There are lots of speakers you can try, though some will be more keen than others to be kept far away from the back wall and sidewalls. Hoe dems a very important here because speakers are so room-dependent.
When I went speaker shopping a couple of years ago (with 52, SC, 250). I liked the PMC Twenty24 and would have bought them were it not for the competition. They were beaten to all present by Neat Xplorers and (to my surprise and in my house) by B&W 804 D3s.
Neat Xplorers or Orkestras would be a great choice if you value involvement and fun above tonal perfection, so perhaps not too different in biases to PMC. If you are not so sure that describes your taste, then a comparison with Spendor 7.2, passive ATC SCM40 and Harbeth (perhaps Compact 7ES?) will showcase 4 very different choices.
Making a shortlist of (say) 4 - 5 and getting (say) 2 comparative home dems should not be impossible, given the cost of these speakers. You may find your perfect speaker - at worst you’ll know exactly what you do and do not want in a speaker.
Given the VFM aspects, I’d budget on probably wanting any speaker or Isoacoustics Gaias or similar instead of spikes - esp if you have a wooden floor.
Finally, I know you asked about speakers only, but…
I now use NDX2 +XPSDR into 52/SC/300SDR at home, with ND5XS2 into 82/HC/250 (and Neat Xplorers) in a holiday cottage. While putting that second system together, I had great opportunities to mix & match.
Given that experience, I rate the ND5XS2 as great VFM, though the NDX2 is audibly better through 82/250 or even SN3 and improved further with a PS. Your new 282/250 (with Hicap I assume) will work well with your ND5SX2, but would really show the difference with a better source.
One way to do that would be to get a second-hand nDAC (a better DAC than is in the ND5XS2) and use the ND5XS2 as source only. That would give you a source at around the NDX2 level for not much outlay, and you could pay for it by looking at sightly less expensive speakers than you might otherwise consider.
I will be looking for an nDAC for that second system in the new year.
I hope that helps.
