“Very happy with my purchase as always. Very sweet sounding 6922 tube i put in my Schitt headphone amp. Worth every cent i paid. I would not even consider buying tube's any where else. Kevin & company are the real deal. I recently purchased a booster power supply 9vdc based on the hi praise about this product from Kevin, in one of his videos. Have roughly 300hrs. on it, powering my Wired-4-sound UDAC. Very nice upgrade, sounds awesome, much deeper back ground. More detail and defined sound stage.”

“A little more forward than the Amperex 7308, but clean, dynamic, and wonderful bass. The Lamm M2.2 only has one tube but that one tube can change the sound of the system.”

“I have not installed the new tubes yet, as I have been transforming my living room into a dedicated listening room. I am waiting for two subs, bass traps, and absorption/diffuser columns. Once I am satisfied, I will install the new tubes, and I am sure I will notice an improvement over the $25 stock tubes. I will update my review and comment on the sound in the future. Customer service was excellent and fast shipping followed. A+ rating for Upscale Audio!”

“What an unbelievable tube. So holographic, so 3 dimensional, incredible bass & midrange. So dynamic. I was immersed in the sound. It was like had jumped from a $4000 CJ pre amp to an $8000 pre. I have been listening to tube pre amps since 1970. Over the years when upgrading I have never this much of a difference in a new pre amp. I ordered a spare. I was considering buying the new 300 tube pre but not now!”

“Good sounding tube, but not a good fit in my system. Great clarity and impressive soundstage, but bright and pretty wimpy on the low end. I much prefer the sound of the 60s Siemens West Germany E88CC in my ANK DAC.”
