Dedicated 20 amp circuit - Electrician laughed!

Great information, thanks for all the input...  

Ok so let me ask this then::::

Would a power regenerator like those from PS Audio not negate this need?  If I get a power regenerator, it's totally regenerating clean power so is there still a benefit to having a dedicated circuit?

There’s so much real expertise here, I’ll only add one thing about my own situation — If I find a way to test my outlet and see that it is noisy, I plan to make it dedicated (if price is reasonable). Why? Couple reasons.

One, as MillerC. said (at some point, maybe not here), one can learn to listen with more attention and acuity; a better line creates good conditions in which one can hear more. If one doesn’t do that — because they can’t hear a difference *now* -- then one has blocked that path of growth.

Second, I’ve gone to some trouble already to deal with power — a conditioner, good speaker wire, power cables for my gear, etc. I’ve not gone crazy but I’ve not stuck with stock cords. That approach — not to accept any lowest-common-denominator elements in my system — seems logical to extend to the breaker box IF (and this is a real, genuine "if") there is evidence that there is noise or other reasons to doubt the line. If there’s not, I’m happy to let that go.

Here you go @dtximages try this.

What does your system consist of? For example mine in the living room consists of an integrated amp and a raspberry pi4 roon endpoint. My server is in a different part of the house on a different circuit. I imagine an electrician would laugh at me as well for wanting a 20 amp dedicated circuit. If I was running 1.5kw monoblocks, streamer, CDP, TT, preamp, DAC yeah maybe it would be a good idea.

No.

Yes.

Now listen close, because this stuff does not work the way you’re being told. Its hard to understand mostly because almost everyone is getting it wrong- and almost everyone is getting it wrong mostly because instead of doing and finding out they accept the same old same old as everyone else. So please read my system description and consider every word very carefully. https://systems.audiogon.com/systems/8367 Unfortunately you cannot hear it, not without coming to Seattle, but you can look and see pretty much every single little thing in that system from the panel to the speaker cones has been tweaked or modified in one way or another. What you can’t see are all the countless things that were tried and discarded.

Everyone wants to think one and done. "I got a conditioner." One and done. Does not work like that.

When it says in my system description that everything matters, and no one thing is any more or less important than any other, I mean every single thing. Otherwise I would have said amplifier, speaker, etc. Everything means everything. Every single inch of every single wire, all of it.

You can get your conditioner, great. If its a good one it will by definition be an improvement. But no matter how good it is, and I do mean no matter how good it is, you will still be able to improve the sound by improving the first foot of wire coming out of the panel. And the last foot of wire going into the panel. And every foot in between. And the last foot of internal speaker wire. Every stinking inch of it matters.

Not like you’ve been told? Sorry. Truth. Only way I roll.

I use a PS Audio P20 for powering my whole system, and my system definitely sounds better with a massive Elrod Statement feeding the P20 from the wall instead of their supplied basic power cord or even a VH Audio Airsine.  Now, I have only run it off my dedicated 20 amp circuit (wired with 10 gage for overkill!), so I cannot specifically speak to the dedicated vs. non-dedicated circuit question.  But the fact that the power cord can improve things certainly tells me that even the upstream configuration makes a difference with a regenerator.
I have switched from standard house circuits to dedicated lines twice in my life, and both times I was well pleased by the sound improvements rendered (more powerful dynamic performance, better micro-dynamic contrasts, fleshier palpability in the imaging, among other improvements).

I am with Millercarbon on this - - everything matters.
