I think I'm the only one who has no problems with the stock cable, the coiled one at least which I always used since the 1990s arrived a week ago
I would change it only to have some sonic improvement.
On this topic, I leave my cans playing a loop of "burn in" videos from YouTube while I'm at work.
Got them from Warehouse Deals but in mint condition actually, I guess they were barely used once and sent back.
They sounded great from the start with the A pads, but the "cooking" made them even better... Well, to my ears.
