“I installed Gold Lion KT77 tubes in my Primaluna Dialogue HP Integrated amplifier a few weeks ago (replaced the stock PL el34's). I am very impressed with the sonic improvements to my system- deeper/wider soundstage, smooth mids, extended highs and lows. Definitely one of the best upgrades I've made! Great tubes and great service from Upscale, as always.”

“I wanted to improve the midrange on my Premium Luna Dialogue Premium + Golden Ear Triton One setup. After a couple week’s listening time, I strongly prefer these over the KT120s I previously ran. I really like this setup paired with the Brimar CV4003 on the input stage.”

“Swapped these into my PrimaLuna Prologue Classic in place of the stock, PrimaLuna EL 34s. A month into the swap, it’s been a significant upgrade as per my preferences — The EL34s were “very nice”, IMO, but these KT 77s add noticeably better dynamics...bass”punch” and other hard-to-describe improvements on top of everything the EL34s did right. The SQ has gone from “very nice” to “downright addictive”. There is a very small and not objectionable “forwardness” with this combo that I’ve noticed when listening to 1980s, mono Beatles CDs that were ripped to iTunes at the higher “CD” rez but this is the only time this tendency, which some reviews of the 77s on the web allude to, has been apparent to me. Highly recommended!”
