It just so happens I have M22s and M60's hooked up right now on my receiver and switching A/B between them reveals how much more articulate the M22's are than the M60's. It really is very noticeable. As Alan said the mids and highs on the M22's are more crisp and clear, the M60s are warmed up by the extra bass they put out and the Mids and highs are not as forward. With the M60's I have found the vocals on certain cd's take a back seat, so to speak, to the music and vice cersa on other cd's , but the M22's always put the vocals to the front. When I don't switch between the 2 I find the M60's very easy to listen to, still very clear, fuller and richer sounding; when listening to the M22's I find myself listening more critically for the missed/muffled sounds, high points etc.
