Summary: I had this receiver for about 4 years and the other day the sound went out. Not knowing there was a problem with the HDMI board I went to Onkyo's web site to get some information about maybe having it fixed.
Summary: Fantastic quality receiver for the money. Sound quality rivals much more expensive units. Setup is a breeze thanks to onscreen menus. You can spend more money and get a receiver with slightly better functionality and sound quality, but for the price this one is hard to beat.
Summary: During newyear holiday season, this receiver went on sale for about $130/-. I have missed that opportunity that time and was eagerly waiting for it to fall since then. Finally it did, of course not to $130/-, it came down to $150/-, I don't want to take any more chances.
Summary: I received the 509 receiver a day ago. The setup was fairly painless. Everything was going well until I noticed that I was no longer getting an HDMI signal from my SAT box. I did some troubleshooting and realized it was the port on the receiver that was having issues.
Summary: I have really enjoyed this receiver so far. The set-up was quick and easy because it has plenty of HDMI inputs to fit all my electronics into it. There are plenty of adjustments for those who like to really tune their system. One of the best features by far is the network connectivity.
Summary: Definitely like this item because not only do I have my Bose 141 speakers connect to it, I also have the Polk Audio PSW10 Subwoofer hooked up into it too... The price for this item was OUTSTANDING on Ebay, and I am definitely a satisfied customer.
Summary: I just bought this Onkyo 509 5.1 system, along with a set of Energy 5.1 speakers. I am very pleased with it and my wife was very impressed with surround sound that we both thought was better than a "real" theater.
Summary: 1. Setup was easy. Didn't need instructions. 2. Beautiful clear sound at both very low and high volumes. 3. Networking was easy when plugged into ethernet port. 4. Connecting to receiver via iPhone/iPad app was easy. 5. No audible hiss. No problems with HDMI.
Summary: I am no expert on electronics and this is my first reciever. I have it hooked with some polk TSI200's, CS10, PSW110 and OMW3s are in the mail. All the hookups in the back are clearly labeled and easy to find and utilize.
