well if high damping factor is what you want. i have a crown macro on here with a damping factor of twenty thousand. it will drive anything . on subs it simply will not run out of juice. i compared it to a krell kst 100 . it blew it away. i am in the process of compareing it to a krell 200s right now. the crown has more slamm so far.good luck on your quest. i have heard great things about the audio artistrys.
