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: it is a great receiver sounds very good, this receiver have a neural system and is a excelent function by onkyo the sound it´s so clear, i really recomendate for a home theather system good...
An excellent receiver from a Japanese audio manufacture
10 August 2010
Summary: I use this receiver with my JVC Blu-ray player and watch movies almost every night. This receiver is compatible with 6.1ch format, which is common for many Blu-ray softs. TX SR504 creates really good surround acoustic environment.
Summary: This is a great receiver for home theaters the only thing it does not have is the HDMI pass through. It does however have 3 digital inputs for your audio and 1 coaxial for audio. Man the sounds so real.
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.
