Unfortunately, as helpful as some kind of lending library like the Cable Company has except for tubes would be, it's just not practical.My c-j Premier 16LS2 preamp runs on three tubes per channel and I've never heard the Siemens CCa and 6922s separately so I can't really comment on how different they sound. The preamp is designed to basically combine the tubes for each channel into one composite triode.
If I had to guess, and it's just that, I'd say that similar vintages of both sound pretty much the same. The CCa's are supposed to be selected for low noise, but I don't know if that in reality translates into a quieter and more resolving sound. Maybe, maybe not.
I do have a pinched waist Amperex 6922 I've used as the input tube for my Premier 140 amp and IMO that is a very special tube in that application. They're also very expensive.
I have and like TFK 6DJ8s and 7DJ8s. They're just a small amount less resolving in my opinion than the Siemens 6922s and with just a touch more warmth and musicality. My taste runs toward a slightly warmer sound and that's why I really like the Amperex house sound, as well.
The most neutral tube I've heard that seems to combine the resolution of the Siemens with just that touch of TFK warmth is the 60's vintage Lorenz 7DJ8. I've never heard the 6DJ8 variant but in my limited experience and in my preamp, the 6DJ8s and 7DJ8s of the same vintage sound basically the same to me.
The Lorenz 6DJ8 family members from that time period seem to be really difficult to find, however.
Hope this helps some.
