Looking for speaker ideas.

Onwatershipdown, I own the Unions and find them quite nice for the price. I pair them with my Vandy 2w subs, so I get the low frequencies to boot. 
Though I would disagree with your assessment of the Vanatoo's. Of course, none of the Vandie's want to be in the corner.
Addyson, it seems there is Audio Advisor and Audio Advisors. I was about to say they don't carry Vandies, but the latter does. Looks like a nice operation.
I would call them and set up a date for a long audition. They open at 9am weekdays, so you could get to them mid morning and be home by dinner.

While there are some good speakers suggested here I must throw my .02 with the Legacy Audio brand. A nice used pair of Signatures would really be nice and handle your room nicely a pair of Studio HD's with a sub might just be the ticket. I have a pair of Focus SE's in my family room and they are fantastic (no need for a sub with these babies), anyway, I liked them so well that I decided to stay with Legacy for my bedroom. I bought the Studio HD's and have been very pleased, I have the Studio's connected to a Sansui G-9000DB receiver and it's worked out great, you couldn't ask for anything more from a speaker. I listen to everything from Jazz to Rock and the Legacy have handled it all.

I would check and see how close you are to a Legacy dealer and check out the product..You WON'T be disappointed.

For a Zu competitor, check out Tekton Design. Both companies hand build their speakers in Utah, and while Zu have some models that look classier, Tekton is no fluff, all performance at an affordable cost. I have the Tekton Lore with upgraded capacitors (using ClarityCap MR). My room is bigger than yours, and my 12W tube amp can rock these things to make the walls shake, and they frequency extension is just amazing.

Give them a look, and you might be surprised just how much of a speaker you can get for $2000 with them. There are a few threads about Tekton on Agon so give it a good search. Best of luck!

I really need to listen to Tekton's. 
Anybody in Long IslandNYC area care to let me audition them?

@gdnrbob I live in Jackson Heights. You're welcome to come by some time and have a listening session with my Tekton Lore, but I won't be letting them out of my apartment! PM me if you want to set up a time. I think there is also a pair of Tekton Enzo for sale on Agon as we speak, and the owner is in NY as well.
