Hi, I have recently upgraded my reciever and speakers to the Onkyo TX576 and the Yamaha NSP440 speakers. Everything works great 90% of the time however in very particular scenes in some films, and games there seems to be a slight distortion, pretty much always when someone is speaking, but only on particular tones. It almost seems like a clipping issue but even at low volumes the issue remains. Tried it both with and without the Audyssey auto setup and its still there. Tried playing with just about every setting on the reciever without any luck. Altering the treble does seem to have a mild effect on it, but its still there whatever the setting. I cant work out whether its the reciever, or the speakers or the combination of both that dont work well together. Any suggestions? Thanks!
