Summary: So my 818 no longer outputs audio on any input except when in stand by mode. The network port and usb ports are also not working. Also this unit is supposed to support 8ohms yet you are forced to select either 4 or 6... I contacted support for the issue and it took 2 days to get a call back because they are experiencing very high call volumes. When they finally called me back, the guy said I would have to take it to a service center.
Summary: Sound quality is great. Mostly attribute to decent speakers and Audyssey, but I do think the amplifier section is good. In addition to the Gapless Audio issue, Onkyo will not take ownership of a firmware issue that ruined the pass through capability. After a firmware update, I can no longer pass through TV sound when the unit is in standby mode. I went through tech support did all the troubleshooting, changed cables, etc.
Summary: While the sound is great I cannot recommend this receiver. It has several very annoying features that make it frustrating to use. First of all is the lack of gapless song playback from network devices. When Beethoven's 5th is building momentum from the 3rd to 4th movements it is absolutely deflating to suddenly have 5 seconds of silence. Dark Side of the Moon, don't even bother, you'll be either crying or ripping the receiver off the shelf.
very thin horizontal white line outputs to the screen and a green bars shows many times.

Summary: did the latest firmware, even the factory reset - like was suggested at the onkyo usa forums and nothing - i tried the tech support and like others said here - Onkyo tech support is a joke, absolutely NO help. I am really upset - what bad experience ... ----- 01/01/2013 - I know that soon or later (looking at the other reviews) someone will ask to contact askOnkyo@us.onkyo.com and describe what is wrong.
Summary: I purchased this receiver to replace a 5 year old Harmon Kardon that sometimes had HDMI switching issues. After running the XT32 setup I thought WOW, this sounds great, Video seems to be great too. After just a few weeks though I have joined the problem crowd- the receiver no longer will power on by remote. All other remote options work but power on will not.
Summary: Der Verstärker schmorte und rauchte. Bei der Einlieferung zur Reparatur ins Service Center wurde bereits gewarnt. Keine Ersatzteile daher keine Schätzung wann die Reparatur gemacht werden kann. Bisher ist auch nach 4 Wochen immer noch nichts passiert. Also weiter ohne Audio; kein TV, Video, da auch kein Ersatzgerät. Service Center kann nichts neues berichten. Nie mehr Onkyo.
Summary: Das Durschschalten der HDMI Quellen funktioniert einfach nicht zuverlässig. Mal klappt es sofort, mal klappt es garnicht. TV Meldet dann - Keine Signalquelle. Ich habe bestimmt 100 Meinungen im Internet recherschiert, welche genau die selben probleme haben wie ich, und die auch bei kleineren Geräte 6xx Klasse. Bei einigen wurde x mal das Videoboard getauscht. Innerhalb der Garantie begrenzt ärgerlich.
