“Nice sounding tubes. I only trust upscale when it comes to retubing my amp.”

“Swapped out the factory PrimaLuna tubes with these as well as the GL KT 88. Super happy with the results!”

“I’m disappointed. I have tried these tubes in several combinations and the results have been from no improvement to a very unpleasant treble forward when used with the Tung Sols that I had been running. I don’t know why but they’re out of the system now. Prima Luna Prologue Premium.”

“Very happy with these tubes. I have a Rouge Audio Sphinx V3 paired with the fantastic Wharfedale Lintons. These are fairly sensitive speakers and one of the stock tubes was making a pronounced hiss/hum--audible over quiet passages. Regardless, I wanted to make sure the replacement tubes were quiet--and these are extremely quiet. What I was not expecting was the pronounced improvement in the overall sound. Just so much better all around--highs, mids, lows, and everything in between. And Upscale Audio had them from California to Michigan in two-days. Great experience all around.”
