Summary: I got the Samsung AV-R720 model 2 years or so ago. It literally looks exactly the same as this one, it even came with the exact same speakers. When my receiver started acting up recently I wanted to warn people on Amazon, but couldn't find it. Then I noticed this and realized they must've changed its name or rebranded it, possibly to avoid the bad feedback they were getting from the AV-R720. This was a great setup. I loved it.
Summary: The main reason I purchased this unit was for the implied compatibility with my other Samsung products (TV and Bluray). The remote lacks numerical inputs and the Anynet devise does not adequately communicate with the other Samsung components. It is also labor intensive to select different HDMI inputs on the receiver interface.
Summary: I'm yet another owner of this receiver who has experienced defective sound from the right front channel. The problem is usually caused by a defective Pulsus Technologies PS9829B audio processing chip. Too expensive (labor) to repair.
Summary: I'm yet another owner of this receiver who has experienced defective sound, first from the right front channel and more recently the left. Too expensive to repair. Poor quality to last only a few years.
Summary: I purchased this Samsung HT-AS720ST Home Theater in January 2009. In June 2011 I turned it on and the only sound I can hear is a loud static/crackling in the right front speaker. After troubleshooting the problem I have discovered that it is not the speaker, but the channel internal to the Receiver. After researching the problem online I have also discovered that I am not the only one experiencing this problem.
Summary: Two years after purchasing this receiver it started developing problems in the front right channel. Not the speaker, the channel. The problems have since gotten worse with some speakers just not working any longer. This is _not_ a problem with the speakers, there are no breaks or tears in the cone. I've swapped all of the speakers around. Its also not a problem with magnetic interference.
Summary: I use this to play sound from my computer/Xbox and to route video to the projector great quality the speakers are awesome only down fall is that it doesn't come with the extra speakers to use 7.1 surround.
Summary: I have a samsung home theatre system less than a year and a half old and the receiver failed. They would stand behind it by repairing or replacing at no charge. Searching the web, this is a widespread issue with this receiver. There is no way this equipment should fail after such a short time and samsung should take accountability for their quality issues. I had to pay $85 and ship it to their repair center to fix.
Summary: This sound system has great sound especially for out of the box. My friend has a Klipsch system he paid over $1000 for and I would say this is just as good as his minus the bass is a little softer but not enough to care as the bass is big and still hits very hard. The speakers are great sounding with very sharp High's and great Mid's. I have all Samsung components and it works perfectlly with them. They all start up together and shutdown together.
Summary: I've owned the HT-AS720ST for over a year now and to be honest, I couldn't really be happier with it. I've read some of the other reviews and I've experienced similar problems and in the long run I realized that the problems were caused by my lack of experience with it, not malfunctions in the equipment. I wouldn't say anything about using this device is counter-intuitive, but it's an intricate piece of machinery with a lot of variables.
