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.

Yes a lot of electricians in my family. My, brother, Brother-in-law, their kids my son-in-law. 4 out of the 7 can hear, 3 can’t. The 3 that can’t, admit they can’t hear that well. All 7 learned a lesson, 10 years ago... One day at a BBQ they listened to what my system sounds like with and without the "snake oil". LOL

I had a freezer, that could mess up good sounding system, if it was on the same rail. All 7 heard, the motor noise via a listening session.
Swapped to the other rail, all 7 could hear the difference. Swapped to a dedicated 20, the 4 that could hear better, notices the difference in SQ.


The fact is you may not "hear" the difference but you’ll know there won’t be a problem either. The lack of a well thought out power supply in your components. Not, separating your system from all the motors, and crap in your home. Poor home wiring to begin with, make for a bad start.

OR

You can dedicate a circuit and not worry about any of that. Normally the folks that notice the biggest improvements in SQ, with a Power Cord swaps, are the ones that have no improvements in their VAC.
The "PLUG it, BURN it’ crew..

A dedicated circuit does not have to have a seperate ground rod to be dedicated. The ground rod addresses a different issue, but there is no code issue, where I'm at.  Only requirement  making it dedicated was, that no other consumers are on that circuit. It’s not a bad idea, I did it for 3, 20s and just went to arc fault (AFCI).
They're to sensitive. I can’t plug in hot or it will pop the breaker.

The hospital plug is so you don’t blow the joint up when O2 is in use. Unplug then, disconnect the ground strap. Reconnect the ground strap then plug in. Pure copper, tight, heavy conductors, and larger screws in the receiptical.
