Magnepan unshielded – should I be concerned?

Since owing the mini Magnepan desktop system I have pretty much lost my desire for listening to headphones, but then I read in the planar asylum a short discussion as to the potential hazard on nearby external hard drive and computer as a result of the Magnepan being unshielded. 

I reckon it was referring to the effect of electromagnetic wave generated by the Magnepan on sensitive electronic equipment.

Appreciate advice on these concerns.

I have 40lb TAD compression drivers fairly near my computer and have had no issues compared to the massive mag field in those  a maggi with it fridge door style mags shouldn't be a issue.
