Based on your list of what is important to you, I would suggest looking at Martin Logan electrostat's. If you like a big soundstage, it's hard to beat the "wall of sound" that they produce, and a lot of guys swear it doesn't get any better than tubes driving stat's (I use a Class A SS amp on mine).
In particular, you might consider the ML "Ascent". These go for around $2500-2700 used. As with any big speakers, shipping can be pricey, around $300, so a local seller would make your life easier. Additionally, the "Ascent" has a 3dB attenuator that can be switched in for the woofer if you want to spare your neighbors some of the low frequency energy in your music. These speakers don't have a huge footprint, but they are tall (64").

Good luck,
