I thought about that as well since I could see myself grab a Sony when the price drops a bit. I would think the silver plated(IIRC) Fostex cable could tweak the Sony with a little leanness and the Sony cable add a bit of lush to the Fostex. Of course one would have to trim those the Sony's connectors protrusions to test that theory. Also thinking those newer fatter looking Fostex connectors might not fit on the Sony now either without some trimming maybe.
Any difference when looking side by side down into the connectors of the SE and Fostex cables? Pin difference etc. that could explain the cutting out and maybe give something to look out for.
I remember yesterday, Gilly87, talking about moving to universal MMCX being better than proprietary. Nothing wrong with AT's connector(no cut out and dirt/moisture static noise issues) and at least if you buy an AT cable you know it will work right.
When I get home, I'll take a picture of the Oyaide, Fostex and the Sony cables. I bought the Oyaide cable over the boutique cables thinking it would have better ergonomics but I was wrong. The Oyaide cable is stiff with a hard plastic covering and feels sort of cheap although quite thick.
