Should I remove the cables from my rack-mount boxes, or leave them plugged in 24x7 ? I have a presonus firepod, helicon voiceworks, Roland GI-20, and Boss VF-1.

Will plugging my mic and 1/4" cables in an out every day reduce the life of the jacks ?
How about the 13 pin and 5 pin midi cables ?

My desk actually looks nicer when I unplug everything, but I imagine it would be a pain (at least for me) to replace the input/output jacks if they go.
