I strongly preferred the early 60;s Siemans cca's. But the cheaper Amprex White Label PQ's were also good, abit wetter and less controlled. Hiss level may vary with tubes. Unit should be very quiet, just a tiny bit with your ear right up to the tweeters.
hmmm...

I am having problems with the left channel popping and increased hiss on that side. I think there is a problem with this preamp. I reversed the tubes to see if it was them, and the problem stayed on the left, so I suspect there is a problem in the preamp somewhere...

This explains the higher hiss than I was expecting I think. It's really unfortunate because it sounds great when it's working fine, but I think this one has problems somewhere...

I'll talk to the seller and see what my options are.

If you want to keep, and seller is not cooperating, send it back to Joseph Chow who designed it at AH and he will make it right.
