“Used in Primaluna Evo 400 preamp in 2 front positions. Lush, textured and holographic without giving up detail, dynamics or bass. They do everything you hope a great tube would do. Love these tubes!”

“I purchased these tubes for back up. They are getting harder to find at a reasonable cost. I use them in my PLEVO400IA.”

“These were a disappointment in my Rogue RP7. One imploded at startup and the other three with a replacement sounded awful. Replaced the set with new gold lions and the sound is amazing. I was really surprised as I have six of these in my Evo 400 power amp and they are sublime. Not a good match with the RP7.”
