Charles? The 918 has to output over 120 watts(pursuant to the rating)at 1.0% distortion.
No surprise, but I did not do this test myself. See Home Theater Mag test at
HT test. Unless I am reading their test results wrong, they found that with all channels driven it hit 1% under 40 watts. In two channel it made the 150 range at 1% you would expect, but they don't say what frequency range that number came from. Wouldn't that indicate this amp has little power in reserve, and thus the bass peaks (needing 16 times the power, Alan describes) that are evading this listener could be due to the amp? Room, placement, reflections, etc, all still on the board as options.
