Warm sounding 6922 Type Tubes

Glad to hear they are getting better. I too have tinnitus and have had quite a few tubes bother me in the beginning and then settle down. Happy yours did some settling in. 

I hope the dac situation works out for you. It is annoying and can be costly. I sold some brand new Zu speakers because they bothered my ears and caused headaches. Always a fear when purchasing new equipment. 

My Tubadour 4 took 10 months to settle in.  That corresponds to advice I received about the output transformers.  They're apparently quite good once they're broken in which takes forever, at least 500 hours I'm told.  I got mine the end of October last year and it just this past month settled down nicely up top and boosted the bottom.  That's about 500 hours play time for me.  I suggest don't toss it just yet after eight weeks.  

+1 on the CCAs. I also bought the Mullards from Jesse, but I lost too much of the good stuff. The cca is so good, resolution without etch.

@wlutke Thanks for the info. 
 

@earthbound I forgot I purchased another Mullard from Brent Jessee in the past. This one clearly shows it as a Mullard ECC88 and the other was hard to read but the box said it was a 6DJ8  manufactured by Mullard for IEC. Even without much break in, the ECC88 is smoother and less bright than the other Mullard. They are both designated as a 1964 production type but they do not sound the same. So now with this other tube I can say I’m happy with the sound.
