That's a serious design and manufacturing defect and don't know if the unit needs to recall for safety reason. I finally returned both unit to Fry's and the sales mentioned that everybody knows this unit generate lots of heat but no one report it burns. The sales also mentioned that Bose won't sell open item to customer and hence they need to return the AM 10 back to the manufacturer directly.

2 of the 3 hdmi inputs were shorted out and this thing wouldn't even recognize that speakers had been hooked up to it. I sent it back. I will take my refund and remain sated with my aging, yet functioning, Pioneer receiver.

One thing I noticed when I hooked it up was the 703 was not as good....but not that bad. The bass didn't have the heft and the treble was not as delicate and detailed but overall I was impressed that it didn't sound "bad". That's when I started thinking a really good receiver might be something to consider.

It worked well for both HDDVD and Bluray, which was why I bought it in the first place. Now, for no reason at all it's stopped working, and no amount of disconnecting, switching of cables, or resetting seems to cure it. I can't get through more than 5 minutes of a movie without the unit shutting itself off if I use HDMI for both audio and video.

If I split the signal so that I use HDMI for video and optical for audio it plays through flawlessly, but that defeats the purpose of having an HDMI receiver that will decode the newer codecs. For what I paid for the receiver I want to work for more than two weeks. It could be that I just have a bad unit (it happens), but this is the second Onkyo HDMI receiver I've been disappointed with (the other being an SR674 I bought last year)so I'm done with them.

What's worse... I called Onkyo and they said that I will have to take it to an authorized service center. I've only had the thing 10 days and they would not even consider swapping it out.

Extremely annoying with HDMI based Blu Ray yet very hard to notice with standard DVDs. Amazon has been slow to refund as well. Looks like customer service has been offshored a bit too far...

Unfortunate that Onkyo failed to fix the video issue that was already in the 605 and 705 in this unit that sells for higher $$. I mean, what good are multiple HDMI connections, if you can't use them satisfactorily?Onkyo finally did so in the unit above the 805 - but you then are knocking on that $2K door and, not being a videophile, I could not justify that expenditure. On hindsight; however, I probably would opt for the 605!

Being a previous owner of cheaply constructed Kenwood, Sony, and Panasonic receivers, my ears were not quite ready for the symphony emanated from this glorious piece of machinery. Do yourself a favor and test drive this receiver at your local A/V store and I promise you won't be disappointed. Configuration of the receiver couldn't be easier and the automatic speaker calibration is spot on (for my use).

There are bad apples in every barrel, but my experience should put to rest the myth that Onkyos are deficient in heat dissipation. I've had one disappointment. I had the vague impression that the 805 would power speakers in two additional zones.

One note; however, I have tried using the receiver as a switch via an S-VIDEO connection and either my TV is too old(10 yr) to handle the 'improved' signal(?) and appears to wash out highlights, or the receiver is deficient in passing the S-VIDEO signal. Whatever the issue, the picture appears much better using the coax to the TV vice routing the signal through the receiver and out the S-VIDEO to the TV. You do need some type of connection from the receiver to the TV in order to use the on-screen menu; so, I lose the on-screen function if I want the better looking pic (or, have to switch back and forth).

However after 2 hours of operation, suddenly I heard a 'poke' sound and smokes came out of the unit when I switched it to play the CD music. It was a bad experience, and I don't know why the unit doesn't have any circuit protection and why it generates the among of heat. I already use the power surge protector for the unit and I don't understand how come switching to CD mode could burnt the unit.

Fry's advised me to buy the warranty in case it is burnt and they will replace a new one for me. I took the advise.

It has 3 HDMI inputs and 1 output. All of which are "repeaters" and do not alter (help or hurt) the digital signal being relayed through. Note the models below this do not do this.

I had the receiver in for about 2 weeks and I had to send it off for repairs. It never upscaled any image up to 1080p or anything close to it. Additionally, the display didnt work property.

beware; only the TX-SR875 has the upconversion feature. I learned this after reading the user manual that came with the TX-SR805.

Not alot of movies are in 7.1 sound yet, but it will come and when it does, this system will not be outdated. Setting it up was a breeze with the microphone.

That was not a issue for me but it will make the theater usage much simpler for my wife and dad. I do not have any heating issues at all. The receiver has 7" of open space on the top and the back of the entertainent system is also open.

It is big and heavy and does get warm, but for a top performing receiver that is to be expected. I'd buy it again... It does what Onkyo says it will do.

If you are using the remote no big deal, but if you walk up to the unit to select a component, unless you have a light shinning directing on the face it is hard to see. Would be nice to be back-lit. For the $1500 I saved by not buying the Denon I will live with it.

The spec said it is 1080p compatible, which means hdmi output only. It is not so obvious by looking the spec for the 1080 upward conversion. Also the switching time between modes is slow on the SR805.

I don't know what else I'll end up purchasing, as everything currently available has shortcomings to deal with. They all seem to be plagued with hdmi issues (dealing with hdmi issues has been a real pain in the rear to this point), or they're really expensive (cough, cough Denon). I thought my search was over, but I guess I'm right back where I started.

The section of the receiver that does this, called a scaler, is a Farajuada brand. The next model up (TX SR875) upgrades this section to a broad capability scaler and quenches this problem. Note this is only an issue with non-hdmi sources for ex.

As a bonus the SR805 would handle the newer TrueHD and DTS-MA audio codecs that are starting to show up on HDDVD and Bluray discs and would support 7.1 surround over hdmi.

If I bypassed the receiver and connected directly to the Pearl I'd get a perfectly still image. To get broadcast TV to work I had to split it up into component for video and optical for sound. This meant that the 1080i feed from the SA8300 would be converted to 720p before being sent to the Pearl.

I only listen to two local fm stations, but I was glad to find that this tuner is actually quite good, without the boomy and dull sound of lesser tuners.

This is just a first impression review since I haven't used most of the features on this unit but I have listened to it enough in 2 channel mode to give you an idea of it's sound quality.

You would really have to cross a major line into separate amplifiers to get significant improvement in audio performance. On the video side, there are some options that are lacking. The Video Up Conversion feature tops out at 720p with no option to output 1080i.

Onkyo needs to work on its customer service though. JJB

Can fix this with a chip swap or drive to the service center. http://www.avsforum.com/avs-vb/showthread.php?p=11463542 The Yamaha RX-V1800 and the Pioneer Elite X92 (wishing I chose this one first) do not exhibit the issue.

I do want to point that they also have the greatest customer service. They answer phone calls right away and emails within 24 hours, and go out of their way to make you happy.

The only issue I saw was (as noted by others) there was considerable delay in switching the inputs. But given the price that downside is acceptable to me at least. Before buying this unit I contemplated buying the TX-SR875 - I am happy I did not spend the extra $550.

If you are not hung up on maintaing the best possible viewing of your old non digital formats, this will not be an issue for you.

I can feel the heat coming out of the box but its getting dissipated very good. I am at advantage here because my system is in the home theater in the basement and the way I have the entertainment system setup - its not visible (remote works via the universal RF transmitter) so I can keep the back side open with wires showing.

It was a bad experience, and I don't know why the unit doesn't have any circuit protection and why it generates the among of heat. I already use the power surge protector for the unit and I don't understand how come switching to CD mode could burnt the unit.

It died after 1 hour. Wouldn't even power on. I figured I must have gotten a bum receiver and opted to exchange.

It will provide line output to two additional zones, but will power only one, and that only if the receiver is configured to 5.1.

That's a serious design and manufacturing defect and don't know if the unit needs to recall for safety reason. I finally returned both unit to Fry's and the sales mentioned that everybody knows this unit generate lots of heat but no one report it burns.

Old equipment does not match very well with this state-of-the-art receiver, so be careful on thinking you can get fully digital with out-of-date equipment.
