Sound Stage and Imaging

For $2k you will not get hiend quality sound ,you may get a good older speaker but 

any speaker over $10+ years old the Xover the capacitors start drying out

then detail and soundstage diminish as the Xover starts getting old.

I have been upgrading Xovers for  over 20 years,and BTW ,most speakers 

even $$ expensive brands many put in average parts at best rated 7-9, which I have a Big problem with I always end up upgrading the resistors and capacitors , inductors only if low quality. Check out-  Humble homemade hifi capacitor test and see what your speakers have , resistors only 2-3 best MundorfUltra, or Path Audio ,then older Mills ,Ohmite gold . Ceramic , cement type are gritty and degrade purity of sound. Duelund cast are still the best rated around a 15  ,but Waay over priced and too big unless you have the $$ , there are others not far off for much less $$ 

Speakers are only part of the solution.  Better to find components that produce what you are looking for no matter what speaker you are using.

For your budget --> dynamics, soundstage, etc --> try the JBL Studio 698

IMHO, soundstage has always been dependent on the source material.  You can't reproduce something the engineer didn't put into the recording?

Good speakers and good dac will not be enough for a natural big enveloping soundstage with a natural timbre and good imaging ...

The main element for the retrieval of spatial information encoded in the recording will be the acoustic relation and controls over ears/speakers/room ... No dac no speakers can replace this ...
