I've had two dual rectos (a 2 channel and a 3 channel) an early Mark IV, a TriAxis/2:90 como and a DC-5. In my opinion, the 2 channel rectos smoke the 3 channel rectos hands down. Whether you have a 2 or 3 channel recto, your clean channel is going to suck either way. A lot of people argue that it's not that bad, but it's one of the worst clean channels I've ever heard on an amp in that price range. So, let's forget about the clean channel and move on to what the amp was really made for. The 2 channel rectos are much tighter, smoother, and sound more organic. I originally had a 2 channel recto, bought a Mark IV, and then sold the recto because I never used it after getting the Mark IV. About a year later though when my band at the time was getting ready to record, I wanted another recto for the album. So I found a good deal on a 3 channel recto on Harmony Central and snagged it. When I got it, I couldn't believe what I was hearing. I thought it had to be the tubes, so I retubed it and gave it another whirl. Total crap. I'm not knocking anyone that has a 3 channel recto, I'm just saying that you don't know what you're missing compared to the 2 channel ones. The difference really is night and day.
