Easiest / best layout for Naim Burndy cables?

[Naimtheday]

As they are thick and not very flexible is it easier to have PS beside its partner or above below?
Connecting two on NDS to PS above one another difficult as into mostly enclosed shelves

Anyone got any advice please?

Conventional Naim wisdom is/was to keep the Brawn away from the brains as much as possible.
As long as that separation is possible, I doubt there would be much/any difference in SQ between a vertical stack & a horizontal layout.
It will all depend on your rack/shelf practicality, space & visual preferences.
I wouldn't overly worry about it.....Just hook it all up as best you can & enjoy the music.
