I'm confused, why are we comparing the Meta to the 8341A? The 8341 is a $6,000 a pair in the US and was not brought up by the OP.
You're welcome to your opinion, but I just want to highlight that it really is not useful to bring the original LS50 into the conversation. Other than sharing an aesthetic and coaxial design principle, the Meta is a totally different speaker. Might as well be talking about a speaker from another brand.
FWIW, I was not crazy about the original LS50 either (I've made a few posts about that in this forum before). They were good, but not
that special to me (the original wireless was much better, thanks to some DSP corrections).
To illustrate how different these speakers are, here's how the listening window for the Meta (blue, my measurements) compares to the original LS50 (orange, amir's measurements):

Other than similar bass contour, there's basically nothing to indicate a family resemblance.
Since you brought up the 8341A, the Genelec is the better speaker technically, but the meta is not very behind in practice (with a sub). I've had them both in my home and though I didn't do a direct comparison, the Genelec didn't stand out as being obviously better in independent listening when crossed with a sub. The only thing is the Metas's slight upper mid scoop. But the LS50 Wireless II gets rid of that scoop (at least, according to kef's measurements). You're splitting hair at this level of flatness, really.
If we compare the 8341A to the Meta based on my own measurements for both speakers, we get this for the listening window:

But perhaps a more reliable comparison would be Amir's measurements of the 834aA against the LS50 Meta measurements taken by the Warkyn Klippel NFS for
AudioXpress , since the NFS is a bit less fallible than I am =] Note that the bass contour is different here because AudioXpress used a plugged port. Above 200Hz or so the results were virtually identical to an open-port measurement.

(ignore the blip at 15kHz, that was an issue with my digitizing of the graph)
The differences are even smaller.
