“I have had alot of fun with Upscales Audio powertubes the Kt120 TungSol purchased. It was nice to have tube/valves that were already Burned in for 72hrs . Compared to my Kt88 the Kt120 have much Fuller/stronger lowend with very good Dynamics The top end has a Sizzle to the Sonic sound Chacter also , The midbody is warm inviting and a lil bit more meat on the bone than me kt88s Very Happy with my Purchase Kevin ! Thank you Kevin From -TeeJay The Stereo Bargain File (utube)”

“I received 1 kt120 that snaps 2 x 1.5-2 min after amp is turned on fairly loud and 1 that snaps at 1/5 the loudness of the other one. Waiting on a call from Josh on what to do.”

“Very musical tube for our PL Premium HP, best of the two worlds of KT150 (too taxing on any amp) and our favorite EL34. Tighter bass than EL 34 and very close to the sweetness and beauty of the EL34 mid frequencies. We switch between these two tubes for the last 10 years. Upscale does not disappoint in terms of high level of service, advice, trust and honesty. Thank you.”

“Purchased a 2nd quad of KT-120s. First quad of KT120s are still working great. But from this most recent quad of KT-120s two of the four tubes blew in less than 24 hours. I talked to customer service and sent pics. I was told Upscale does not take tubes back, there's not much margin for profit, we can send you two tubes but it's the last time. After all that, I just said forget it. I'll bite the bullet. Had I known there's no return on tubes I wouldn't have asked. So I'm using the 2 that were good and purchased 2 more somewhere else. All of these tubes are working just fine now. I don't mind saying I was very disappointed with Upscale's response to me receiving 2 tubes that went bad within 24 hours.”

“Fantastic tubes, I have had a lot of tube gear over the past few years, and I keep coming back to KT120’s. To me they sound a touch warmer than KT150’s without compromising on power. Very detailed, large soundstage with precise imaging. I currently have them (ARC matched and cryo treatment) in my humble little ARC VSi60. I could sit and listen all day. Highly recommended!”
