Ahem.....gents....to get back to the main subject matter, YES be careful employing both loudness and bass boost. My 9090db I just recently parted with would part your hair at 9 o'clock. Never went past 10 oclock, as it just hurt. I used loudness, but no other boost. And yes, submit the s/n if possible, and have that thing benched and checked. Good luck. Some of the behavior here is embarrassing to both Americans AND AK'ers. Let's all chill out.
