This unit is a perfect entry to give you really immersive surround sound from your favorite movies.

Sony STRDH770 is rated to deliver enough power for a small to the medium-sized room. This receiver will bring your home audio experience to a new level. Sony STRDH770 is a powerhouse of audio performance, featuring incredible connectivity and easy integration into your home theater system. I tried to connect my Blu-Ray player, gaming system, and up to six other HDMI devices and I had high-definition video and audio experience.
As a conclusion for this article, I would like to point out the main things of my research. A very nice feature of Pioneer VSX-531 is the HDMI pass through in "sleep mode" that allows your cable box to pass through to your TV for normal viewing/listening.
Both of receivers don’t have network audio player but taking into account its price that's okay. If you are thinking about the subwoofer, so there is good news for you - Sony STRDH770 has two subwoofer outputs versus Pioneer VSX-531 which has just one that.
Both receivers offer good sound and fantastic video for a home theater, so hoping that this article will help you which one you prefer more.
