quicksilver V4 s

hi guys
how would the V4`s match up with vandy 5A`s.i currently have 2 evo200.2`s.how big of difference would there be
I have heard it driving a pair of 5, not 5A, at a dealer while I was shopping for speakers a couple of years ago. I was floored by the mid-range, especially female vocal. The bass was a bit loose. I bought a pair of 5 mainly because of that audition.
