So I finally got my exk adapter.
Enables me to use cable B7 instead of the crappy stock cable with the memory hooks.
I also measured the stock cable and it has a resistance of 0.63 ohms.
Graphed it on stock and also with cable B7. (cable (stock and B7) and adapter (3.5mm -> 6.35mm and 4.4mm -> 6.35mm) are the only factors that got changed.)
Since this is a single DD, even with around 0.3 ohms difference with the cables, it didnt affect the FR. (some slight differences in the treble might be because of the insertion depth/angle.)
