“Installed these in my Rogue Audio Cronus III. Very noticeable improvement in quality of sound. Thank you Kevin for the review of these tubes on the Upscale Audio website. Your review influenced my decision and I was not disappointed.”

“Excellent tube, very quiet, well balanced and extended, presents a good image in my phono preamp, a George Kaye-modified NYAL Superit. The two other tubes are Tung-Sol 12AX7s / Platinum Grade / No Cryo.”

“These replaced some Jan Philips. I'm not sure whether my old ones are worn out. But I will never "look down" upon these Russian tubes again. These may be the best that I've heard in my CJ PV-10bl. I did have Russian ones before that I had obtained from CJ, which were also admirable, but these could be better. They may be worth getting cryo'd next time.”
