I've used Siemens and Telefunken, but for different applications. Both were excellent. The Siemens was ECC88. I spent quite a bit on these tubes, but the improvement was by far one of the most cost effective improvements I've made in the system in a long time.
The NOS FAQ section Ben Campbell is likely referring to can be found at Audioasylum.com..go to tubes section and from the upper left hand corner you'll get to info on NOS 6922 and variants.
Both tubes are fanstantic tubes, just different sounding. The Siemens are transparent, extremely detailed, airy, with a tight bass. The Telefunkens are warm, rich, transparent, naturally detailed, with a softer, more rounded bass. In the right system, either would be beautiful.
fletchj is absolutely right in my opinion and rch10 at IBM probably has never heard what tubes can do. Cheers,
