Summary: I replaced on older Denon model with this receiver about 4 years ago. I decided then to that because I got a great deal on a used one. What a great trade-up that was. I then moved and decided to sell the old one, and purchased another used one about 4 months ago. I decided to purchase a another one because Sony's apparently has discontinued this model, and that's a shame. This is an excellent buy for what it is.
Summary: I upgraded to this Sony receiver for better speaker connections. My Sony HDTV already had the HD inputs, so the receiver having an HD output was of little consequence to me. The STR-DG510 works well for the small room it is in. It is an affordable alternative to the more expensive receivers I looked at. Sadly, it is out of production, replaced by a new line of Sony receivers. I just wish Sony could have added another set of video inputs.
