Siemens CCa vs. Amperex 6922 D getter

Siemens CCa's (pre 1968) are NOT the least bit strident, bright or glaring. Any system with a frequency imbalance/glare/sloppy bass/etc can make the very best tubes sound bad. That's just a fact of life. People that don't know any better will install a very transparent cable, interconnect or NOS tube in a system that isn't right to start with, and because the new component reveals a shortcoming in the system- blame the new component. I've watched those types chase their tails in this hobby for decades now. Of course- They're always right! Then again- SOME folks out there are teachable. Have fun!

I agree that the Siemens Cca( late 50's,early 60's) grey plates are very special tubes. In the right circuit in a resolving system, they are truly magical. Unfortunately, they are getting rarer and more expensive as time goes on.

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
