Lots of opinions all over the net, some pooh pooh it while other praise it. I suggest you read the article linked at carey audio, it very informative then you can form your own opinion and decide if it is something worth trying. I don't have the coin to try it though I may do so one day since the M80's have the feature. A 7 channel sunfire amp is 3500 so that's a no go lol. Maybe another Emo 2 channel .

Still with using a powered sub to do the heavy lifting I am on the fence whether it would be beneficial.
