well after about 8 months of use, denon avr 990 overheated and went into protection mode(after about 8 hrs with all 7 channels @ near ref. volume and then about 1-2hr @ ref. followed by 20 mins of +5-+10 above ref.vol. with all channel driven. crazy superbowl party or maybe it was that horrible 1/2 time show) ....which i was not able to reset...lost display on front panel and all sound..
unit has been sent in for repair. i have axiom epic 80 less sub(velo 15") plus 2 more QS 8` for front heights in a 4000-4500 cu ft room....i do like to turn it up above ref. usually +5 or so on weekends for short times never had a problem...but i did just add heights(back in dec 2010) from 5.1.So with these 2 additional channels should i look @ adding a 2 ch. poweramp for the m80`s?anybody else using a 2 ch. power amp and how did it effect your sound(2.1 music and 5.1,7.1 )?headroom?any input/advice would help...thanks in advance and sorry for the long post.

You're damaging your hearing with those absurdly loud volume levels that you described, and instead of taking the warning that the 990 gave you and turning it down a bit, you're looking for another amplifier?

Enjoy the music, not the equipment.

Are you sure the amp overheated? I would have thought the Cops would have shut it down after....say.....3 hours?

Did you ever try to turn the receiver back after letting it cool when it went into protect mode?

You have a huge room which is up to 4500cu/ft. You are asking a lot of that receiver and I am not surprised you were able to shut it down. BTW if you are listening at reference level in that massive room, you won't have any headroom for dynamic peaks in Blu-ray movie soundstracks and are at risking of not only shutting down the receiver but also potentially clipping your speakers. Superbowl audio is not even demanding content.

In this huge room and these crazy volumes, you should definitely look at external amps and maybe for more than 2 ch. The typical contenders for relatively low cost amps are offerings from Emotiva (XPA2, XPA5) and Outlaw (monoblocks).
Enjoy your speakers wile you can cause pretty soon you won't be able to listen to them wink

yes i tried everything form unplugging unit,all cables removed,micro. reset and also network reset... nothing so unit sent in for repair/replacement
i think you may be right>>>> lack of headroom @ ref. may be the problem ..that and too many beers, in a larger room than this avr is designed for???unit was @ ref or below for superbowl itself,it was post game with some dvd concerts that done it...that and +5 or so above ref.....so will a 2 channel power amp do anything for headroom?? before i do any more damage to my hearing...
and keep in mind it is rare i do go above ref but @ ref i feel i am missing something(i should have paid the extra for the 4310 or 4810)

The 4310 or 4810 would have given you features. If you want power, you need an amp.

I would recommend getting at least a 2 channel amp or a pair of monoblocks for the M80's as bdpf suggested. If you have the VP180 I would also suggest that be used with an external amp.

The extra 10-20 watts wouldn't make any difference. You need an external amp at these kind of levels.

reference is when the dial would be around 0, sounds like your playing it beyond that limit into clipping.
