Stupid question on Power Cords?

My Shanling STP 80 and T200 came with stock power cords, after careful review I notice that they are OFC and have hospital grade Marinco connectors both look pretty well built however I was looking into upgrading but most of the power cord upgrade have the same components as my stock power cords. Is there any benefit to an upgrade? I know that my equipment is Chinese made so I personally dont know if they have built a good quality cord but in my eyes they look pretty damn good.

Any advise will be greatly appreciated! Thanks
