Siemens CCa vs. Amperex 6922 D getter

Mr T- You are correct about the "taste" factor. That's why I always preface my recommendation of the CCa with a note about their clarity and transparency, and mention the fact that some might prefer a "warmer" tube. Another possibilty is badly recorded source material. I've had just a few discs over the years that were obviously mastered on monitors without tweeters(or by a deaf engineers), the highs were so exaggerated. I've got one right now that I really like the lyrics on, but won't play on my system because it's recorded so poorly. I only listen to it in the car, with the treble turned way down. Mr S- That's why they(and the E188CC/7308) are so stinking expensive and rare now: In an accurate, resolving system- they just get out of the way of the music. Obviouly there are a lot of us that enjoy that attribute. Happy listening!!

...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

Enjoy your music Mr C!!

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...)
