really? .89c ground lifters?

the human body is an impedance. resistance, inductance and capacitance. You have an impedance. If there is a system fault or a lightning strike, or some such, very high voltages can pass through the equipment through you to ground. Since you lifted the ground, you become the easiest path to ground. We are not talking about audio equipment. We are taking about electricity, voltages, sometimes very high voltages, current and impedances. a blown transformer and you have very high voltage spikes, a shorted device or a failed tubed device and very high voltages hit you passing very high currents through your body. Since you are an impedance, small but there, you will draw very high currents.

Simply electronics/electricity rules.

enjoy.

That is a lot different statement than the one I quoted of yours in my previous post......
Yes if any part/s of the body is placed between a difference of potential, current will flow through the contact points. If the voltage and current is high enough there will be electrical burns at the entry and exit points. And yes it can kill you deader than dead! In the case of a ground fault the current is non discriminating.... It will take any conductive path available to get back to the source. It likes the least resistive path but it will still take any available path.

You really need to go back and read my other responses to this thread.....

I understand what you are saying. However, in terms of electrical design and safety and codes, you never, never, never lift grounds. If there is a problem, hum, ground loops, etc. isolate the faulty piece of equipment or cable and fix or replace it. Like I implied earlier, all you need is for it to happen once for you to realize what a bad mistake you made by lifting the ground and compromising the electrical safety. That is, if you are still alive to talk about it. It may not be you. It may be a child or guest. I have experienced ground loops and hum before. I took the time to isolate the faulty equipment and fix or replace it. I'm very much into great music and accurate, detailed reproduction of the signals, but not at the cost of safety. Life is short enough as it is. I don't mean to rain on anyone's parade but, cutting corners and shortcuts are not the proper way. One should never advocate compromising safety.

Enjoy

(I'm all grounded here. Or at least, electrically speaking I am.)

It's probably worth pointing out that the danger from lifting grounds is much higher with tube components. These typically have 300+ VDC - very deadly.

Also, this comment

"Having all of your high power equipment on one phase will overload the wiring, cause it to heat up (IxIxR) losses and cause the insulation to fail causing a major electrical fire"

seems a little out of touch in an audio context. It's unlikely that any audio circuit - no matter how powerful or loudly played - will draw as much current as a wall air conditioner. I don't know anyone who checks to make sure the air conditioner and refrigerator are on opposite phases. These two are a much bigger load than having your power amp and cd player on the same outlet.
