AD900 (not x) vs AD1000x if anyone has an idea, also how they compare with HE-400s
AD900x has very sweet mids but sparkly trebles, the AD1000x is the most laid-back of the AD bunch (I'm not counting the AD500x and AD700x as I've never tried these). HE400 is boring and requires good amping (even then it's still boring to me). So between the AD900x and the AD1000x it's a matter of taste. And honestly the "X" upgrade doesn't change the sound sig, so don't bother going for the older AD900 as I'm afraid there might be some age issue.
