Summary: I've had this unit over 10 years and retired it a few years ago for a more modern hdmi Onkyo. I had trouble with the Onkyo already, but never with the Sony. I recently got it out and dusted it off to use again to set up a sound surrond system for my other tv.
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...
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.
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.
Summary: I bought the STRDE825 Sony receiver in 2000 and still haven't figured out all of the unecessarily complicated scenarios! The unit sounds OK but lacks bass punch. If you like your music in flat response, this unit will suffice.
