Tube rolling 6922 tubes looking for transparency

I love 6922's and have tried many brands. I agree with Tvad and Tpsonic, the Amperex and Siemens are the best I've heard with Amperex being my favorite. You might get lucky and find a trio "reasonably priced" ones. If not, consider the big picture. If you have to pay more, they should last a long time and if you ever sell the Sunfire, you can put the Sovteks back in. I can only see the price of NOS Amperex going up so either keep them in case your next pre can use them or sell them.

Buy from someone reputable. "Sometimes the cheap comes out expensive." That happens alot.

I've been using Siemens CCa's(from the late 50's-early 60's) for a number of years(six in my CDP, lately), because of their transparency, frequency extension, bass accuracy and sound stage abilities. The CCa was a specially selected 6922 family tube, chosen for low noise, long life, low microphonics/transparency for the German telephone, telex, and telegraph services(VERY picky). Many of the German telephone hubs used tube equipment and for telephone equipment you want a "noise/coloration-free" environment. Very much worth the effort to find, and every penny spent, for the sonic rewards that they present.
Telefunken, Lorenz, Valvo and Phillips all had selections for the "German and Dutch Post" also.

I second the EH 6922. They are much better than Sovtek, cost little and in my experience greatly outlive most NOS.

Rod, let me know where you can find some reasonably priced Siemens CCA's!!
