if you're looking at cables I can't recc hart audio cables enough, their modular system is nice, it lets me terminate in any way I want on the fly (assuming I have the interconnect). The cables feel nice, aren't heavy, or get in the way.

I love my HD800s i'm glad you're enjoying your pair! try some nice binaural music like max cooper his tracks shine the most to me on the HD800s because of that soundstage and imaging.
