I don't think it can put out the power specified because the home's outlet is limited. This thing really needed 2 power cords, one to each power supply.

This review (http://ultimateavmag.com/amplifiers/147/index4.html) had 6 channels driven at the same time, for a total of 221W x 6 into 8 Ohms (1 KHz), and 347W x 6 into 4 Ohms (1 KHz). The test bench could only handle 6 channels. The variac saturated, and then blew a fuse (on the variac).

For 4 Ohms x 6, it put out 2082W... so it drew probably about 4000W from the source.
