“We audiophiles are a persnickety bunch & those of us running tube gear even more so. It is a relief to be able to rely upon Upscale Audio as trusted source of tubes, especially given the current geopolitical difficulties and supply chain isssues. Prompt shipping & fair pricing: Thank you, Kevin”

“These tubes make music listening fun! I used them in my Decware Torii MKV and am really enjoying what I hear. I previously used Tung Sol KT-66 tubes. In comparison the Gold Lion KT-77s are a lot more open, introduce a touch more distortion than the KT-66 tubes but also are generally more lively. Lows and mid’s are more forward, also the highs seem clearer. My tube equipment further upstream is definitely darker (think Mullard NOS small signal tubes in the pre and phono stage equipment). These tubes are a very good compliment as I think the highs are a little more pronounced as well as compared to the KT-66s that presented more muted highs. The sound stage is also bigger. I do think that my KT-66 tubes were more 3D, but I’m hoping for more of that from the KT-77 tubes after more break in. All in all great tube, excellent quick shipping from Kevin and gang! Feeling pretty confident in my choice of tube and dealer!”

“I bought this single Gold Lion KT77 to replace one from a recent purchase, not from Upscale Audio. The one tube was requiring constant rebiasing, I have individual bias per tube. It did indeed take care of the issue. I am aware there is a quality issue with these tubes and I'm willing to deal with that as I truly love the sound of them. Next time I will purchase them from Upscale Audio and have them cryo-treated as I understand this not only improves how long they last but also the sound quality.”

“Tubes were shipped and arrived quickly. They sound excellent. I also appreciate the follow-up that Upscale Audio does as well as the fact that their personnel does not work on a commission basis. I never have had the feeling of being "upsold by Upscale." :)”

“My favorite power tube by far. It has all the attributes of the EL34 plus wonderful soundstage, great bass, more space between instruments. Voices more upfront. More notes, more music! Super fast free shipping just can’t be beat.”

“Haven’t had the KT77/EL34’s long enough to truly give them a proper elevation, but I like what I’ve heard so far. That brings up a question, I have a Primaluna Evolution 300, do I run it in high bais, or low? I’ve tried both, and there’s seem to be no difference. Thanks in advance for your expertise.”

Hi RP Martin, The KT77 tube should be run in the LOW setting just like the EL34tube. This will preserve the tube's life.
