100+ Head-Fier
I've owned both the HD600 and HD560II. For me, the HD560II is clearly the better and more faithful headphone, without any doubt. HD600 has some upper bass colouration although they're more neutral than the HD650.
HD560II displays a poorly mastered recording exactly how it is; crap. HD540 does the same; it's just more spatial IMO.
