Looking for speakers with soundstage depth


I guess that's what it's called. There have been some really nice speakers in my system over the last few years including Vandersteen 2CE signatures, Meadowlark Audio Kestrel IIs, Revel Performa M-20s and a few others. The Revels were the most accurate speakers I've owned but when I pulled my trusty old Kestrel Hot Rods out of the closet I was once again caught by there very natural and fun to listen to sound. Even though over the past four months I've had numerous "never heard tha in there before" moments with the Revels, I sold them.
What the small, unassuming Kestrel HRs give me is a 3 dimensional soundstage that none of the other speakers could match. It was also the first time I had hooked them to the Bel Canto eVo2i which was an eye opener. BTW, I'm pretty much convinced it's the coherent time alignment that contributes the effect.
So my question is what speakers under 2K (used) will provide what I'm looking for? The newer Thiel 1.6 or Thiel 2.3 might do it. Maybe something like a pair of Magnepan 12s?
My room is small but well treated. Any suggestions or should I just stop looking? Thanks.

one of the factors in achieving depth is very high signal to noise ration.

when a recording features several instruments recorded at varying distances from the microphone. it is necessary to have a very noise-free stereo system in order to perceive the gradation in sound pressure between instruments.

while speaker placement and radiating pattern is important, too much noise may cover up the sound of an instrument in the rear of the stage.

being able to hear , for example, 3 instruments, varying from 5 feet to 20 feet from the microphone will create the sense of depth and perhaps elicit a term audiophiles use, layering. when you have a stereo system capable of depth you also may hear separation as well.

thus it's not just the speaker too consider, but also the rest of the stereo system to produce a noise-free signal
Soundlab Dynassts are a Hybrid Electrostatic, i use Nord One SE NC1200 class D amplifier and the soundstage is huge, they cost me 2k which is about your budget, they have all the benefits of electrstatics, with the added benefit of the dynamic bass driver.

They are easy to set up and have Mid/treble and Bass adjustments but need a couple of feet or more behind them,

Good luck finding a pair, they are exceptional speakers, i have found no weak points except they deserve good electronics.
@timrhu - I'm with a couple of other posters - best improvements to imaging have been gained by introducing good cables throughtout the system. 

Also adding quality cone feet under components was the icing on the cake

My cables removed noise from my system allowing the components to amplify L/R channels more precisly which in turn  positioned the artists exactly where they should be within the image and expanded the image beyond the listening room walls

My listening room is quite spacous and the speakers are 8ft from the wall behind them - which helps a lot.

What cables do you have currently ?
