I'll second John's recommendations for the Ascend 340SEs. I can point to a number of places where after comparing speakers in listening tests, people much preferred the Ascends over the Paradigms (170s over Studio 20s and 340s over Studio 40s) -- let me know and I'll dig up the link to the threads for you.
I'd listen to John - he knows his $#!%. Taste is always part of the equation, but I think he could tell a lot about speakers and knows what to use and what to listen for. He was just at my place yesterday listening to the 340SEs too, comparing them with his own speakers.
The Ascend 340SEs are about $550 a pair, plus $100 for the matching stands. You literally will have to go 2x that or more MSRP to get anything that near matches its performance. At least if you are looking for flat, accurate, musical and tight.
Heck, here are reviews of the old 170s (about $330 a pair), before the upgrade recent to the SEAS tweeters with the "SE" versions:
