Getting a Divorce and can now buy floor standing speakers

@OP. You shouldn't be having imaging issues with your Harbeths. So the issue there is either setup/room and or ancillary equipment. The Harbeth's are tonally refined, which some people would characterise as laid back. But driven by a more dynamic amp, you might be surprised at them - especially given the kind of music you say you favour. Putting a speaker in the upper percentiles of your price range on the end of your existing amp is totally cart before the horse. So I would recommend that you review your entire setup before going changing speakers.

Borresen are known to image extremely well. Look at their X6 model ehich seems to be a very good value for miney or look at their better series. The M3 seems to be amazing but also cost at least 15x the price of the X6.

If the speakers are big enough, you can stuff the Ex into one of them!

Unless you're buying them as art I really can't imagine spending that kind of scratch on speakers. I find modest priced systems that sound good much more impressive than systems that have mounds of money thrown at them.

I agree that there should not be imaging issues with the Harbeth speakers.  I've heard several iterations of the 30s and they are all capable of good imaging.  Proper placement of the speaker and the listener and proper treatment of the room should be a priority.  Given the OP's high budget, it might still make sense to replace the Harbeths, but the first thing is diagnosing whether the speaker placement and room acoustics are the major concern.

I've heard the 30s run off some crazy expensive amps and they are certainly capable of sounding very good when driven by such amps.  My local dealer loves to shock customers with how good some small and more modestly priced speakers can sound when driven by really good amps.  He typically uses an LS3/5A variant (Falcon, ProAc, Harbeth, and the original Rogers) for such a demonstration.  This dealer only sells tube electronics, so the choice is typically a tube amp from Synthesis Audio.   He does not recommend such extrem price difference between the amp and speaker; this is just to show buyers that they cannot skimp on the amp and expect to get the most out of their system.

Among my favorite real world combinations with the Harbeth 30.2s that I have heard involved the use of Synthesis A40 (40wpc) and A100 (100wwpc) amplifiers.  The sound is propulsive and lively and full with these amps.
