When I originally got my setup I got M22s, a VP100 and QS8s. I then changed my mind and upgraded to the VP150. NOT because there was anything wrong with the VP100, but because I wanted to avoid upgradeitis and futureproof my setup for when I move to a larger apartment/house. The only difference I noticed between the two speakes is the VP150 is longer. Sound quality was not markedly different.
