The 800S is a "big boy", it's simply priced at what high-end cans should cost, instead of 2-3x over. I look at `phones like the LCD-4, Abyss, and HEK and shake my head. The exception is the SR-009, with current exchange rates it's about spot-on @$3000. Is the HEK as good for the same $$ as the Stax? No. Is the LCD-4 and Abyss as good for $1000 and $1500 more? Not even close. (IMO, none of the 3 are as good as the 800S.)
Point? People need to stop buying those overpriced high-end headphones, they're only encouraging more of the same.
As someone who bought the Abyss 3 weeks ago and is buying the HD800S this Friday I have to say that (to me) the Stax 009 and Abyss play at a different level to the HD800S but are by no means 3.5X better.
One thing that remains untouched with the HD800/S after all these years, is the instrument separation which is simply remarkable. That of course doesn't mean without that you still wouldn't pick the 800/S over all of the other offerings.
Bloodborne and Battlefield 5 are gonna sound incredible this year
