“My system is Goldenear triton 7 speakers powered by a Primaluna Dialogue Premium integrated with Tung Sol EL34 power tubes and stock driver tubes. This tube adds clarity and resolution over the stock tubes in the most natural and musically way. Everything just sound more realistic. Before installing these tubes I found myself listening in triode mode more often then ultra linear, now it’s the opposite. Love Upscale Audio, this store is a true gem. Every experience has been flawless.”

“Immediate, noticeable difference from the stock Primaluna 12au7’s. I replaced the front 2 gain tubes on my PL EVO 300 integrated. More clarity, and it is quiet - less hiss. I feel my Evo 300 is miles better now! I used the platinum grade version. Thank you Josh for the recommendation. And thank you Kat for introducing me to Josh. You guys add value.”

“Very nice tubes (in my Primaluna Prologue Integrated amp). I have quite a few pairs of NOS 12AU7s that I've picked up over the past several years from Upscale. All great. Kevin's descriptions are accurate, and I'm glad I have some inventory. These GE tubes, to me, are just clear and balanced from bottom to top. They kinda remind me of the Brimars or Seimans. BTW - I notice a bigger difference when rolling tubes than when swapping wires, but maybe that's just me (and my wires).”
