Post as soon as you try another receiver, hopefully another receiver with XT32..Also isn't this problem fixable with a firmware update? I know the unit is new with no support yet, but if XT32 truly is a problem can't it be fixed with an update?
I returned an Integra 50.2 due to the video stutter while the OSD was active as I need the OSD to see where the unit is set. I liked the sound of it though. The 50.2 didn't have XT32, so I hope your unit was a fluke...
I'll simplify this for you. Running auto-setup and then engaging Audyssey XT32 with Dynamic EQ=Tin/Echo sound (pick some familiar music or movies and listen for it.) It makes it really easy to hear by putting the receiver into mono mode so only the center channel plays. Turning off Audyssey resulted in crisp, clear, dialog and sound.
I have a full 7.2 AV123 Rocket setup with 2 Danley DTS-10 subwoofers. Every speaker experienced this problem but the center channel was the most noticeable since that is where the dialog comes from. The dynamics of the sound also changed and was a lot softer with Audyssey engaged.
I have the receiver packed up and it is ready to go back today. I am on the fence about trying the 5008 or just trying the new Denon. I will wait to see what you have to say about yours. My box wasn't in the best of shape upon arrival so it is possible something got jarred around in shipment, but this would be the first time I've ever had a receiver get damaged in transit and I've owned a lot.
There is a song called Savior by the band Rise Against, in the beginning it is soft music with the lead singer singing for about a minute. You can easily hear the "tinny" and echo throughout the part of the song so it may be worth trying out. It was also very noticeable with Transformers blu-ray.
I honestly think I got a bad unit, there is no way Onkyo would ship these with that critical of a flaw. I noticed it immediately the first time I fired up a movie.
