Install A Dedicated AC Line at home

You want two, one for your main components and a separate for your amp.

Overkill if you understand electricity. Just be sure to wire the two circuits on the same AC buss. And choose the one without refrigeration, etc. 

2 grounds ,one common ground ,the other a insulated isolated ground on a separate Copper buzz Bar, amd a 2 inch  4 ft long ground

Bad choices. Adding additional ground rods can reduce the efficiency of the Earth which is there primarily for lightning strikes on the power lines. Unless it was engineered, you probably made things worse.

These were done a Madter Electrician Audiophile,we changed the original ground rod for they had used brass and it rotted the 2 Solid copper pipe I had Heavy silver plated to not rot , same ground as original but much better 

my system sounds night and day better , that’s the only thing that counts.

and I have at the breaker box a $300 Siemens surge protector which pikes up even little spikes . I had a dedicated 15 amp breaker before , even with a $5000 innuos streamer , in this new Dedicated 30 amp breaker4 wire sounds better then with the streamer vs my little green computer , it’s That good !

Great article, thanks for posting it! I might have to swap out the aluminum flex conduit for steel EMT, forgot about magnetic shielding, aluminum only does electrical sheilding:(

I will have to read the section on isolation transformers a couple of more times but it looks like I will want to do something along that line as well.

The rest of my work looks good, nice I had not finished the install, easy to change to EMT/

Thanks!

Adding additional ground rods can reduce the efficiency of the Earth which is there primarily for lightning strikes on the power lines.

Not when tied together, and spaced (a good rule of thumb is the length of the rods) equally apart from each other. I admit (most don’t know this), ground rods *are mainly there* for (discharging) lightning strikes. Having been a Radio Broadcast Engineer for over 3 decades, I’ve always dealt with lightning, lightning strikes and lightning damage (oh what fun; but really, what an experience!), with those big lightning rods (towers) sticking straight up into the sky.

I think what confuses many is when they start beefing up their ground rods, they’re most times simultaneously also beefing up (without realizing it) their audio system grounding and bonding infrastructure; hence the perceived and achieved lower noise floors.

Overkill if you understand electricity.

You do realize this hobby is about excess, headroom and overkill, right? 😉

@raam Just to clarify, AC-HCF is considered better than EMT (see the chart on Middle Atlantic's page 13). AC-HCF is considered a 1/2" (depending on gauge of wire) steel-clad MC.
