Looking For Candidates For That Mythical 6922 Tube

I have spent a bit of time looking at 6922 tubes for a PS Audio BHK 250 Signature. I currently have two tubes that work relatively well, but really are not exactly what I need. 

So far it has been a pair of Siemens 6922 Gold Pin branded under RCA. Or a pair of Telefunken 6922. 

The Siemens have nice space, and a rich mid band. However the top end does not have the clarity and energy I would like. The Telefunken are more extended, but are lean in the upper mids, and have a bit of a threadbare feel. 

I have used Amperex Bugle Boy Holland and Orange Globe. I have tried some tubes from GE, Sylvania, Tungsram, and new Gold Lion. Nothing else betters the two I am currently using. 

Anyone have any recommendations that strike a balance between the Siemens and the Telefunken? I have read a bit about the Reflektor 6N23P with silver shield from 1975 as being a desirable tube. Any thoughts?

Any info you can pass along would be appreciated.
