where to go after Harbeth SHL-5

Hi all

I currently have the Harbeth SHL-5 powered by Pass 60.5.My listening space is at 18'X 12'X 7'.
Although I love the musicality of the Harbeths i'm looking for some more resolution and some more in the low end but without compromising on musicality. Any suggestions in the area of $k 10-12 new or used ? What about the Wilson Sophia 3 ?
Thanks to all repliers.
