Who knows if it is important 
But on 252 & SC, the signal goes through the burndy.
There is conflicting info on what is best. Richard says close but no touch, others who usually know say touch in one point only, some dealers even wrap them once …
There is discussion and pics here (link): Cable dressing guide for Naim
and elsewhere if you search for “burndy snaic touch”
I suppose I can easily try no touch vs one point as it’s just a matter of moving the snaic a bit (compare JimDog’s pics above, mine is the same except his nearly touch but don’t, and mine do)
