As a rule I try to keep all speaker cables away from each other and from all the other cabling.
Also, as Liguy says, I try to keep power cables away from the rest. If other cables must come close, I strictly avoid parallel runs but try to make them cross the powercables at right angles only.
Interconnects seem to be less problematic. If I have to use long runs, I tend to keep them close together, however strictly away from speaker- or power cables. Also, if I have synthetic rugs ( real wool does not seem to matter)
I try to keep all cables off the floor.
