Your Maggies deserve a higher end sub. I think it will give you more of the sound you want.
I never thought a sub could integrate so seamlessly as the Vandersteen until I bought a pair.
As far as the Zu's go, you will probably enjoy the 'more dynamic' sound, but I think you will need to add a sub unless you go with the Definition line. As I said, I have the Union, and they do go down low, but not way down-Though the low frequencies are well produced.
I bought the Union's because they were cheap and I wanted to have something to contrast with my Vandy 3a sigs. So, if you have a hankering to try them, why not? I don't think you will be disappointed.
