“Amazing!!! I just added these to my Jolida 3502S. The bass came in so beautifully. My sound stage seemed to double. I have the marriage made in heaven with Mullard 6201 driver tubes and Gold Lion preamps. Highs are magical with the mids adding beautiful color. All of my music sounds new. Don’t cheat yourself”

“Over the years I have bought a variety of tubes and of all of the tubes that I have bought the best quality bar none is from Upscale Audio. These KT 150 tubes that I replaced KT 120’s are even are better than the 120’s. They open up and really made the Prima Luna Dialogue Hp Integrated amp I bought from Upscale sound fantastic. I am driving very difficult Speakers, B&W 803D’s and now they sound the best I have ever heard. Every once and awhile I think I should buy something on ebay cheaper sanity comes back to me for the small difference in cost to purchase from Upscale Audio is a no brainer. They just are the best quality and have terrific service, for a Canadian to get products from California quickly is a plus. It makes listening to good equipment even better when you put the best tubes in your components.”

“The KT150 is a great sounding tube with plenty of punch, detail and air. Be forwarded that they tend to be microphonic and I think the manufacturer's quality control leaves something to be desired. The pair I ordered from Upscale are relatively quiet however one does ring slightly and is tamed with a light grasp on the glass envelope.. The pair they replaced rang like bells. Also, one of the pair I ordered arrived DOA with the silvery coating inside having turned white indicating the vacuum had been compromised. Upscale Audio's customer service was excellent and the tube was replaced without a hitch per their policy. All is good now.”

“The KT 150 is probably the best modern power tube, not quite as good as NOS 6550 but so close in tone across the frequency bands with power to spare!”

“I have only used high quality KT 88s on my Margules Black amp so far. Unsurprisingly, I was a little unsure, even apprehensive, about the move to KT 150s. But these tubes have worked fabulously over the last month. Also, Thom and Tamara at Upscale Audio were super efficient and helpful: thanks again.”

“Switching from the EL34 to the KT150 brought my excellent Primaluna Dialogue HP Premium Integrated amp to a whole new level of detail, slam, dynamics, and better control of my XStatic electrostatic speakers. This is an excellent mating of tubes and electronics to reproduce my source music (Tidal) gloriously and realistically. Thank you and your team for your excellent help and guidance.”

“Replaced the 6550 tubes with the KT150s in my amp and wow, wow, wow! This is not a tweek! A significant upgrade is a better description. Thank you Kevin!”
