This 10,000+ hour tube is known as the HOLY-GRAIL for excellent performance, smooth highs, outstanding 3-D holographic soundstage, lots of open-air, neutral timbre, true to life un-colored sonic reproduction, magnificent inner resolution and detail, and overall perfect resolution and balanced sound. Improved dynamics, smooth frequency extension accross the spectrum are immediately obvious, making the music sound much more accurate and real. A major improvement over other 6922 E88CC, voted one of the "BEST" 6922's ever made!
As proven by the Amplitrex readout the H/K Leakage (Heater to Cathode) is ZERO! (0)
Let me repeat! ZERO LEAKAGE!!! = THE BEST THERE IS!
CERTIFIED ULTRA-LOW-NOISE SPECIMENS

Tube # 4: Side 2: 20.0mA (133%) and 12,680(101%)mA/V (gm) (top code # 184) <27> between gold-pins
They are very similar to the CCa Siemens 1960's - Both the Siemens & Telefunken are #1 and #2 voted best in it's class. Sonically, Telefunken is the most neutral responsive tube you can get. There is no coloration of sound, what you put in is what you get out , exactly.
Known as THE Reference quality 6922 that is very open sounding, crystal clear and warm with a 10,000 hour + long-life, very musical 6922 that is highly recommended with excellent resolution and inner detail and accurate reproduction.
The Telefunken do hold their value and the Siemens do too, so it's just 2 of the best there will ever be made! I don't know what more to tell you. You would have to compare them yourself, on your system, as everyone has different components and ears too! If you love ALL your other Telefunken <> Diamond tubes, then you'll love these!
Come matched and balanced with matching serial numbers too!
Choose 1 for a pair or choose 2 for the QUAD.
Actual pictures and actual test results too....enjoy!
