If it makes music "messed up" what is it doing to movies?
Makes them sound great. I was reading some other information about it and it seems to me that it was designed more for movies anyway. The marketing doesn't say that, but I too get odd, exaggerated reverb when listening to music with it turned on. Thus the "messed up". Alan describes it pretty much spot on that it sounds like a "hall" or "cave" mode. Even when not selected. I will have to play around with it some more tonight. Maybe it is an Onkyo thing. I've got a new Onkyo 709...
Again, open invite to come and hear what I am hearing.
