Tube rolling 6922 tubes looking for transparency

I have a sunfire classic vacuum tube control center pre-amp that uses 3 stock sovtek 6922 tubes. I am looking to tube roll to a tube that is (reasonably priced) with a little more transparency and air! I tried tube valleys recommendation of Jan-Phillips low noise 6922 and it was more transparent and would have been perfect but apparently this is one of the pre-amps that has a microphics problem when using these tubes. Does anyone have experience with a (reasonably priced) 6922 that’s a little more transparent with a little more air than the stock sovteks!

Much good advice on Amperex and Telefunken.

One great value, the Toyota/Honda analogy fits, is the Tunsgram from Hungary. These are quiet, pretty neutral, with good extension in the highs -- not too bright, but plenty of air. Bass is not as strong as the better Amperexs, but still better than many other tubes. These were a pleasant surprise when I got them as part of a bundled purchase...Cheers,

I've tried quite a few 6922 types in my tape preamplifier (Bottlehead Repro)including the Siemens, Amperexes and Teles. The 6922EH is not a bad tube and Bottlehead and CJ get good sound out of it, to wit the ART and GAT.

One tube that you might want to consider that won't cost an arm and leg and has very good transparency, detail and low end extension and tightness are the Telefunken PCC88/7DJ8s. 7308s and E88CC/miniwatt amperexes have a bit better midrange presence and ambience but the low end is not up to the teles.

A good reasonably priced 6922 that has good balance top to bottom, is quiet, and doesn't get alot of press is the Japense made Matsushita. To my ears, they sound better than the new 6922's being manufactured today.

What about a Seimens/Phillips 7308 platinum grade from Upscale $50?
