Recommendation for detailed/analytical bookshelf speaker?

Hi. As it is almost impossible to find the "perfect" speaker and having to choose, I always tend towards very detailing and analytical speakers. What I love the most is having the sensation that the artist is playing right in front of me, being able to hear the instruments as close to reality as possible. I hate the "veiled", dark, opaque or recessed some speakers provide and if to hear as close to reality, holographic, microscopic means to get some fatigue after a while or any other inconveniences I wouldn't care. I can always hear music in a more relaxed way at other times with some good bluetooth speakers I have, but for the time when I can to examine music, close my eyes and feel every note playing at me as if the instruments were there, I don't like having limitations.

I've tried a pair of KEF R7 speakers (those are floorstanding), a pair of Triangle Titus 202, a pair of Pioneer SP-BS22-LR and Polk Audio miniscule OWM3 with my gear: NAD M22 V2 amplifier, NAD M10 integrated and Cayin A-50 MKII and believe it or not, the sound that I've found closer to "being there" and reality were the OWM3 mini bookshelf speakers. The highs on the OWM3 are the clearest BUT the Triangle Titus also do a very good work. The KEF R7 speakers are way more expensive than the others but I find the sound is darker than the other ones.

I've read and read forums and watched YouTube videos but I think I'm at a lost in my "quest". The last hint I read was that the Martin Logan speakers, with their "Folden Motion" or "Folded" tweeter provides quite a good sense of clarity and detail at the expense, some times, to get a "cold" sound. If by cold they mean extra detail, extra analysis, then I'm in.

So, after that long explanation (my excuses), could you please suggest me bookshelf speakers (that room I'm using is not big: 12'12" x 19'3) that could get me the kind of sound I'm looking for? Thank you very much.

Best regards,
