“I couldn't be happier. They sound better than the 1962 NOS Telefunken they replaced. Thanks”

“I'll give it two because the sound was there but, I understand that some hiss from tubes is normal, although when you can hear it over the quieter passages, it's unacceptable. I literally mean over some of the music. This particular tube hissed so loud, wherever my volume knob was turned, that I couldn't stand to keep it. When I got it, I left it on for a few days and listened everyday for about two weeks and no improvement. The sound of it was excellent when the music was loud, great soundstage, but drove me nuts at the end of every track. I've chucked tubes that hissed less than this one. Didn't bother contacting them because of the no return policy, will just never buy a new tube again, or something that says it's hand picked. Think someone was picking something else that day.. I'm much happier with my Realistic Lifetime tube that I got for five bucks somewhere. VPI HW19 mkiii, Soundsmith Carmen, Rogue CM2, Acoustic Zen Adagio. Cables, room treatments, dedicated electric.”

“I'm using the Gold Lion 12AU7 in a pair of PS AUDIO Stellar M1200 monoblocks. These a definitely a step up from the stock PSvane tubes. There is a perception of a smoother and more open presentation with a quieter background. Also more linear sound from top to bottom. A slight ringing with the other tubes is now completely vanished. Definitely a worthwhile upgrade. Great service from Upscale! Thanks”

“Sure, the tubes from Upscale Audio are a few bucks more, but you cannot but a price in having the peace of mind knowing you are getting a meticulously tested and matched set of tubes! (especially the Kevins Stash tubes). I bought “tested and matched tubes” on eBay, and will never do it again. Buy from the best…Upscale Audio!”

“This is an extremely quiet tube and Kevin's Stash performs significantly better than the standard GL 12au7 I was using previously”

“I am very happy with the replacement Gold Lion 12AU7 for my Primaluna EVO 300. I can hear a definite improvement over the stock Primaluna tubes.”
