Bookshelf speakers that renders 3D soundstage

I have one other suggestion, I have a very slightly used pair of Neat SX3i’s that are going up for sale very soon. They are flawless, have about 400 hours on them and never driven hard, always through my CJ CA150. They are in white and will go down to about 25hz as they are an isobaric design (two woofers back loaded). I am willing to sell them for $1,800 including shipping, I have all the original double boxes. Here is the link to them as the dealer I bought them from told me his customers were very sad they are discontinued. They are the best I have heard for that money. Anyhow, here is the link: the only reason I am selling is my Salk SS6M’ finally arrived.

I have to second the QAcoustics 3030i. The sound stage on these are 5 feet past the speakers left and right. The depth is ok but the width is exceptional with my Rega Elicit-R and Denafrips Ares II . I also have Revel 105M speakers and although the sound detail and clarity is slightly better, the Revels do not match the QAcoustics soundstage at 4 times the cost. The bass response is quite good on both. 

@scotman - Thank you for the recommendaton / offer. No decent recording I could find online for Momentum SX3i. Pursuit Perfect System (see below) reviews its little brother Motiv XS3 and find not really favorable when compared it with several peers. I kinda trust Terry. Hope no hard feeling.

OP said under $2K,... not sure the Focals can be had for that but if so, hard yes! The best I've found are ProAc, Tablette. There are many incarnations under $2K maybe even a gently used set of Tablette 10. The search stops here, literally throw a spooky-real 3D soundstage. Just my opinion.

No worries, was just a suggestion. Good luck in your quest.

+1 Goldenear BRX.

The first time I've ever heard 3D sound was from a Goldenear Triton speakers.  Reviews also reflect 3D imaging as one of Goldenear's strong suits, and the many very positive BRX reviews also confirm "great 3D imaging".  Also, they have better low bass than most other bookshelf speakers.  Check out the many positive online reviews.

Thank you and several others for recommending BRX which, to be honest, was under my radar but was hesitated to pull the trigger due to the following reasons.  It is a quite interesting design speaker.  Similar to Evo 4.2, it uses AMT and hence remitting quite detailed high frequency.  It has two passive radiators on sides for extending the low end of woofer response from 75 hz (-3dB) down to approximately 43 hz (-3dB) in an anechoic setting according to Stereophile's measurements.  It is quite a bit work done by the passive radiators, which demands high efficient amp power to do the trick.  The reviewers find the bass is quite weighted / nimble if the amp pushes the woofer well, which would otherwise be the opposite if the amp power is inadequate. 

The other major concern I have, as pointed by one reviewer I trust, is the midrange is a bit edgy.  Unlike Evo 4.2, BRX is a two-way speaker which does not have a midrange driver.  The reviewer finds the midrange is not as smooth due possibly to the steep transition from high frequency range handled by AMT done to low end woofer response.  On the other hand, the Evo4.2 handles the midrange quite well which I like very much.

I agree with @tomcarr 

I've been at it since 1968. The most dramatic change I encountered in the areas that you are looking for occurred when I built a room that is in part dedicated to listening.
