others as well to know if these are optimal. If you have a deep pocketed budget. I use CV2943s AKA as a E88CC-01 which is a Mullard military issue tube which sounds more like Siemens than a Mullard. I don't know who has them now but I got mine from Sweden Tango Tubes.

Here's my question? I'm wanting to change tubes in my phono preamp(ARC PH-3SE) Currently running 6h23n Russian tubes.
Looking to switch to either tesla E88cc/6922 saber logo or tungram E88cc(Hungarian) tubes.
Has anyone had experience with either tube? Would either be an upgrade from my current tubes?
