I worked in a store once and fried $5000 pre-amp and a $600 sub in the same week by just touching them. I have witnesses too. I was simply near them. I've owned maybe a dozen Denon recievers and dvd players,- all of them have gone nuts or died or simply half of it doesn't work. At least you have some fun in the killing of your speakers. At least you know why and have a good reason. A good party could do any of us in!
