Awesome to hear the XBA-4's did the same thing to me. You'll be happy with the M7's as they still have that same (but improved) sound signature
I haven't tried any aftermarket cables with the M9's, mainly because I don't want to wear out the mmcx connector. Sony seem to make their mmcx connections really weak and i learnt that the hard way with my XBA-Z5's.
