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.

A lot of Siemens stuff was made in Germany alright , East Germany.
Not that they sounded bad , but often did not last long . .

If you find real Navy tubes, not JAN , they were the best ever made .
Good luck finding  them though .

I've had several amps that used  6922's and found Amperex to be best all around . BUT there are many fake Amperex being sold, often by people 
who don't even know they are . Won't happen with Andy so worth what he charges .
As lowrider57 said , also hard to go wrong with RCA as well .
There were some nice sounding ones labeled audio research company
W. Germany but not seen them on here .
