Comparison to the Objective 2 Amp
This is the only non-slim amp comparison in the list, but I know that a lot of people have been asking for this comparison. The O2 is a better amp technically, with a blacker background, wider soundstage and clearer instrument separation. The C421 wins on midrange quality and portability factor.
