I deliberately changed the usage of nitrogen or gas to air when I posted because I couldnt bother to check if Nordost actually uses nitrogen or whatever. And I presumed it wouldnt be contaminated air or anything that accelerates corrision they would use in manufacturing.
Edit: here is the nordost blurb
The fuss over a mere technicality doesnt make a difference to the fact that Nordost chose air or that many other cable makers use foamed p.e with trapped air and or that many people feel the Nordost works better than other cables with a different construction. Not that Nordost is the best cable rather something works about that approach.
These kinda overtly fussy comments about inert air dont change the basis and principle behind using air as a dielectric, so I dont know why everybody's feeling a little too clever by half about it

hyeah:
