I'm taking delivery of my new KRP-500A in a couple of weeks (
can't believe I managed to find one, maybe the last!), with some side speakers (KRP-S03s) for day-to-day use, so I don't have to fire up the amp.
As I'm going to have it bolted to the wall, access to the back's going to be bit difficult, I was wondering: Should I stick with the supplied displayport cable to connect it with the media box and should I upgrade the speaker cables to something more chunky?
Would upgrading the displayport cable make any noticeable difference to the (fantastic) quality of the picture and is it worth changing the speaker cable, as they'll only be used for watching TV...
Views and suggestions on both welcome?
