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.

I am not an expert, but I don't think the Amperex A frames are nearly as good as the earlier halos.  I have had particular good luck with 1962 and 1963  Amperex USA with Navy logos.  I also have some French Darios made by Amperex that are excellent.
Those and the JANs were the Navy tubes I was referring to.  I managed to stockpile quite a few about 5 years back.
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 .

To my ears the Matsushita tubes suggested above are no better than new production JJs.

Might take a look at Mazda 6922 (Brent Jesse carries them)
