Dedicated Electrical

@offbrandracing, See article below:

run one big wire and split it up.

That would be a standard configuration for a sub-panel.

Muliple lines runs the risk of ground loops. Even if this is avoided every wire is an antenna bringing RFI into the system. So one single dedicated line is the way to go.

@millercarbon is that the reason that a couple of my components were manufactured with only two wire power cords (meaning no ground)? My Maranzt SA10 does not have the ground, nor does an old M&K subwoofer I am still using. Long ago a manufacturer (that I won’t name) suggest "floating the ground" with a 3-to-2-blade adapter to try to get rid of hum; I am not at all planning on doing that, but would that theoretically be a solution to RFI?

(And I should note that I presently do NOT have hum. And I am NOT "floating the grounds.")

Another question: is that what power conditioners theoretically do? Remove RFI?

Last question: in the room my system is now in, I put three dedicated lines in (my mindset was that I would not only be isolating them from everything else in the house, but from each other--at the time not understanding how the neutral bar in the electrical panel functions), so from what I am getting from this is that I should turn two of the three circuit breakers ’OFF’ and just use one of the three outlets?

Single "home run" Romex from breaker box to dedicated listening room.

No hum, no buzz, no drama.

I agree @millercarbon. Perhaps consider using MCC (metal case cable) if you have the opportunity to run a new (dedicated) circuit for your front end.

I always do but I’m an anal audiophile lol.

Though a bit more expensive…the metal casing (if properly grounded) will help reject/shield the wire from the RFI/EMI that looms around any space with electronic components and/or walls loaded with romex.

Think of it as the metal box most of your stereo gear is built in…once grounded it’s called a “shielded ground”

Perhaps called a “faraday shield” or  “faraday cage” lol 

Most audiophiles like to see the tubes on top of the case (exposed) and so do I,

but they can also pick up RFI/EMI. It’s why most vintage gear didn’t expose the tubes… not just because there were no transistors at the time (and the tubes where fragile).

Ill never forget after my first 300b SET build, only the tubes where exposed on top.

I was sitting there on the second night, proudly listening (pretty loud) when my cell phone rang through the loudspeakers! Lololololol

Admittedly it never happened since then though. All my other tube gear is shielded (no exposed tubes) except for the Supratek pre…
