AX2000 vs AX2000HC

[egor65 0]

What makes a AX2000HC worth $1000 more than a AX2000? I know that volts x amps = watts. I have been told that a AX2000 produces 600 watts at 4 ohms and that a AX2000HC provides 150 watts at 4 ohms. I don't understand. Does the High Current amplifier have a extremely low voltage? Does the AX200HC have a much better power supply contained in the same size package? What IS the difference? I know from experience that US Amps builds a heavy duty amplifier, but specs don't help me understand what I am getting for my money.

Greg would be better suited to answer this question, but I think the HC model is by custom order only now.
