Onkyo has a diluted earnings per share of -85.72....::trying to bring topic back to 'Onkyo'::

My 876 sat on the top of an open AV stand, so ventilation wasn't an issue.
It did not shut down while driving my M80's up to ~100db (6+ ohm mode), but it did start to sound more stressed beyond that point. And by stressed, I mean that the bass lost definition, the highs became a bit screechy, and the whole soundstage became less coherent. Distortion without much added volume. Unimpressive.
At least when compared to how my LPA-1 handles the same situation, with SQ remaining clean and composed well past 100db. Peter, You make a very good argument for you to bring in a 3808 to complete your very good AVR comparisons!

Whoop!! Whooop!! Off-topic Alert! That alarm's going to get some use around here. Charles, So much so we'd need to create a keystroke 'shortcut' or add an emoticon for it. (Peter, though off topic usually adds comic relief, etc, OT on the economy could easily take on it's own life in that there are few who, if not affected directly, have friends or relatives who are much so affected.... D'OH, I just added to the OT! )

The AVR ...does not have a lot of room on the sides for ventilation, maybe 15mm each side. It has about 200mm of clearance at the back, 500mm clearance on top and the front cabinet door was left open and the AVR still cut out. Why it makes so much heat, and why it shuts down from heat are for the tech guys to explain, but even my Denon 3300 will cook a pot-roast in a closed cabinet with tons of space around it. I bought a fan for a computer CPU and spliced the wire to a 110 plug and connected to triggered output on Amp. Cut a hole in the back of the cabinet, or just aim it out the back of an open rack, and the amp will stay cool (at least my Denon did). After moving my Denon to an open rack, I removed the fan, thinking it would be fine with open sides and back. Not so fast. After a few hours of pumping the other day, it started spiking the volume knob on its own and would not stop. I did a hard CPU reset, etc, no luck until it cooled. First time that has ever happened, and this is a 10 year old AVR, so this could be the result of years of hot work. But heat will stop an AVR no matter how heavy its guts. So the fan is back. My advise: spend the extra cash on a good quite fan. I saved $ and I hate the sound the fan makes. Looking to upgrade now actually, so any computer pros in here that know a good fan that runs on 110 volts please let me know.

Thanks guys, at least in my situation I did get a small lump sum raise this year, followed by the 7% cut. At least I have a job, knock on wood. I really do need a new AVR, my 2805 is just getting outdated. I want to get a bluray player as well some day to accompany a new receiver. At least the Odysseys have a 20yr warranty that is tranferrable to 2 additional buyers.

If it makes you feel better, I'm still using an "ancient" Onkyo TX-DS575. You'll live.

LOL ! Ask Jay, he knows a special way to 'need' a new amp...

This is where I cannot make sense. If the 3808 is good for 103-105 db on the meter then it is only putting out: 95 db/1w/m 98 db/2w/m 101db/4w/m 104db/8w/1m This means that the 3808 is putting out about 9 watts before it no longer sounds good. What am I missing here. This receiver should sound good up to 115db and above. Perhaps the readings were taken at a distance from the source. If the reading of 105 db was taken at 4 metres then this would equate to 111 db at 2 metres and 117 db at 1 metre. These readings would then make sense.
