We’re not sure why you’d want to spend $1,799 on a 5.1-channel receiver with an integrated Blu-ray deck when you can mix-and-match plenty of terrific 7.1 receivers and BD players separately for far less, but hey — it’s CES and Denon’s introducing the S-5BD in case you do. Sure, it’ll do BD-Live and do two-source, two-zone audio distribution with 3 HDMI inputs and an optional iPod control dock, but you know you’re doing something wrong when you have to buy a separate amp to use the 7.1-channel analog outputs. Denon, you have made us shake our heads in confusion.
