Just aquired Denon 1905 for surround sound (movie). Lasted a couple of days and then suffered a serious burn out (lights, flames, power loss). All very exciting. Before I take it back to the store (and contemplate a Yamaha instead) has this happened to anyone else. Running micro 5.1 speakers with input from PC (optical digital SPDIF from soundcard). I was in the midst of switching from Surround to one of the movie options when it happened. May have been coincidence? Denon was not long on and had plenty of ventilation.
