Pros: Powerful, audessey multieq, HDMI switching
Cons: runs very hot, older hdmi 1.3 lacks 3d support
- 7.1 channel THX Ultra 2 receiver with 130 watts per channel
- Powered zone 2 and unpowered zone 3
- 3 HDMI inputs, 1 HDMI output
- Audessey MultiEQ automatic setup
- Full 7.1 channel analog outputs
I have all sources running HDMI to the receiver, then HDMI output run to a Sony projector. I used Audessey to configure the speakers, then went in manually behind it with an SPL meter to fine tune the level settings. This was easy to do.
The Remote is large, and can be easily used to control the wide array of functions. I replaced this with a Harmony 880 however to make the process much smoother. The on screen setup interface is easy to understand and can be used quickly to tweak any settings that need to be changed.
The 130 watts per channel for 7 channels is more than enough power for my decent sized basement home theater. There is a wide array of DSP modes to direct surround, but most things sound best when left closely to their original. The THX-Ultra2 movie sound mode with PLIIx is a nice compromise between the different modes. 2 channel music always sounds best in stereo or direct mode. I have upgraded to a 2 channel Emotiva amp to run the front left / right speakers. This gives them just a little more clarity than the onboard Onkyo amplifiers.
6 years ago, the 805 was at the forepoint of new technology. It can handle DTS HD and True HD tracks via HDMI. This has been great with the increase in bluray movies. The 805 is limited by the 3 HDMI inputs however, I use a cheap 3-1 HDMI switch to get around this to some degree. The other limitation is that the 805 came out before HDMI 1.4 and 3d, so it does not support passing 3d video streams through the receiver.
The 805 is a physical beast. If weight is an indication for the quality of components, the 50+ lbs heft of everything inside this Onkyo must be great. In all the later models of the 80x series, they shaved 15-20 lbs off.
The only real negative for this receiver is the operational temperature. It would burn up in any close environment. I had to install mine at the top of my rack to keep it from heating up everything else.
Everyone who watches movies, sports, or video games is impressed by the oomph the system can put out. It can easily play louder than comfort. It lacks some of the latest bells and whistles like Dolby PLIIz and 11 channel height/width speakers, HDMI 1.4a for 3d, and the newest version of Audessey MultEQ XT32, but most of those are unnecessary or just incremental updates to features the Onkyo has covered.
