“Very nice tube, those Mullards. I like them better than the Gold Lion KT88's which I liked much better than the Electro-Harmonics KT 88's for my Prima Luna Prologue Two. That integrated amp has given me many, many hours of pleasure. Thank you, Kevin!”

“Restored PrimaLuna ProLogue Five back to life. Kevin's support staff was very helpful. Look forward to warming the tubes in and enjoying many more years of use.”

“I've only had these new tubes for a few weeks, and am very pleased with them in my PrimaLuna ProLogue Sevens. They were very well packaged and arrived safe and sound. Buy with confidence! I was so pleased that a couple of weeks ago I ordered a new set of signal tubes too! A warning to fellow Canadians, though: the import duties and taxes are pretty high! (Not Upscale's fault, of course, just a byproduct of their country of origin.)”

“Not impressed. Loud, muddy mids, no lows, no highs. Was hoping, based on qualities found w/ el34s, that the kt88s would carry those same traits. PSv kt88tiis blow them out of the water, as do GL kt88s. Thanks.”

“I tried all available KT 88 tubes from you guys for my MAC 275. Each had their own merits but to my ears the Mulllards stood out from the crowd by being the most musical. I listen to mostly jazz & piano is what I use to determine that. They are outstanding!”
