The Yamaha speakers (NSF packs etc) spank the current Pioneer's I've seen in stores over the last year or so.

 

I was going to say that the Pioneer you've chosen isn't capable of running with Dolby Vision (the VSX831 is slated for an update, while the VSX531 isn't)... but it looks like you'd need the next Sony up in the range to get Dolby Vision anyway...

 

Would I buy a VSX531 or a RXV483? An RXV483 from Yamaha, but it'll run you more. It's your money.
