Try real NOS 1960s and 1970s Amperex (Holland and USA made) 6922 tubes and not the later ones branded as Bugle Boy. Also Mazda may give you the great high end you are seeking. I personally go for a totally different sonic signature in my preamp and use NOS Mullards...liquid and smooth across the entire spectrum with a firm bottom end.
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.
