I also became a little bit annoyed at the slightly overbearing bass of my HD600s. I was feeding my phones from the headphone jack of my very ordinary and humble integrated amplifier (with a supposedly high output impedance).
About six months ago I tried replacing the foam pads with thin nylon cloth (just to protect the elements from earwax etc.). The results were as expected: because there was more treble and upper midrange, the relative amount of bass diminished and the sound became somewhat leaner and tighter.
For a couple of days I liked the sound. But then doubts started to creep in: something was missing. The sound was more detailed, yes, but also a bit hard and hollow. The wonderful naturalness of the mid-range became just too “sharp” to suit my tastes.
I ended up putting the foam pads back in place. I am tempted to think that the foam pads are there for a reason. Could their function be compared to that of the internal damping in loudspeakers?
I have tried feeding my HD600s both from the output of my no-name soundcard and from the headphone jack of a cheap cd-player (with supposedly lower output impedances). Result: the bass was again leaner and tighter.
I would be very interesting to try Corda HA-1 with its “0 ohm” output impedance. However, with the Corda it is not possible to try before you buy (please, correct me if I am wrong here). Has anyone made any specific comparisons / measurements / calculations: how much will the bass (around 100 Hz) be attennuated compared to a typical headphone jack (120 ohm or more)? I would be grateful for any information.
