That's a pretty dicey way to assess speakers, by Youtube vids. Like trying to assess how a car drives from a commercial.
I am appreciating the Wharfedale Opus 2-M2 Speakers that I furtively longed for over the past several years. Finally spied a pair and went after them. Success! Oh, yes, the soft dome 3" midrange IS as lovely as I remembered! No doubt, it's own mix of characteristics, but quite beguiling. I am content at this point, given all the large dynamic speakers I have used, to hold this pair of enormous bookshelf speakers (along with quite capable subs either in the form of the bass module of the Aspen Acoustics Lagrange L1 (preproduction model will give way to production model soon, to be reviewed in owner's review at Dagogo.com), or the Legacy Audio XTREME XD Subs (also reviewed and owned) as my large dynamic speaker system.
Tannoy gets a lot of eyeballs, but Wharfedale, too, is a venerable speaker maker following tried and true principles and excellent build quality. I have seen very few companies show the extensive pages of measurements in the Owner's Manual of the Opus line speakers. Imo, you need to finalize how much of the boxy coloration you want, much of it with the Harbeth, and not so much of it with others. So, if by "organic" you mean boxy colorations, then perhaps think about whether you want to eliminate much of that. Imo, box resonances are not organic to the music, but actually an artifact added due to design choices. YMMV
FYI, if you pursue Wharfedale, you will want to look at the speaker posts in the back. On the Opus models the speaker posts are splayed wider than normal, so the leads from speaker cables must spread further. There are some speaker cables that might not do that easily. It wouldn't stop me from ownership, but it could be a frustration if not prepared.
That reminds me, I need to try the alternative configuration of jumpers, or even doubled up jumpers along with doubled speaker cables sometime! One never knows the superior outcome until the system has been built. Presumption often leads to underperformance.
