Can someone give me a rundown on the differences between the Lexicon MC-1, DC-1, and DC-2? Assume fully loaded and v. 4.0 software on all. I had pretty much been sold on the MC-1, but am hearing that it's the exact same unit as the DC-1 except with a few more inputs. If I don't need the inputs specifically, I could save 1k+ and put it into nicer amps, etc., etc. So what's the story? Also, with getting a 5-channel amp and 2-channel amp, is it best to put the 2-channel amp on the fronts, or does it matter (assuming same wattage all the way around). Thanks much!
