6922 tube rolling recommendations


I've been tube rolling tubes in my Bel Canto SEP-1 preamp.
I've gone from Sovteks to Jan NOS to Mullard(1970's version I think....$35/ea from Triode Elec) The Mullards sound much better...quieter background, better top end extension...it's really sparked my curiosity about trying other NOS tubes. I see VTS selling various Telefunken, Siemens, Amperex, and other older Mullards. Can anyone recommend a good step up from my current Mullard gold pins?

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.
I don't have the same pre-amp (I have an Audible Illusions 3A), but when I pulled out the Russian tubes and put in some Volvo (1963 tubes)6DJ8/6922's from the Parts connection, it blew me away! I've tried several others, but these have been the best in my set up.
I own the Bel Canto sep 1 which came with amperex 6922's. I hated the sound of the pre-amp (harsh and shrilly) I decided to change to telefunken 6922's to give it one more chance to shine.(By the way Kevin Deal woundn't sell me the telefunken 6922's to me because I bought my pre-amp through Audiogon) With the telefunken in place the sound is richer with more resolution. The difference between the two tubes was astonishing. best of luck Harvey
Run a search in the archives of the "tubes" section of audioasylum.com and you'll have more opinions than you know what to do with. Also have a look at "Joe's Tube Lore" in the FAQ section. But it's all equipment/system sensitive, so ymmv with any of this. Personally, I like Tungsram E88cc's in my Melos MA-333. Have fun, Jim
The best place to find out more info about various 6DJ8/6922/7308 tubes is at www.audioasylum.com Check their FAQ section. There's an excellent post specifically comparing various 6DJ8 family tubes available. I find it excellent reading. But, of course, results will vary depending on equipment. Also, there are various vintage for each tube. That said, I ended up collecting about 300 tubes in this family within the past 3 years, and was able to test different ones in my system. I've just tried some Siemens CCa in my system, and found them to be too lean and dry for my system. Every other tubes has tradeoffs. For me, the best one so far seems to be the Mullard 10M 6DJ8s. Except, they are very, very rare. I've settled for Amperex 7308 PQ White label.
