Thanks Kenan for the info. I don't have time to read the whole thread now but I bookmarked it for when I can. I don't seem to have the center channel clipping some people there describe, but some others talk about the "sibilant S", so that would be one way to call it. One thing I'm sure is that this is not a problem with anybody's receiver, Denon or not, and mine is a Pioneer anyway. In fact is a Pioneer that sounds better than any other receiver I've ever heard and that includes some costing ten times as much in show rooms. One thing I can say for sure, this is a Netflix problem. I never heard this "sibilant S" in any other movie, TV show or music, from any other service, disc, TV, etc. I don't know if the DD+ that Netflix uses is a bad technology, or maybe the guys they have doing the encodes don't know how to use the software or hardware properly, but it's their fault anyway.
