The Oppo PM-1 is actually better when compared to the HD 800 as based on my experience with both of these headphones the HD 800 sounded a bit dull and recessed when compared to the PM-1 and also the PM-1 has even better track separation as the it has 'perfect' I mean perfect sound reproduction once compared to the HD 800. I do recommend you audiophiles to demo the PM-1 before you purchase any other audiophile headphones as the PM-1 is defiantly worth the investment for mixing both at home or at a studio.
It shows just how important it is to own and listen to a headphone for a while before making quick assumptions.
Because in reality it is a rather ridiculous statement you just posted.
But Oh well .. If you say so.
