“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.”

“These are terrific tubes in the gain positions of my Primaluna Dialogue Premium amps (used as monos). The soundstage size and depth is exceptional, the bass is deep and very detailed. Extremely quiet with oodles of unforced texture and detail. Front end is PS Audio DSD (with Sunlight firmware-amazing) and BHK preamp. Speakers are Usher Audio Dancer Mini Twos with three REL S-5s.”
