I use a Senn HD800 in my reference rig, in a balanced configuration. I am now putting together a portable/transportable system. If I decide to use the HD800 for the portable system, I will have to use a different (unbalanced) cable. That means I would have to frequently switch cables as I move the HD800 from the reference system to the portable system. I am concerned that repeated cable switching will eventually wear down the cable connector on the headphones such that they no longer provide a secure fit. Does anyone have any experience with doing a lot of cable switching with the HD800s? If so, did the switching damage the integrity of the connection fit?
