I listen to headphones for transparency and detail retrieval, the Sony's are in my opinion king. The HD800 while perhaps a better all-rounder because of their desirable bass, simply don't have the warmth and punch [slam] of the SA's. As far as the price goes, that's marketing for ya. Price something up and people find it more desirable. I will say this; the HD800 sounds more like a Sony SA than a HD600/HD650, make of that what you will.
