DNJ,

I have not tried the bigger system, but if the smaller Amico 500 is just a smaller package, than wow.

It's hard to explain in words, but the nice big open sound coming from the combo of a 15" to5 1/4 is pretty smooth. the highs were very smooth and not bitey.

Of course sound is in the ear of the beholder so to each is own, I am more of a sound quality than sound quantity so this is just my opinion.
