Looking for speaker recommendations

I retired a couple of years ago and as a hobby have become a bit of an audiophile.  I need some speaker advice from those of you who know more than I. 

I listen mostly to classical and jazz. System is on most of the day for background music.  I do more critical listen from 8-10 in the evening at low volume (50-60 db.)

Been buying and selling gear and my current system is a Mac computer, Teac UD-301 DAC/preamp, Classe CT-2300 amp, Vandersteen 2CE signature speakers. My listening space is a 20 X 18 foot living room with cathedral ceilings. Due to WAF restrictions, the stereo system is in a corner of the room with the speakers 10 feet apart, directed at my listening chair that is 12 feet away.  

The Vandys sound nice but I suspect they are too directional for my listening space and style.  I am looking for a speaker that has a more fuller sound stage and will fill the room with sound. Speakers will need to have a better WAF than the Vandys. (Wife does not like the black socks on the Vandys.)

I prefer to buy used and am looking in the $2-5K range.

My current short-list for speakers is-

Legacy-Signature SE

DeVore-Gibbon X

Any advice/recommendations would be appreciated.
