I'm using the stock litz and prefer them to the Massdrop MEE Audio cable kit in any of its configuration. The ZX2 already has a high-ish output impedance that matches well with the Andros for my taste, so I'm hesitant to cable roll. I do hate the ergonomics of the stock cable though (annoying memory wire, not tangle resistant, fragile feeling), so I've been looking at getting the PW Audio cable, in 3.5mm TRRS configuration. The hold up is I'm not sure I like what I'm hearing with the MEE cable when used with the isolated grounds of the ZX2, so I unsure if I should spring for the PW cable in that configuration. But really, I've just been so happy with the Andros that I'm not thinking much about cables.
