[QUOTE="Jeremiah25, post: 3590090, member: 570469"] I have never owned or tested the original M1. So I can't really comment on that. I do know, however, that the bench tests performed on SP weren't done on a real test bench. They were done with a resistance load and a DMM, so distortion levels were not taken into consideration during the test. That is partly why the power levels are so high in that test. Just like my test in the car with a DMM and a clamp meter. I got considerably over rated power at the reactive load, but it was WAY over 1% distortion. I think DJ rated this amp pretty honest. He didn't really try to over rate, or under rate it. Just tell people what power it makes, and sell it at a good price. He naturally under rated it a tiny bit so that all of the amps will make at least rated power, but we are talking about a small margin. As far as low loads go.......I don't know. Haven't tried dropping it down yet, and I doubt I will. DJ told me he had them put a pretty stiff protection circuit in the amp, so that it would be reliable. He didn't try to aim the amp at competition, where low ohm loads, low voltage or excessively high voltage is prevalent. He just wanted a good daily driver amp, with good crossovers. Something that will sound good, and last a long time. To duece212, all amps that I know of make more power at 5% distortion, than at 1% distortion. You are right about that. Alot of people have misconceptions about distortion percentage though. Even if an amp is rated at 0.001% distortion, it will still produce a signal that is 5% distorted, if you push it hard. Take the cleanest SQ amp in the world, turn the gain up all the way and the head unit up all the way, and it will probably be quite a bit higher than 5% distortion. Most manufacturers rate their amps honestly at 1% distortion. They do this for 2 reasons. One is because that is the CEA standard.
