Power conditioner vs use of a audio grade outlet?


If I have a $7000 Power conditioner and really nice power cables is there a need for audio grade outlet? Maybe it's a dumb question but if I didn't have this other good stuff maybe I should get an audio grade outlet.

Pangea seems to offer a good outlet for about 100 bucks.

The ground conductors must be bonded to neutral at the service entrance. Otherwise you risk having neutral at one voltage and ground at another with high impedance between. In the event of a short to chassis the return current to neutral (perhaps up a pole or on a transformer pad) will be through the top soil which is high impedance, preventing it from working to trip breakers and fuses, leaving a potentially lethal voltage at the chassis.

By bonding ground and neutral at the service entrance you ensure a low impedance return to ground and if a short occurs increase the chance of tripping the breaker before melting a wire and starting a fire.

50 years ago netural was used as a way to ground chassis (the outer metal envelope of appliances) and experience taught us this was bad because neutral carries current, and when that current flows through a bad connection it raises the voltage on the neutral.

The ground wires may go bad, but they should not be carrying current except on an unexpected short, therefore the ground conductors remain at near 0 volts at all times except when a short occurs.

The formula V = I(current) * R(esistance) will help here. If I is 0, then V must be 0 even if R is high. That’s the normal state for the ground wire across your entire home.

Neutral often has current anytime you turn a switch on. Say 10A. Now 10A * R means V is not zero. If you tie that to the outside of your amplifier, you now have an AC voltage you can touch!

This is why 2-wire electrical construction is prohibited today.

@erik_squires  , on the same subject, what is it that happens to the voltage carried by the white neutral wire when it reaches the neutral/ground bar in the electrical panel that makes it no longer dangerous?

Thank you for sticking with me on this, @erik_squires  , if you could bear with me just a bit longer:

if this was the ideal circuit in a utopian world of circuitry and there was NO resistance

(V=5A x 0R=0V)

then you are saying that although 5 amps of current are flowing through this white neutral wire, it is not dangerous because the formula dictates that 0 volts are created.  In this hypothetical circuit.  Correct?

But you are also saying that in reality this hypothetical circuit doesn't exist, and the example you used of what does exist is

v=5Ax10R=50V

so the white wire (with 10R) is not only carrying current, but because of the 10R it is also carrying volts?  Is that correct?

(And on an aside, doesn't this mean that the old saying, "it's not the volts but the amps that kills you" is not exactly correct, as I am getting out of this that amps without R would not be dangerous?)

But back to my question that prompted this explanation from you: in the real world circuit that you used for an example

V=5Ax10R=50V

what happens to that formula when it reaches the neutral bar via the white wire?  Is it that because of the massive ground cable that ALL resistance disappears at this point and the ingredients for the 50V are gone?
