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.

I've used that Reflektor tube in my Dac.For what it's worth,it has very good bass in that application but nothing special about the highs.Mullards seem to have the most extended highs.
So I have been down the road of several of the Amperex, a couple of Siemens, Tungsram, Telefunken, and I forget what else. Never been a fan of a Mullard that I heard, one of those tubes would have to be far different than what the typical Mullard house sound is. 

What I really want is a tube that sounds like a good transistor! I don't want tube warmth, sweet highs, or gobs of texture. To be honest I used to be a tube guy, especially SET, but these speakers have no interest in playing nice with tubes. Even just one lousy pair in the pre drive stage of the amp. 

So why am I torturing myself? Well I own it, and I wouldn't care if I sold it, but as you may have noticed with COVID19 very little audio equipment is selling, its not a high priority for folks right now. So I own it, and figure I might as well as try as hard as I can to get this thing voiced to where it works well with my JBL 4365. Now I put a pair of Maggie 1.6QR in front of it and I am looking for a tube like those Amperex, as that speaker is much more upfront and wants a bit of that tube goodness. 

But with the JBL I want a tube that sounds like a quality transistor. 
Well then, Amperex and Mullard are out; they reveal lots of textures.
IME, the 7308 Siemens West Germany would be worth a try. And with Telefunken, there is a difference between the smooth plates and the ribbed plates.
