If you frequent the internet, you probably know subjective reviews mean little when comparing gear at similar price point to the 976, processors or receivers. People hear with their eyes and what they preconceived. So prepro, and/or more expensive gear should, therefore would better than avr, hence what they heard and reported. Not always, but often the case, unfortunately. I have seen nothing that objectively suggest the 976 would "sound" better than the receivers you mentioned, if matched with the 5000.
