Did you listen to the video? I think hearing it with some headphones is the best thing and comparing yourself(it is as he says one of the best sounding speakers out there though for the price), some of the best sounding speakers come from specialist brands that the mainstream wont have heard of, his top rated one has been the Vifa Helsinki for a while for example(£300 but sounds brilliant).
Harmon-Kardon are very well respected brand among audio enthusiasts, they own JBL too which you may have heard of but the H-K products tend to be more premium.
