ok - so a quick history... I have a Denon AVR-1803 hooked up to JBL S38II's as mains, an S-CenterII and a Sony SA-WM40 subwoofer. A couple of nights ago the power went out at my house for about 6 hours... of course, I had to reset all the clocks in the house, etc... my reciever was also in need of some tuning (which I thought was strange). So i put things "back" to where I thought things were what I had thought they were set before, but now the system sounds MUCH MUCH better than before!? Hard to explain, but the simplest way is that previously my "LARGE" setting didn't sound "LARGE"... I was kindof dissapointed before, but now it sounds GREAT! has this happened to anyone in the past?
