“I love French silk pie. These tubes are the audio equivalent: silky, smooth, rich and creamy. Transformed my Cayin HA-3A into something truly special. I can listen for hours and experience true bliss. Thanks Kevin, these are a game changer!”

“Very low noise. Wonderful sound. It adds to my stereo. Not cheap but well worth the price!!”

“I replaced the original tubes on my PrimaLuna Evo Integrated. I am not going to say the new tubes are "better", but I personally have enjoyed the difference. I find these tubes to have a better range of detail and are very strong on mid range. I was first concerned that the mid range was overwhelming the details of highs and lows on piano and guitar, but as they have aged there is an elegant balance. I am so happy with them that I bought a complete replacement set for storage as these will not be here forever.”
