Sony S590 with Denon 1913  

I've read through some posts and setup my S590 Blu Ray player adhering to most of the recommendations on here. However, the app streaming doesn't sound as crisp as the 5.1 coming through my DirecTv cable box.

Is this to be expected?

I watched Revenge (my gf made me) on ABC last night and it was incredible. Then afterward I streamed The Expendables through Netflix on my Blu Ray and it didn't even compare.

Any thoughts?
