Summary: I was thrilled with how good the sound was for the first week I had this receiver until it locked up with the message across the screen prtection mode, I contacted sony and went thru all of thier steps to try and fix it myself and when they didn't work they said I needed to take it to an authorized repair center.I got a quote for the repair estimate and they wanted more to diagnose it than it cost me.
Summary: I have bought 2 of these sony 825, and in living room and one bed room living with Bose speakers in bed room Polk Auto I have never heard anything that sound this crisp sharp with some punch from Sony powerd SAW SUB plus I have a ACOUSTIMASS 5 on the rear channel. I also have 2 STR-DE 501 THER GREAT TOO.
Summary: The STR-DE825 has 5.1 not 7.1 surround. It has outputs for 2 front, 2 rear and 1 center (5.1). The other (B) outputs are for separate speakers and do not operate with (A). Overall, the unit is far too complicated for the average listener and lacks bass punch.
