“Very happy with the improvement. Watch Kevin’s video on these. They are everything he describes and then some. Using in EVO 400 power amp.”

“3rd set of 12au7 replacing original Prmaluna tubes, that shipped with my ebook 400 preamplifiier. Subtle improvement in soundstage width, and inner details. Incremental to the original rolling of the 1st set. I'll be buying the 4th set of two next month!”
