I sold my classe separates and bought the cronus magnum with the kt-120 tubes. I did upgrade the preamp tube. I'm using the 4 ohm load settings for my usher mini dancer 2's. Works well with the diamond tweeter. The bass was bloated and out of control until I switched to the 4 ohm settings. I like everything about it, but since i have a 28' room, I could use a little more power
