Anthem MCA series I and series II differences? (1 Viewer)

There are enough differences inside besides power increase to justify the extra cost - larger power supply, higher operating voltages (and necessarily larger heatsinks and chassis), but it sounds better even at low levels since the biasing is deeper into Class A and there's less crossover distortion (crossover distortion goes up as signal level goes down).

Unfortunately, the taller chassis and greater heat makes it more difficult for me to fit this amp into my rack, not to mention the higher cost.
