Warm sounding 6922 Type Tubes

Why do dacs have tubes?

@earthbound The Mullards are starting to warm up and probably didn’t give them enough time to break in. I guess there’s no set time especially for NOS tubes.
 

The real problem is I have tinnitus in my left ear and it’s extremely sensitive to high frequencies so that’s why I lean towards a warmer sound. I can no longer listen to loud music without being affected. I should have mentioned this initially.

@ronrags Welcome to the tinnitus club. Sigh.

among modern production 6dj8’s the jj is a warmish sounding tube

mullards and brimars among old stock ones, as well as us made ge’s

FWIW, after many years I stopped chasing NOS tubes (for the most, part depending on how old old is) and when selecting 6922's with a warm tone I use JJ's. They are cheap and fairly dependable, although I usually keep a few spares. For clearer toned 6922s I usually use 6h23s or EI 6922s gold pins, the former are fairly cool, the EI's a tad warmer).
