Headphoneus Supremus
Depends on your taste really. I repeat the difference is subtle. But if you are after the Concertgebouw or Gewandhaus feel then the Z have loads of that to offer - to me it is the best gear so far to present music in a concert hall-like way. If you are, like me, prefers a more monitor-like and dead accurate presentation of tones and timbres then I feel A is the choice.
So the staging is super small on the 1A? or like pro-speakers big?
