So I'm looking to rebuild the home theater system

i don't doubt that arcam/anthem are much better for critical music listening, but if you're avr is just for movies the difference between the mass-market fare may not be cost-effective for you. personally, i'd go to accessories4less, which has great prices on yamaha, pioneer elite, etc., and pick one of the higher models out--you'll save a couple grand.

curiousjim, a lot of the newer avrs have wifi and bluetooth built in--if it doesn't you can add a google chromecast audio ($25), which is extremely simple and works very well
