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.
