So I'm looking into getting these as my first tube amp. I was talking to my cousin who is also a two-channel freak about the Crimson 275's. He said that when he was looking at tube amps he was talking to one of Conrad Johnson's techs and he asked him about the Crimson 275's. The tech said that he would like to see what a Crimson 275 looks like inside because he can't understand how the Crimson 275's can run their tubes so cool without it having some sort of circuitry in the device, making it not a true tub amp. He also said that Bob likes to color his tubes, making it not a real tube amp (my words not his). Has anyone else heard anything like this before? Or has seen inside the Crimson 275? I'm really interested in them and heard them at RMAF and thought they'd be a great entry point to the tube world. I just don't know how Bob could do what he's been doing if they weren't an actual true tube amp.
