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.

"The Laws Of Electricity"!!!!!
Ohm’s Law is a guide. Nothing more. For what "Usually" will work, NEVER "ALWAY" will ANY of it work.
Ohm’s Law is a guide for whom ... electrons? It is in fact a valid, proven law, right?
To be fair, there are "non-Ohmic" conductors, but they don’t render the law invalid, afaik.

I know several people who not only put in dedicated lines, but also, put in a dedicated main panel for the audio system.  A local dealer did the same for his demonstration rooms.  Still, when a noise meter was plugged into the line, it showed that there was quite a bit noise on the line.  When a good power conditioner was then plugged into the line and the meter was inserted to read the output of the power conditioner, there was a dramatic lowering of the noise on the line.  This suggests that power conditioning does more, and it is a lot cheaper.

    It's this new thing.
We call it "Science".
Get used to it.
OR,
Get out of the way. Go back and hide behind that tree again.


...sounds like jollygreen is straddling both sides of the tree depending on which side best suits his attempts to justify his opinion.

Wow, Just ..."wow"!!

If you’re trying to win a technical argument there are generally two paths you can take. One is, “It’s a law of electricity or physics.” The other is, “There are no laws, only theories. So it’s only a theory of electricity or physics.” It all depends on which side of the argument you’re on.

I know a well known company that makes interconnects and they 100% do not believe in the breakin process of cables and that it makes a difference but the funniest thing is that when I ran several new interconnects through 300hrs of breakin, me and my son heard the biggest difference with the cables from the company that swears that there isn’t any difference.   My point is, it doesn’t matter if your Electrian doesn’t  believe in it, he can be dead wrong.  Do it if YOU BELIEVE in it.
