Long story short-- I feel that I have pretty much run the gauntlet on the 6922 tube variants over the years. I even had my eye on a BHK
preamp wondering exactly what improvements I could render by adding a pair of my all time favorite tube . I did not buy the Pre so I may never know . I have a copland 305 CTA I decided to keep . It uses 2- 6922 tubes .
I want to say that about the only 6922 tube that I have not spent time with over the years a CCa . So I really can't say too much about that .
But I feel the best in my gear over the years would be the 6h23n or the 6n23p russian Voskhod not the Reflektor . Early 70s around 73, 74. 75
or so . I bought a nice pair of Reflectors to try but they just did not have the natural tone in my system that the Vokhod's do .
The tubes are a giant killer and can be had on ebay at very good prices.
Be careful though , most all are out of russia or the Ukraine and they advertise NOS but most are used to some extent .
I have had pretty good luck overall with most of my dealings with them on ebay.
I have a tube tester and I keep backups around so if you want ?
PM me and I will arrange to send you a pair on loan to try .
They will be used but they will give you a pretty good idea of what you can get.
One other thing , you want the single post 6h23n/6n23p from the early to mid 70s .
DO NOT GET- the 6h23n-EB or the 6n23p-EVs . They are a more
rugged version but don't sound near as good .
Also--- I am not a big fan of Russian tubes . these are the only ones over the years that I feel really stand out . Even above the European tubes.
Hope that helps .
Just my 2 cents worth. YMMV
