You probably ought to audition some Axioms.
From what I remember of the Polks and Bostons I've heard (perhaps the big Polk Lsi excepted), those speakers do not have the high end resolution of Axioms, B&Ws, and many other "audiophile" brands.
If you like the boxy, pleasantly warm sound of Polks and Boston, you may be shocked by the Axioms.
Maybe go try listening to some other bling-bling brands if you can't find an Axiom owner near you. People here are pretty familiar with most brands/models.
Or roll the dice and order some M80s.
