nice link
one thing i dont understand. why do people look to buy headphones/speakers with a flat frequency response? would the response be better if it was matched against the fletcher munson curves?
actually, i've just looked at the f/m graph and the headphones frequency response seem to reflect the f/m shape so maybe its a good thing.
and good to see the hd25s match up well against the beyers ;) although they have poor high response
