I would think about placement, too. The 5.2 is a small floor stander. The Classic needs a stand. If you have a pair of subs for them to ride on, then you may be more interested in the Classics. If this is for a den or small room where you have nothing existing to put them on and listening will be more casual, then maybe the 5.2s. I have not heard either speaker so I probably know less than you do about sound.
