“I just received these Mullards, and right after installing and biasing I knew I was going to prefer them to the stock tubes in my new Doge 10 Mk3 integrated amp. Right out of the box they sounded better in every respect than the stock tubes ( which have 300+ hrs). It is awesome that Upscale has already burned them in for 72 hours and am really looking forward to seeing what they sound like after 200 hours and beyond.”

“compared to the earlier 6550 tubes in my Audio Research vt 100 the Mullard kt-88s sound a little more musical and slightly warm. Looking forward to MBL 126's in my system and how the 88's serve with them. thnx John Cocks”

“Quick service and help from my sales person. Replaced two of the stock KT88's with these and noticed a difference in the bottom end. Thank you for being there for us!”
