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!

I have purchased a few pairs from E-Bay seller "audiotubes_de". His
name is Heinz. I paid anywhere from $200-$300/pair depending on whether
they were used but tested new, or if they were NOS.

Email him directly.

I have the Siemens tubes....to my ear the Amperex 7308's are a much better sounding tube.....not even close really. Mine are boxed up, I think the $10.00 each EH-6922's sound better.

I'm with Dave. I've owned, and sold three pairs of CCa tubes (the real deal, early
60s, grey getter variety). No matter what component I put them into, and I tried
them in about half a dozen components, they were always replaced with
something else.

I appreciate what they do, and they are indeed transparent...but they're not for
me.

That's the same seller (http://shop.ebay.com/member/?_frompage=findamember&_adv=1&_userid=audiotubes_de&_tokentext=383655&tokenstring=MqcnIwQAAAA%253D) that I've used for CCa's, 7308's and E188CC's. He's very reliable and scrupulous as a businessman. He used to have an online store, before selling on eBay. I haven't noticed him offering any CCa's lately though. Be certain not to buy any Siemens CCa's from the late 60's/early 70's. They are quite strident.
