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. I prefer Onkyo products in general and highly recommend them for any surround sound application.
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.(not the other way around)These are both assignable to the input that you want. The setup wasnt bad. Actually, if you follow the manual, it is quite easy.
