Kevinzoe, I've tried Siemens 7308, Amperex 7308, Amperex 6922 PQ
and Philips 6922 SQ. All are excellent tubes. In my opinion, the
Siemens are the best, but you would also be very happy (I think) with
Amperex 6922 PQ White Label made in USA. They are very close to the
Siemens sonically, and they are easier to find. Don't let the scarcity of
Siemens 7308 tubes lead you into a sense that only they will satisfy your
quest for better tubes for your First Sound. Do a search for
"Amperex" on Audiogon, and you'll probably come up with
some for sale. If not, they appear from time to time with relative
frequency.
Also, you might read "Joe's Tube Lore" if you haven't already.
It's a good primer on 6922 and 7308 tubes. Here's the link:
