What's the difference between a DC-5 and Mark IV both sonically and physicaly like how it was built and all.

owned both..the mk iv is "more" of an amp...simulclass is big difference...if you are looking for more aggression..the IV gets you there-dc is simple 2 channel amp, and it smokes-check out the IV threads on this website to get a feel for its 3 channels and the tweaking-if you are a tweakfreak,the IV is for you-its simulclass features are intense
