“I installed these in the two gain slots of my Primaluna Evo 400 integrated. They sounded good right away, if a bit harsh. But after about a week, the intitial harshness was gone and they now sound wonderfully airy.”

“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.”
