Summary: I looked high and low for a component audio receiver and finally found one! The only thing I don't like is that this gets a little hot, even at low volume. Even so, for the price I paid, I'm very satisfied. I can play my DVD-Audio and SACD's without having any problems, which is fine with me.
Summary: I had a Yamaha HTR 5250 for about three years now and it died on me. It was my first and last, I expect a receiver to last more than three years. After searching around I decided on the Onkyo. I was a little skeptic on the price and it not having a preamp out.
Summary: I bought two SR504s to setup for others who wanted good sound and convenient video switching but also didnt want to spend much. So far its working great. From my experience low end Onkyo components have incredible value and the SR504 is no exception. Very good sound for the price.
Summary: This thing connects to everything I have and then some! Very impressive for Onkyo's "entry level" product. If you are new to the home theater game like I am, start here! And buy the optical audio cables from Amazon...makes this system sound sound awesome!
Summary: Quite a bit of performance and many different user-selectable options with this receiver. I am very happy with my purchase. My (video) family / entertainment room is about 20' square, and has a 7.1 speaker setup.
Summary: This unit has all the things you need and none of the extra bs many of the others cram in. The sound quality is as good as your going to get in this price range. The only extra I wish this had was a EQ. Worth every penny!
