high price tag coupled with a rare discounted headphone changes its sonic presentation.  not... it reinforces to me that public perception plays a huge factor on impressions, which are driven in part by current trends and reputation.

The K-1000s haven't really impressed me at all until i heard them on foo_me's rig, but the "proper set-up" should conceivably work for most decent high-end headphones especially when the other components enter the high-end, money no object range or whatever it takes to make it sound phenomenal.
