The old Sennheiser developers are the best headphone developers on the planet,( Old Senn>Old Stax>>Old AKG)
That's why the 540's/560's/Germany made 580's are so good.
they've the best timbre you can find in the headphones:sweet beautiful,delicate,transparent & neutral ,realistic timbre.
(someone described the HD540 Ref Gold has a"Royal-like" sound)
They just put the new Senn cans in to shame,when you comparing them(fatty,harsh,ugly sound)
My favorite dynamic headphones:
560 Ovation II
