Summary: For the benefit of other greybeards like myself who may still want to be able to play their old vinyl, I should like to add that of the STR-DG520, STR-DG720, STR-DG820 and STR-DG920, only the last-named has a phono input! UPDATE 2014 Five years down the road, mine is still performing well. There is one glitch, which manifested itself a few years ago: the display showing which speakers are in use shows speakers which are not if fact in use — for instance, subwoofer.
Summary: I bought this receiver to replace a 10 year old Sony Amp that finally went dead. For the money you can't beat the features and sound quality. Set-up is a breeze with the on screen GUI option. I immediatly programmed my Harmony One remote to work with this receiver. The remote that comes with this thing is big and bulky. My only other complaint is the volume response is slow. It takes awhile to turn up or down the volume. No real big deal.
Summary: For the price the Sony STRDG920 is one of the best middle of the line A/V receivers on the market today. It meets most peoples needs and with its on screen display, installation and set up has never been easier.
Summary: I went ahead with the Sony DG920 because it offers upconversion on several of my components as well as running the audio output through the HDMI line. Unfortunately Sony has discontinued this model, it serves my purpose for my main A/V setup. Unless you are running multiple speaker setups, this receiver will fill your needs nicely. It's easy to use, once set up, and delivers clean,crisp sound for the price. As usual, Sony delivers quality.
Summary: The receiver works ok overall, but it does have one problem that worries me. When I pause my DVR for more than a few minutes, the tv picture becomes blurry - the problem only goes away by restarting the A/V receiver. I just bought this a couple weeks ago - is this an omen of bad things to come? Only time will tell.
Summary: Most of what you need to know about this AV receiver has already been discussed in the other reviews. The receiver has a very good set of features for the price point, which was the primary reason for our purchase. Without getting into the finer points of AV sound options and HD video conversion, this unit fits the bill in our family room and kitchen - a busy, noisy place with teenagers and a couple of dogs.
Summary: Purchased the 920 and have it hooked to a Blu-ray player, a Sony 400 DVD/CD player, and an old VCR-DVD combo. Speakers are Bose. TV is a Sony. All hooked up via HDMI. Video and audio quality are excellent. The only thing I haven't got figured out is how to make it so the volume level is constant between different cable channels. Sure beats my old antenna CRT television...
