What are your experiences with upgrading power cords on KEF LS50 wireless?

Hello ,
I’ll soon be investing in a pair of the new KEF LS50 wireless II speakers and I’m curious what experiences people have had regarding upgrading the power cables on the original wireless model or the new ones.  I haven’t had much luck finding info on this topic looking through past posts (maybe one thread three years ago) so I’m curious what owners may be able to share on this subject now.  I appreciate any information you care to share. Thanks.
