Re: Lab Gruppen PLM10000Q I'm not an expert at amp efficiency, but looking at the QSC PL6.0 it puts out 2650 W per channel at 4 Ohms, and the draw (1/8 power pink noise at 4 Ohms) is 16A. The 10000Q gives you 4 channels of 2700 W at 2.67 Ohms, with 31 amps draw. So their efficiency is almost identical.Maybe the QSC was also inefficient.
