I don't know your budget, but these three videos are a series of sound demo comparisons of bookshelf speakers circa 2500 Euros. Now I totally accept that you can't assess absolute quality from a youtube video, but what I firmly believe you can do is hear
the differences in tonality and overall presentation of speakers when they're demonstrated as in these videos. That at least may allow you to automatically discount certain models. It does require some skipping between sections of the video and between videos granted (they talk far too much in my view, but it's a recording of livestreams so I suppose it's to be expected).
Anyway, I hope you find them useful:
