Sony PS3 Output Plug
 

Iam trying to find one for making my own audio output cable.

Does anyone know of a source?

Cutting a made up one as a connector is the ultimate solution if I can't find one.

The PS3 plays SACD with some transparency, and much better than some universal players.

if you can't find one, remember the PS2 uses the same plug and they may be considerably cheaper (<$10 in some cases)

Also, there's an optical spdif out.
