Genalex Gold Lions:

"The clarity of them is amazing to me. And the bass is much punchier than the EH's. What really got me was the overall clarity and smoothness of them though. Even the amps imaging is better. As I said I was skeptical and probably would not have bought them if that one had not cracked but I am extremely impressed so far. The EH's were good but these are a lot better as far as I am concerned. "

"...very fine piece of electronics here. In my opinion, these tubes really are the best sounding power tubes available. They are also built superbly, and the glass on these IS thick. One of the ways to improve sound in a power tube is to pump, pump and pump the vacuum drawdown as and molecules can impair sonics. Judging from the sound of these, this is one area they have focused and succeeded in. Please tell your New Sensor sales rep to keep up the development work as they are certainly on the right track to bringing back tube making to an art as it once was. For all you hardcore NOS fans, give these a try - and listen to the music. I sincerely believe you will be duly impressed."

Mullard 12AX7M Reissue:

"I placed them in the phase inverter of my vintage Fisher. The sound was instantly "right there" in the room. Everything, the cd, tuner and phono was remarkably improved. I formerly used good old Telefunkens in the PI because they seemed to offer a clarity I could not hear in the EH tubes I use elsewhere. The Mullards just plain "opened up" the sound and presence spectacularly. I'm a professional classical musician, not an equipment geek, so this is not a hallucination! Also, your quality control and fastest possible s/h could not be improved upon!"

JJ/Tesla KT77:

"WOW!! I finally got around to auditioning the KT77’s! They are simply amazing!... It’s like I all of a sudden had a much more powerful, clean, open, detailed, smooth, amplifier. Before the KT77’s the amp would clip when I had the volume knob at about 10:00 o’clock. Now it’s still smooth, detailed and listenable at 12:00 o’clock. I can’t believe the difference."

- Larry S., Colorado

Customer Service:

"...the tubes I ordered arrived and one was a dud right out of the box. I was sent a free return shipping label and even upgraded to another, more expensive EL34 tube for the same price as the 6CA7's I originally ordered..."

"Thanks for the extremely prompt delivery - I'm really enjoying the 6CA7 tubes in my Dynaco amp!"
