“These are some of the best power tubes ever! I rum them in both my Evo 300 power amp, and Prologue Premium Power Amp. Powerful, and dynamic and rich sounding! A midrange that equal el34's and sweet extended highs, and deep clean low end response. A very low distortion tubes, that avoids any kind of "dry" response. I'm done rolling power tubes!”

“So far, so good. Bought these to solve a fuse-blowing problem with my Caryt SLI-80 HI amplifier.”

“I purchased two matched quads for my Rogue Audio M180 mono blocks. They replaced the gold lion KT88‘s Which sounded great but which, in my experience and in my system, proved to be somewhat unreliable with drifting bias. As Others have said, These tubes sound a bit rough for the first hundred hours. However, at 100+ hours they have mellowed out nicely and offer much better bass and detail than the gold lions ever did. I should add that based on one of Kevin‘s videos regarding gain tubes, I also replaced the 12 AX7s with gold lion platinum grade tubes. I’m extremely happy with the sound and cannot thank Kevin and his staff enough. They truly are the tube gurus.”
