JAN Philips 6922 Low Nooise
I am using these tubes in a Cary V12 power amplifier. For this amplifier I bought a set with matched triodes. The sound is wonderful throughout the whole audible range. Bass is tight, mid definition is excellent and highs sparkle yet are not irritating. Microphonics- I didn't have a problem for two years and suddenly I did. I found that my PS Audio Noise Harvester had failed. The factory sent me a new replacement and...Audio Bliss returned.
