Seeking suggestions for 6922 tubes

The best 6922 I've heard are the Amperex D Getter from the late 50s early 60s.  I prefer them to the 7308.  I used them both in my MHDT Orchid Dac and the Decware SE84UFO. 

Read what petg60 says in this thread; I assure he's right:

Be careful if your preamp is an Audible Illusions.

What is the preamp and the DAC.

If the preamp runs the tubes hard then this will slim down your choices.

If the DAC uses the Telefunken's in a buffer stage (and you purchased higher than buffer grade tubes) you could try them in the preamp.

You could try something like this in the DAC and/or the preamp (see following link).

I've used the longer lasting version of the tube in the link, but good testing units of them dried up a long time ago.

Anyway, I may be able make a few recs once I know what preamp you are using.

Tungsrams are nice.  NOS Teslas are also nice, but seem to have gotten expensive.  I think white label Amperex, either Herleen Holland or USA, are the best option.  I have at least 60 of them.  :~)
