we learn that there are 1000 Americans killed by electric shocks every year. My goodnes that is a whopping 2% of those killed by smoking! Oh wait, that's based on deaths due to second hand smoke (estimate 40-60,000 per year), if we compare with smoking mortality proper, i.e. smokers, then that 1000 comes to 0.25% (of 400,000 a year).Perhaps you and your like can exert your energy where it could do more practical good? Just a thought.
LOL (and I told you not to make me do that!)

It's one thing to say, "Statistically, this is unlikely to affect me."It's an entirely different thing to actively increase your chances of becoming one of those statistics.
You are certainly free to rationalize your choices, and AFAIC you are free to harm, maim, or kill yourself as a result of your rationalizing. Just make sure there's no chance that your choice to deliberately ignore safety features and regulations will affect anyone else.
I promise not to invite anal-retentive safety types over for a listen, how's that?
bjh, your post relates only to a bared hot conductor coming into contact to chassis condition, and I agree that possibility is remote. On the other hand voltage leakage through a primary winding of a power transformer is possible and does happen on occasion.If you are talking about an audio system that is in an audio room with limited access sure then maybe no big deal. But if the audio system is in someones living room where possible access by small children or the like then safety should be a concern. Children like to touch things with both hands at the same time. Sure they have been told to stay away from dad's or grand paw's audio system but when someones not watching, kids will be kids. The deadliest current is between 100ma to 200ma. A leakage voltage as low as 50Vac could harm a child.
Face it, like I believe you were trying to say in your first post, the possibility of the owner user of the equipment receiving an electrical shock maybe remote. Sure if the floor is wood or carpet that eliminates a current path from a hand across the heart through say bare feet. And the chances of a user owner having one hand on a ground lifted component and the other hand on a grounded component is remote. I mean the old rule of thumb if it might be hot make sure your body is insulated from any grounded object and keep one arm behind your back.
What fraction of the general population comprises audiophiles? What fraction of the general population disables the grounds on their electrical appliances?
