Ditto, Pops. Mullards put the 14 at a level I feel only the 16LS can beat. Our 14LS is running selected, matched pairs and was compared--at length--with the 6922/17LS. It was no contest. With gain at 99, you have to have your ear next to the Avalons to hear any tube noise. Mullards are far superior to GE, Sylvania or any other 6GK5, all of which I tried. I also found Sovtek 6922s weren't the answer in another preamp. They're undoubtedly used widely because they're readily available, quite reliable and cheap and, in many applications, apparently provide acceptable response. As for milspec examples, of which there are three or four grades priced accordingly, I have no direct experience, so can't say all 6922s are undesirable.
