“These valves replaced the stock KT88s in a Prima Luna Dialogue premium, driving Focal 1008 Be speakers. I loved the KT88s, but the 120's just deliver more authority and punch. I tried the Prima Luna EL34s, which felt thin and weedy, and didnt stay in the amp for very long at all. These tubes have turned the best amp/speaker combo I have ever owned into something even better. Fantastic. As an added bonus they appear to be the same tubes that Prima Luna brand as their own and sell for about twice the price here in Australia. What is there not to like about that.”

“I replaced failing Kt88s with the Tung-Sol KT120 in my Pete Millett E-Linear SE KT88 amp. A great improvement!! More authority from top to bottom and very smooth. There was a lack of "snap" that I wanted until raised the plate voltage to about 440v. In my amp this seems to be the sweet spot.”

“My search for tubes for my rogue cronus magnum has ended.I have tried el34's, kt77's,kt90's,6ca7 treasure and finally the kt120's.All i can say is WOW !!. this is the finest tube that i have ever heard in this amp. powerful lows,crisp clean and soaring highs, they just lit up this amp like no other tubes. I am so glad that I tried the cryo version, an outstanding product.If you have a rogue magnum or any amp that can use this tube you should try them. I have never written a fan letter for a tube but these are worth it.”

“Even response along the frequency range with an extended top thatâ€:tm:s not bright. Soundstage is very good. I didnâ€:tm:t find them to be obviously more powerful, however, thereâ€:tm:s an effortlessness to their sound with a wide dynamic range that maybe tells the real story. Among current production tubes the Tung-Sol Reissue 6550s are among my favorites and to that small group Iâ€:tm:d have to add these KT-120s. Iâ€:tm:d purchase them again. (This review is based on listening to eight of them in a conrad-johnson Premier 140 amplifier over QUAD ESL-989 speakers.)”
