“Own a variety of 12AU7 varients, but this is now my reference tube for them. The quotes from Positive Feedback are spot-on. I would add that the great sound, detail, and insight to recordings is NOT via an exaggerated top-end or presence range, but by great engineering and performance. This purchase was worth every penny and then some.”

“Great addition to my phono amp. With the OEM tube my system had a low hum. This tube elimimated it.”

“These super quiet pre-amp tubes are working out really well in a headphone amplifier.”

“This is my second attempt; my first was wiped out for some unknown reason. After 25 hours I was not prepared for the quiet ,which was excellent. {Incidentally, I put them in the inside preamp spot on my EVO200 integrated amp.] And the bass impact was a revelation, and was no comparison with the stock tubes. In addition an improvement in sound stage was apparent. Second, I have some negative impressions: Vocals have become more strident,Why? I cannot say.I am hoping things smooth out as further break-in continues. I plan another review at 50 hours. By the way,packing and shipping was first rate”

“They really are nice sounding tubes. After running for a pretty short time they really did turn out to be quiet and they sound as good as any other tubes I've tried, good dynamic range and nicely balanced in my opinion.”
