My 6922 Tubes Are Too Bright!

I recently bought a Canary CD-100 CD player.  I swapped out the ElectroHarmonix 6922 tubes for Amperex NOS made in Holland since I had read a review stating that the tubes it came with were too bright.  Unfortunately, it's still too bright for my tastes.  Does anyone have a 6922 they would recommend that's a bit warmer?
Thanks!

I suggest u call Andy at Vintage Tube Services and speak to an expert.
  It sounds like Mullard may be what you need, he can tell you about the sonics of the 6922/E88CC Mullard vs. other brands. But premium tubes are not cheap.

The new production JJ/Tesla E88CC is a very warm tube and quiet tube that I have used in a CDP with success. I've also used it in a headphone amp. It's cheap so give it a try, not much to lose.

There are so many variants. This is one article that I found helpful:

But ultimately, it is a lot of trial and error.

Have rolled quite a few 6922/7308/6DJ8. The early Siemens 6922/E88CC with gray shield was one of my favorites and always sounded excellent, never bright. Sometimes they may be labeled RCA, made in West Germany.

I used the Siemens CCA grey-plate tubes in my tube DAC I used to manufacture.  Excellent tube, fast and clean.  They can be $450 a pair from Germany on ebay, but worth it. 

If your system still sounds bright with this tube, then there is something else wrong in your system, probably too much jitter from the digital source, or may be your preamp.
