the weight of the new headphones is lighter which is great, but how about the efficiency?
very low efficiency is the only thing that kept me from buy a HE6 and the most intriguing thing about the LCD-X,
I'd love to get rid of these desktop dac/amps and go portable eventually.
In my experience with loudspeakers with high efficency have more 'jump factor'
I know the new phones are suppose to be light but if they have efficiency , this could be the ticket..
