1: Sansui SS-100 (modified): Focus-A earpads. Single rockwool felt damping disc from a B&O U70 over rear of driver. Stock pads removed. Low bass and high treble to die for. Slight 8kHz peak and ringing. Soundstage has some holes. Slightly "crisp" coloration -- slight odd-order distortion in the lower treble. Extremely resolving. Very very comfortable for a planar; my RP18 physically hurts me by comparison.
2: Sennheiser HD700 (heavily modified): Use Google if you want...
This listing is for a fully working driver from an 11k S/N K1000 (I believe this is a bass heavy pair). This is from a pair I bought on eBay a few months ago to use as a DIY project. Fully tested and guaranteed functional. This listing is for the single working driver only -- no other pieces are included.
I will pack this very very carefully to prevent any damage in shipping.
Not much more to say, really.
Asking for $200 $150 shipped CONUS. International buyers...
Wow, can't believe they copied that design from Sansui. Literally exactly the same as the SS-100, just moved to the strut instead of the yoke. Not like anyone cares 40 years later, hell it could even be coincidence, but still.
