I recently purchase a Sony STR DG920. However, after all of the Booo's I got about Sony here on the forum...I returned it and ordered an Onkyo.
The Onkyo I purchased is TX-SR606. To me, at least, they sound equal. The main difference I've noticed is the video resolution/clarity.
The reason I chose these 2 receivers was for the (4) HDMI inputs and ease of connectivity.
The Sony upscales everything to 1080p while the Onkyo upscales to 1080i.
With the Sony, my attention was never drawn to the video quality. I guess, b/c it was the same quality that I had been accustomed to going straight out of my Blu Ray to the Projector.
With the Onkyo, I have noticed alot of "blurriness" in the movies. The movies seem softer overall and not as sharp. Now, it still looks good but it definetely detracts from the overall home theater experience. I find myself focused on the image quality and not the movie itself.
So, does the 1080i vs 1080p make a significant difference in general? I wouldn't think so......
Are there settings that I'm unaware of that could be changed? I really don't think so but correct me if I'm wrong.
I guess my next step is to find a scene in the movie that I can really notice the difference and then pop the HDMI out of the receiver and back into the Blu Ray directly and see if there is an improvement.
Any help would be appreciated.
