I currently stream movies from my NAS via my PS3 through my current Denon amp. Reading the review on the 1040, I'm not sure whether this machine is capable of streaming movies as well as music or just the latter?
Just the music. You have to look further up the Sony range to find an amp that can natively stream video. Even that is rare, few amps do this. So you'll be sticking with PS3 or other device.
