Following up on Audiofeil's post, he made a very important point regarding low noise. I went through 6 Siemens early 60s CCa tubes before I found two that were quiet in my system. Quiet CCa tubes are rare, and it's one reason they cost so much (not to mention scarcity of CCa in general, and buyer demand). BTW, the noisy CCa tubes cost $400/pair, too, but for that money, I insisted on having quiet tubes, and I kept returning them to the E-Bay seller until I had two that were quiet.
