Great bang for the buck, but have two annoying problems.

Summary: I love this receiver. I have hardwired sound system in my living room and BOSE in the kitchen. So I can use the A+B speaker feature and have 7.1 channel surround sound (in a way) with a 5.1 channel receiver. I do have two really annoying issues that I cannot for the life of me figure out.
Summary: I bought this amp because the first feature it lists is "Bluetooth ready." Shame on me for not reading more carefully. It is NOT bluetooth ready--it needs a separate adapter. It sounded ok but I went with the 120w Harman-Kardon they have on here and plugged in a Logitech Bluetooth adapter to that.
Summary: I'm an audio visual professional and all around tech geek. I can confirm what most of the other helpful reviews have stated. This receiver sounds great, but you're going to have to spend some time with it.
Summary: The only reason I went with the VSX-821-K 5.1 Over the VSX-521-K 5.1 was because of the Ipad/Ipod compatibility. Well it is very very much useless in that feature. You can listen to your music true the provided cable but you will not be able to see video on your TV as they claim.
VSX-821 - Slightly Deceptive Features but Good Sound

Summary: The sound is excellent, slightly better than my old Yamaha receiver. Let's call it "more realistic" but the menu interface is miserable. Pioneer flat out distorts information on their advertisements. For instance, they claim the VSX-821 is compatible with iPod's Audio AND Video.
Summary: I bought the VSX821 as a budget way to get HDMI switching for my system(AppleTV.Bluray,cable box).Performs this function well.However, when you first activate the receiver you must perform some setup functions.Unfortunately you cannot do the setup thru a HDMI connection.
