Thoughts on Paradigm Studio 60's?

Just took delivery on a new pair of Paradigm Studio 60's. I liked them very much in the store, where I was comparing them to a pair of KEF Q7's. At home, however, they don't sound as good to me as my 20 year-old Polk RTA12 C's. The Paradigm'ss sound seems comparatively muted and boxy, while the Polk's sound is more transparent and open, particularly in the high end. I think the Paradigm's are broken in (ran them all day) and everything is hooked up correctly. I've always loved the sound of my Polk's but was looking for something a bit smaller and nicer looking. Do I need to move further up the cost curve to do better than my old Polks? Thoughts appreciated. BTW, power = NAD C370.
