since you seem to be concerned with whether it's a audiophile speaker, perhaps you should listen to a bookshelf speaker of a higher class - e.g. see list >>
such as Dynaudio Special 40, JA Prism, Harbeth P3ESR, Totem Signature One, Amphion Argon3S, Buchardt S400, Perlisten R4B, etc. to decide if there is a significant improvement FOR YOU. My guess is that there will be and you will want to explore it further if you can be happy with the LS50s, long term.
