There must be dozens of mods for the HD-600s (It is rumored that Sennheiser made these cans so they could be modified), and I'm looking for any modifications that people thought worthwhile, and also what effect did they have on the sound. I'm not going to use wood cups to turn them into closed back cans -- that much I know.
Many people will probably say to replace the stock cable, but I've already done that with a Wy Wires "Red" set. BTW, the reviews on these cables is rather mixed, but the HD-600s are one of the cans that are supposed to work exceptionally well.
Anything else, especially if it's fairly easy to do.
Of course, I won't do any of this until the s.e.x 2.1 is built and the cans and amp are broken in -- I'm not going to mod anything until I get some listening time on the stock cans.
Thanks in advance for any help/advice.
Thanks,
Jim
