“The KT120's are far better than the original KT88. More dynamic, fuller midrange and better imaging and depth. Major upgrade. Very happy with this purchase.”

“I installed these tubes in my George Wright AU-70 power amps and I couldn't be happier. Not only do they put out more power than the EI kt90 power tubes but seem to wakeup these amps.”

“Oh my! So very good right out of the box but 100 or so hours later a very noticeable improvement across the whole spectrum of music. Powerful and detailed bass over the OEM EL34s, I also upgraded the pre-amp tubes from the OEM 12AU7s to the Radiotechnique 12AU7/6189 and picked up on subtleties in music that I have owned for years...great products and everything stated by Kevin in the accompanying videos is true and then some. Very happy with my KT120 purchase.”

“I decided to purchase these vacuum tubes from Upscale because I was intrigued by the cryogenic treatment that was up on offer. I also got the impression that your tube grading was probably a step up from most other suppliers. One thing I did notice is that the moment I started playing music through my newly re-tubed amp, there was definitely a marked improvement from my previous set. It felt as if I didn’t have to play the new tubes 100 hours or so to break them in, they already sounded tuned in. Thanks for your prompt service; I will be doing more business with Upscale Audio in the future.”
