Single plug dedicated circuit?

I guess if you truly want to do a dedicated circuit wouldn't you have to be allowed to only plug-in one device. If you plug two items into the outlet isn't one item going to contaminate the other item with noise from the first item?

So a multi branch circuit would be sharing 4 items.
 

I guess it gets down to sharing and Best to share with one but tolerable and acceptable to share with 4 components plugged into the quad outlet?

So how many people are only using one component per circuit breaker which is the truly finest way to receive a pure signal, at least if you ignore what occurred before the current reached the circuit breaker.

I'm not sure what any of you think you gain by having an extra meter and panel.

I don't make any claims to being an electrician or having much of an understanding of electrical theory, but from what what I have read on other threads here on A'Gon on this subject, isn't some of the RF pollution happening at the neutral ground bar(s), and if so, wouldn't a whole separate meter and panel remove this factor?

Only if you believe there’s something that is injecting that in from your home AND that there’s somehow a magical RF filter that prevents it from getting back into your other panel. Where do you think that energy goes, and why does it not come right back in?

IMHO, you are better off using a surge protector like Furman wiht Lift/SMP or Zerosurge that have inherent filtering down below RF.


Now if you do believe there's some bad pool of RF energy in your neutral, then a great ground field is the way to minimize it.

I think what gets me with the Audiophile/power discussion is that it wants to go everywhere all at once with no single principle to adhere to.

The ideal AC circuit:

  • Does not waver in voltage
  • Is free of noise
  • Is a perfect 60 Hz signal

The problem is that the power coming in from the transformer and the demands of your home and the homes around you are noisy. OK, I get it. But the last thing you want is a wide-band perfect conductor. Ideally you want filters that remove as much noise as possible and some way to keep the voltage stable regardless of the load.

Well, you can’t have stable power because the incoming voltages are always fluctuating. A giant gauge wire will reduce the sag during musical playback but it can’t do a thing to change what he power company sends you.

@erik_squires  , as I have stated and will continue to repeat, my grasp of electrical and electronics is limited.  This is the thread that got me thinking along those lines.  (With my limited ability to understand, I cannot help but think that a separate service for the audio system would isolate it from everything else in the house.)

My opinion:

  • Make sure your ground is in good working order.
  • Run a sub panel from your main panel. This will give you big thick wires and minimal voltage drop due to load.
  • Use a voltage regulator in your audio room. This will minimize the effects of the outside voltages swinging due to power company fluctuations as well as other household loads like the oven, AC, etc. and it will add some amount of inherent noise blocking due to inductance of the autoformer.
  • Use RF/EMI blocking conditioners for all of your sources. Furman with LiFT/SMP or Zerosurge, all have excellent low frequency (relative) noise filtering.

I say this not just from listening, but from watching my home VAC swing no matter where I live.  By far the largest measurable improvements have come from the voltage regulator.
