Anyone compared Premium AC wire to regular romex?


I am curious. Am getting ready to build a dedicated room, with dedicated AC Lines and was wondering if there really is a SOUND difference in the premium AC wire (Virtual Dynamics, JPS, etc.) compared to regular good ole' Romex??

Does the extra cost really go beyond just having the overall benefit of dedicated AC lines?

Thanks for the info. "Garfish"!!

BTW, what exactly is "TNNH" wire that you mention? Where can you puchase and what is the cost? (I'll probably use SOME of the V. Dynamics wire, but as my main panel is 50+' from my room, I can't afford to use more than one "run"!).
Is it possible to add another, seperate breaker box, say 20 feet away from the main panel, on the same inside wall as the main breaker??
Thanks for all the great tips, advice and input guys!

BTW Subaruguru, where can you purchase the Belden cable?
