really? .89c ground lifters?

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.

The only way to get a shock from the B+ is to actually put yourself in series between the B+ and B- ..... Lifting the safety ground would not change the likelihood one way or the other.....

Yes, it does not matter tube or transistor. The real issue would be if somehow there is leakage from a power transformer.
