I agree, but the point of this comparison was to compare. I like a neutral sound, need it for the purpose that I do, and was looking for a product that'd give me that. I enjoy various flavor of neutral as you can see (from darker to brighter), and I think such comparisons have a place I briefly listened to the HD600/650/660S. I won't comment much on them, but I don't think they compare in soundstage-anything. I was surpisingly underwhelmed.
