100+ Head-Fier
i just got the a2000z. while the resolution is very good, clarity and instrument separation awesome, sounstage very large, the bass is definitely lacking. these cans just don't play as low as the a1000z. bass is still a bit better than w5000 and so is the clarity and resolution. soundstage is similar. have a listen to them if you can, maybe you'll like them. i think i'm returning mine as the missing bass sucks and i won't be getting the a1000z either as i wanted something super high res - the a1000z is unfortunately not.
