Anybody ever heard of EVI 6922 tubes?

I was told these are the best but can't find anything on them?
Perhaps you're thinking of these: (, which are the best current production 6922s.
Don't know the ones you refer to but I would imagine hit google and see what happens.
The best 6922 for you will greatly depoend upon your individual equipment piece and tastes.
buy 4 or 5 different NOS and tuberoll until your ears decide for you.

enjoy the music.
