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: As all Onkyos, this is a good amp/receiver, and should give you good service until the"next" thing comes on the market. It does a lot. Two minor negatives though (or perhaps not so minor): it does not have HDMI input, and the speaker terminals in the back are so cramped, it will drive you bonkers, trying to connect all those wires. If you have a pianist in the famly, try and get him to do it for you.
Summary: I bought this receiver together with the ipod dock, thinking this would be easy and the two would work well in sync. I am not a geek, but can use basic computer, blackberry, etc and make simple fixes. But this manual is the most obtuse thing I have ever tried to delve into. It's horrible, and written for the kind of people who don't need it. The word "ipod" or "dock" never makes an appearance. Instead, it's fleetingly alluded to as "hdd" but not in any meaningful way.
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. This reciever meets my needs and performs admirably for the price, despite its modest output (70W). Super clean sound, various pre-set options, customizable speaker setup choices, etc.
Summary: I bought this on sale for $170.00 to replace a tx-sr502. The 502 was 5.1 and not xm radio compatible. Thought these were the major differences with the 504. I don't care about 7.1 since most MC is 5.1, and not a big XM radio fan. So as long as the 504 had all the other 502 features, the 504 would be fine and probably better. Not quite. The 502 would output any input to the B speakers, handy for outdoor speakers and extensions in other rooms.
