I got FIIO RC-SE1 cable on Friday and it's okay. The cable is sturdier and don't get tangled up so easily, but there is also more microphonics. I can't say much about SQ since I haven't been ABing, but it's definitely not worse than with stock cable.
The cable has been precurved with some plastic over the cable, but it's almost indistinguishable. Not bad for 28€
