Preamp 6922 tube help

So my favorite tubes out of all the ones I've tried are early 1960 Siemens CCA, i find them to have an exteremely clean sound, fuller flat, tight bass, great imaging, just everything you would want. But because my system is on the neutral, the CCA has tipped it to the brighter side because of the "sparkle". I was wondering if anyone had another recommendation for tubes that perform like the Siemens, with its sense of realism but without the brightness in my system. 

Here are the tubes I've tried 


Telefunken E88CC ULM - clean tubes but the bass is too rounded out.
Mullard E188CC - too warm, way too warm
Voskhod Singlewire - great tubes but just didn't feel like didn't have any characteristics
Reflektor Single Wire - seems like the mids were a bit warm, but very nice tubes, but i would always rotate them out after a period because they didn't feel too accurate, but very sweet. 
Amperex - Forgot which ones but the highs and lows were rolled off. 
Electro Harmonix 6922 - has a basic tube sound to them on the warm side of things.

Hi Whart, Yes this is Morinix from Steve Hoffman's forum (also Morinix at Audio Asylum). Thanks for the welcome! Interesting place here at the 'goN.

I was able to get a set Matsushita/National 7DJ8. Since it got so many recommendations and very reasonable priced. 

I want to say it did solve the issue of glaring highs that I experince. The first thing that hit me about the tube is that nothing stood out. The highs were clean and the lows were tight. It is defintlaty a good tube. It might lack the "magic" distortions that some of the other tubes are known for. Sometimes that magic leads to fatigue, or just draws too much attention to themselves after extended listing.  But there is no fatigue that comes from them, they are at the hint of warmth. They are what I am looking for and might end my search. 

The bass is not as quick and clean as some of the tubes I've tried, but I think it gets the balance of what a tube stage should do, to add back a sense of naturalness to the music. Very intresting indeed.

I'm always looking for authentic telefunken, mullard, or amperex, 6dj8 (variant) tubes. They are really getting expensive now however. I'm currently running telefunken in my preamp & amperex in my phono amp. It sounds fantastic. As far as a budget 6dj8, try a sylvania. They are not as good as the ones I listed above, but are pretty cheap in comparison. I like them better than the russians, & they are not that much more expensive.
