Just installed the new SR6007 today....a step up from the Sony STR K660P that has served me well for 10 years or so.
I currently have Blu-Ray, AppleTV, Xbox, and DVR all running into the receiver via HDMI, then one HDMI out to my television (Samsung LN46A850S1F). The picture is good, however, I feel like it was better when each unit was running into the TV individually. While passing through the receiver, the image is much brighter (too bright) and overly vibrant. Previously, the picture seemed more natural. This is the case with each video source mentioned. I have tried adjusting video settings on the receiver (brightness, color, etc...) as well as matching the output (1080) to my TV but I am still getting an excessively bright image. I have not changed any settings on the TV since installing the Marantz. I'm assuming this the result of video "upscaling." Is there a setting on the receiver which can, essentially, bypass any saturation, coloring, or upscaling on the part of the receiver and simply allow the HDMI video signal to pass through as if the video sources were connected directly to the TV? I know I can connect video sources directly and route audio into the receiver separately but I purchased the Marantz intending to use the conveniences of multi-HDMI inputs.
In terms of sound, the surround seems very focused on the center speaker. Granted the speakers are very small and old. (Sony L/R surround and center speakers that probably came with the Sony receiver and an old pair of bookshelf KLSs used for front L/R) The subwoofer is nice though. Ultimately, the sound isn't as warm as I'd hoped. Film and television dialogue sounds very thin and treble-y and movie FX come across a bit brash. I have completed the Audyssey set-up and tried manually adjusting the speaker controls. I've also explored the different audio output presents (stereo, Dolby surround, multi-channel surround, Virtual, etc..) but haven't found much relief. Things were much more balanced before. Is this because the Marantz is bringing out all of the poor qualities in my speakers? I intend to upgrade my speakers but I guess I just thought the SR6007 would be such a massive step up from my previous receiver that, even with my sub-par speakers, things would sound much better and more cinematic.
I know I've only had the unit for a brief time and there will be a learning curve with speaker settings and a period of adjusting to the new sounding electronics but I found this message board and thought I'd post these concerns. Can anyone shed any light?
