Agree the very affordable for many KEF ls50 is not up to all the tasks people might expect given all the rave but often not very comprehensive reviews.
From an ’audiophile" perspective, use the little guys properly though within their limits, with a subwoofer and with an amp suited to drive them properly and then they can live up to the "giant killer" billing, but of course all that will add some cost but still provide very good value for the world of "high end audio".
I recommend them highly. The little dudes look very cool, can do what they do very well indeed, but cannot do it all.
For a bit more the new KEF R3s are the real deal as reasonable size stand mount monitors go and capable of doing most of what most will ever need similarly very well ie sub is way more optional and those will probably sound better with more amps.
