I’m going to go out on a limb and say probably not depending upon the room size. To preface, I’ve not heard the Blade or the LS50 Meta. However, I have compared my orignal LS50s to my Focal Kanta 2s in my main room. The LS50s with an Hsu 15" sealed sub sounded like toys compared to the Focal Kanta 2s which are not even in the same league as the Blades.
The room is large at around 4800 cubic feet so any smaller speaker sounds small in the room. Even other monitors like the JA Pulars struggled a bit. At any volume the LS50s were strainded compared to the larger speakers. In the small room I keep them in usually with a 10" sub they do great so YMMV.
