i wouldn't buy a v6, dt250, or any other pads for the cd900st. for me, they degrade the sound too much. i used those pads i mentioned before and it sounds really wrong.
We can order all parts for the CD900ST at soundhouse website. we might need to have a 'buying service' like whiterabbitexpress to get them though, which adds to the cost.
also, any idea what is the driver size of the CD900ST? is it 40mm or 45mm? Thanks.
