Summary: I am totally satisfied with this receiver so far...The step up from just having Pro-Logic to this 6.1 system is considerable. It makes everything sound better... music, movies, and games. Contrary to the report I saw here,this receiver has (2)optical inputs with (1)coaxial input.
Summary: This is my second 501, because the first unit died after years of daily use. I have a higher end Onkyo for a theater room, but use the 501 in the Living and its always taken care of business very effeciently.
