Seeking suggestions for 6922 tubes

I want to thank everyone who contributed to this thread for the wealth of information. There is so much to discover about the performance nuances of the different brands, and I will use this information in my search. Thanks in particular to rodman99999 and dekay.

I also thought that the idea about the adaptor for the Western Electric tube was fascinating. I never heard of that before.  

I'm very pleased with the pair of gold pin Amperex USN-CEP 7308s with large halo getters from early to mid 60s in my ModWright Elyse DAC. Very quiet and nice top end. Until this past April when I bought them, I had been gone through MANY different makes/models in this family and that's where my journey ended. I wish you the best in your search! 

There are a few tubes that are recommended time after time in this thread.  Some are afailable from sellers in remote countries.  How much do we need to worry about fakes?  thanks

see brent jessee’s page re 6dj8 fake telefunkens with chinese counterfeit silkscreening, informative... bottom line if you know these tubes, key indicators of their construction that identifies them, really convincing fakes won’t get by a cursory look by an experienced tube guy

what IS the worry is used tubes, with lots of hours, severe imbalance across the internal dual triodes, and noise/microphonics... let’s face it, these tubes are no longer made for 20-30-40 years now, folks test 'em, use em, pick the good quiet balanced ones and leave em in to make music, set aside the noisy crappy ones, so what remains available today are more of the poor ones that fail on one or more of the above attributes ... unless they are coming out of a reputable seller that tests on all these key parameters or from an old hand who has had gems stashed away for half a lifetime...

Thanks jjss
