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?

The Amperex sounds dazed and confused and the CCa makes the Amperex sound like a dirty window that needs to be cleaned. The CCa has much more clarity than the Amperex.

I don't think the Ampeerex is bad as it sounded great until the Siemens came along.

I have a pair of Amperex 7308 coming from Andy (going on a 30 day wait) that will be interesting to try out.

I compared several tubes in this category in my Dodd battery preamp and found the Amperex 1960's white label and Seimens 1960's CCa's to be the two best. Between the two, I much prefer the CCa's.

In my system the CCa's have much better texture - just sound richer without giving up bass slam or top end. Dynamics are great, also.

I tried a couple pairs of both, so I got some diversity there. I do plan to keep a pair of the 7308's around to change things up once in while.
