I've lived in houses where I was able to have a dedicated circuit and ones where I didn't. I now live in my retirement house, a detached patio home, and to install a dedicated circuit would be very costly, entailing a new panel box and more it's weird wiring involved, anyway I have never really heard any huge improvement from having dedicated circuits. Of course I'm only going by memory but if any significant or game changing difference involved dedicated circuits that would be something memorable.
Dedicated 20 amp circuit - Electrician laughed!
I brought my electrician out to my house today to show him where I would like to install a dedicated 20a circuit for my system. He laughed and said that's the stupidest thing he's heard and laughs when people talk about it. It said, if you're going to do it, you have to have it separately grounded (shoving a new 8 foot rod into the ground) but even then, he sees no way there can be an audible improvement.
Now, he's not just an electrician though. He rebuilds tube amps on the side and tears apart amps and such all the time so he's quite well versed in audio electronics and how they operate.
He basically said anyone who thinks they hear a difference is fooling themselves.
Personally, I'm still not sure, I'm no engineer, my room's not perfect, and I can't spend hours on end critical listening... But, he does kinda pull me farther to the "snake oil" side and the "suggestive hearing" side (aka, you hear an improvement because you want to hear it).
I'm not taking a side here but I thought it was interesting how definitive he was that this not only WILL not make a difference but ALMOST CANNOT make a difference.

Here you go @dtximages try this. http://www.ppowerus.com/audio/products/pp1500/ 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. |
Theories are never proved. Ohms law holds in a ohmic device. Calling it a "law" was simply a convention it could have been called Ohms obersvation or Ohms theory. http://oer2go.org/mods/en-boundless/www.boundless.com/physics/definition/ohmic/index.html |
Aluminum wire is used mostly in large guages into the main panel or a subpanel. You need to use a grease on it as well. Aluminum was used for a time during the 1960's wiring entire houses, copper was scarce because of the Vietnam war. I used to own a house built in 1967 wired entirely with aluminum wire. |
