6922 tube rolling recommendations

Siemens E188cc 7308/Excellent choice.I used one in an Anthem CD-1.Best upgrade ever.Andy at VTS can help.You dont see tubes for sale on this site saying bought from VTS.That say's alot.

I have Siemans CCA in my Art Audio Diavolo and they are the best I've tried. Very hard to find.I see them on Ebay sometimes but don't know how to judge the quality.

I'm with Longplate; I love the sound of the Amperex 7308 gold pin tubes. I prefer those marked Holland to the USA version but both are quite good. If you have a surplus dealer in your town you might try getting a broken old Tektronics tube scope. Often they will contain several handfulls of gold pin 7308s as well as other cool and useful tubes. Best of luck.

I have tried Telefunken CCa's, Telefunken 6DJ8's (ECC88), Amperex 6DJ8's, Mullard 6DJ8's, Telefunken 6922's (E88CC), Telefunken 7308's (E188CC) as well as Telefunken and Tungsram versions of 12AX7 in my CAT Ultimate. I don't think that anyone can tell you very much about what will work in your system unless they have every piece of equipment you have. I recently made a change in speakers from Snell C/V to Vandersteen 3A Signature, a change which one wouldn't expect to be huge, since both speakers are on the warmish side. The difference was huge and forced me to completely reevaluate all the interconnects and cables which I was using PLUS the tubes in the preamp. Tubes that I was going to sell before now sounded excellent and the tubes which I was using had to be reconsidered. The only way is to listen yourself with at least the speakers and preamp you intend to use and then to make your own decisions.

Thanks for all of your responses.....Longplate has been so gracious as to hook me up with some spare amperex tubes....cool deal. Rayhall....I agree with you on system synergy...I'm most likely changing amps soon (SS to SET...big change), so I'll need plenty of tubes on hand to find the combination that works best (the jota I'll be demoing uses this tube, and comes stock with a brimar I think?) I'm keeping the rest of my equipment for a while.
I'll let ya know how it all works out.
