Speaker upgrade help needed: 4500$ used

Like you all I have the upgrade itch and have decided that the speakers are what I want to change out next.

1. My goal is the most holographic soundstage and best imaging I can afford at this price range
2. I have no preference between bookshelf and tower speakers
3. I have no bass requirements as I currently live in an apartment and wouldn't want the bass to annoy the neighbors anyway!
4. Resale value and demand is very important, so rare/old models or companies that come out with new versions/revisions each year are out of the question.
5. My next speaker upgrade probably wont be for 2-5 years
6. Appearence isn't important, although I'd like to keep a reasonable footprint for the speakers
7. This is for a 2 channel only system

My current system:
Tyler Reference Monitors
Plinius 8200 mkII integrated
Muse model 9 Sig version 4 (cdp)
Ridge Street MSE gII interconnect
Harmonic Tech ProAC-11 powercord
Signal Audio biwire shotgun speaker cable

Current room is 14x18, but I do consulting work and move every year or two (so not shopping for room specific speakers!)

The cd's I've been playing a lot of lately:
Cyndi Lauper - At Last
Patricia Barber - Cafe Blue
Cowboy Junkies - Trinity Sessions
Paul Simon - Graceland
Peter, Paul & Mary - 1st LP
Miles Davis - Kind of Blue
Steely Dan - 2 Against Nature
Laureena McKennit - The Visit
Fleetwood Mac - Fleetwood Mac and Rumors

I have enjoyed the Tylers. They are my first step into home audio unless you count NHT SuperTwos. The Tylers were an ENORMOUS step-up from them in terms of clarity, seperation, imaging and soundstage. However, they dont get me to the toe tapping, emersed in the music state that I am looking for eventually.

My ear and audio vocabulary isn't at a point where I could say what I would like to improve upon or what in particular I'm looking for.

Speakers I'm considering:
B&W N 803
SF Electa Amator II
Merlin VSM-M
Aerial 10T
Von Schweikert VR4 JR
Martin Logan Request

any of these stand out above the rest?
any to remove? other recommendations?

Thanks for any help!
