I know there is a "very slight" difference in price, but if I understand it correctly, the Mc2KW amps from Mcintosh are rated at 2000 watts and can be run on a standard 15 amp circuit. Why the need for the 20 amp on the Emotiva? I tried looking but haven't been able to find anywhere that says that the Mc2KW requires a 20 amp line. Just curious how a one company can accomplish it and another can't. Can't imagine that's where the price difference comes in.
