Haven't tried them in a Cary product but did in a Dennis Had Inspire tube amp. I had 16 different 6SN7 tubes and tried to compare them all. Did this over three listening sessions, taking notes. In my system and to my ears, the new Tung-sol was the worst of the lot.
I didn't want them to be the worst and I'm not prejudiced against new tubes, some of my favorite tubes are new production. With them in my amp the soundstage was flattened and sounded boxed-in. Took the joy out of the music.
Tried them three times, over a couple of months, and this was my impression each time.
I've spoken to others who liked them. I know of a high-end system which won Best in Show in a major audiophile exhibition which used several of them in both the preamp and amp.
