Yes the audio is "top knotch." But how much of that great sound is Lee's REALLY nice mixing setup, and how much is the amp? I'm not saying it's not an accurate replica, I just saying "I don't know." Which is why I also listened to the Summer NAMM videos of these amps, which seem to be more "raw," and the amps still sounded pretty good. By the way, I got the opposite impression--I thought that the Twin was closer to the tube version than the Deluxe. And for both amps, I thought that the high gain tones were BETTER through the Tonemasters--more "punchy," less bright, almost getting into EL34 territory.
