Summary: Great value for its price. It does everything I need it to do. I use my PS3, U-verse, karaoke machine, PC, CD player, VCR, etc... One caveat is sometimes the video doesn't come up initially. You have to switch to a different input then switch back at times.
Summary: This has gotten everyday use for over 2 years, still going strong. I use it for the 4 HDMI inputs, headphone jack in front, and 2 sony speakers in front. IMHO that's all you need, and it has more features on top of that. Downsides (very minor, but here they are) - there was a very rare bug where a certain unique sound on the hdmi input would cause the signal to drop. Maybe happened twice a year. Was very strange, and only happened during a certain sound.
Summary: I'm a huge techie, but I just recently entered the world of surround sound. The reason being cost and space. Having moved in to a bigger apartment, i decided to go from 2.1 speakers to a 5.1 set-up. The first thing i looked for was a good, but cheap receiver. Something easy to set up, but still had a some bells and whistles. After searching several audio sites, i found that a lot of professionals recommended this receiver.
Summary: I just hooked this up to a set or Energy RC Micro speakers and I am amazed. Of course, the speakers are not the best money can buy but they are very nice and fill our family room with precise sound, not just noise. I am a person who judges my audio equipment not by how loud I can crank it before I hear distortion but by how much realism comes through at lower volumes.
Summary: I wanted some nice basic surround sound using HDMI. With this receiver you CAN send your HDMI into the unit and play the sound out the receiver while the video continues to the TV. Perfect. I have NO issues with any humming or buzzing or HDMI problems. I have a gateway PC, PS3 and Scientific Atlanta comcast box and i can easily switch back and forth all day long. Worth exactly what I paid for it. Very satisfied.
Summary: This review is written by my son as he uses it more than I do and can give a better review for it. His words are as follows: "As long as the THX audio decoder is not really important to you, this is one of the best and cheapest receivers you can get your hands on. Facts before opinion - you can find cheaper receivers than this, but nine times out of ten, their HDMI inputs only offer video passthrough (meaning you have to hook up a separate cable to get audio).
Summary: I won't pretend that I'm an expert audiophile or anything, had one of my friends help me hook up my system and explain several things to me, but after a few weeks of use this receiver is doing an excellent job. First one I've ever purchased and I'm using a 5.1 Jamo speaker system with it. Have my Sony Blu-Ray and Xbox 360 hooked up through HDMI and everything sounds great, plus it supports the newest Dolby and DTS codecs.
Summary: Did a lot of research and I am glad I purchased the Onkyo TX-SR507. Mostly looking for good sound with the proper connections to hook up blu-ray, dvd, game console, HDTV, etc. For the price this receiver makes the grade. Very easy to set up with HDMI cables and automatic audio adjustments to adjust surround sound for your room. Gets too hot if you have PS3 running in same enclosed cabinet but so do all the other receivers. Universal remote is better than most.
Summary: I bought this receiver to replace a 6 year-old Sony that did not have HDMI input, and could not decode DTS. It fit the bill - with most A/V components now running HDMI, the 4:1 switching feature cleaned up a lot of cabling and source switching complexity. What I didn't expect and was delighted with, was the overall improvement in sound from my old receiver. I have a mix of speakers and a layout that fits my living room, but is not ideal for surround sound.
