I switched to it and the difference was unreal. It was for sure a lot cleaner than my old amp. I never clamped it, I got it this past winter, but freshman can't have cars at Michigan State, so I'm stuck just using it whenever I go home til summer and next year. So I didn't have a chance to do much with it yet. But I would choose AQ over JL personally. I have a good friend who uses JL everything and it sounds good for sure, but sloppier in my opinion than AQ.
