M50 has excellent soundstage and imaging for a closed can IMO. But Shure SRH840 is in a class above - it can do everything M50 does, but better. The biggest difference is in the treble - the Shures have a very natural, refined and open sounding treble like that of a good open can, while M50 has a thin, metallic treble that lacks air by comparison. Also, SRH840 has much better textured bass and mids with a lot more micro-detial. I never heard AD700, so can't comment on those.
