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 bought this a few years ago and have just replaced it with a newer model with HDMI inputs. Overall the Onkyo is a good little receiver for the money but with a couple shortcomings. The lack of HDMI inputs is of course the biggest one if you want to use it for surround sound. You have to run the HDMI output to the television then run a digital output to the receiver, either coax or optical.
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...
Summary: The Onkyo SR504 receiver produces excellent, clear, high fidelity audio at a great price. It has enough power to run any speaker I have and has enough features to keep most people more than happy with its flexiblity. The price does mean there's some drawbacks though. There's no HDMI ports, and it cannot convert or upscale any video inputs.
An excellent receiver from a Japanese audio manufacture

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. It can producec clear and loud sound which is plenty for regular living room. You can control the most of all functions with its panel so you do not have to worry about losing the remote.
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. I got it paired with an infinity 5.0 speaker system and another pair of infinity for the back to make it 7.1 It is a great system. I did need to buy a meter to set the sound levels but it wasn't that hard to do.
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. I got the receiver in 2 DAYS from Amazon and hooked it right up. ALL I CAN SAY IS WOW. This amp is incredible. My Bose speakers sprang to life and there is plenty of power for the sound too.
Summary: Wow. This is one of the best purchases I have ever made. I challenge anyone to show me a top of the line receiver that can beat the quality of the SR504. And $170 bucks?!?! An unbelievable steal. I have this thing running with the Yamaha NS-SP5700 5.1 speaker system, and it just kicks. I easily have my 50-inch TV going thru this thing with full component video cables and optical audio connecting it to a digital cable box and DVD player, as well as a nintendo.
