I really wish Kromer carried more brands than it does. Paradigm is nice, but I don't think they carry the power amps to back them up (well they have Anthem, which goes hand in hand with Paradigm, but that's it. H/K, Onkyo, Yamaha for receivers. Blah).
Audio-One is nice, although their retail space is smaller, so the listening rooms aren't up to par. If you're downtown though, not far from the centre of the city is Brack Electronics, who carry everything from Sony receivers up to Krell/Levinson/micellaneous exotic stuff. And they rotate their setups quite frequently, so it's always fun to stop in and see what they have.
EDIT: They don't carry Paradigm, but it's a fun spot to sneak a peek anyways.
