i have the KT120 tubes in my Rogue Audio Cronos Magnum (earlier post). The KT120 tubes really did the trick as well with the exact same effects you described in your article. I called the guys at Rogue to get the KT120s to replace the KT90 tubes that I had been listening to for almost a year. They mentioned to me that they might start offering it with KT120s as the standard tube in the Magnum. As of when I talked to them, every single person that tried the KT120 preferred it over the KT90s. The Cronos Magnum with the KT120s offers a whole lot of music for the buck.
