Siemens CCa vs. Amperex 6922 D getter


I have a Audio Note P3 Silver with a Dodd battery pre amp. The Dodd calls for a 6922.

The Amperex WL GP PQ D getter in comparison to the CCa in my set up sounds dazed and confused. It is like a dirty window that needs cleaning when I insert the CCa.

I had the Amperex three weeks before the CCa came on the scene. When I first put the CCa in the music seemed to jump out of the speakers with such clairity that I was shocked that the Amperex somehow lost all that info.

So much for MR. Joe's report on the 6922. In my system they rock. I must say they work better with the TS 6SN7 RP than the Sylvania W metal. YMMV.

Anyone else have this experence?

...would like to thank all who suggested the use of the s & h cca's..i replaced my tubes in my first sound pre with 2 of the 'cca's' i had laying around..1960's version.. and my system improved several notches in a number of ways...again..thanks for the post
Siemens CCa's, whether U-getter '50's or halo 60's, can sound...well, not bright, but I can understand someone using that word in the absence of another. I think I hear sometimes a certain tension, not a sterility by any means, but a subtle default to focus rather than harmonic complexity; or, a default towards replicating a clear space infinitely, but less towards harmonics decaying infinitely.

I know that doesn't make much sense...Its a great tube and if you lean towards wanting liquid clearness and focus, the this is the tube for you.

Just an opinion (although, radical subjectivist rantings aside, not all opinions are equal...)
