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.

heaudio123"If you are seeing 40W of losses on a 140W output amplifier, you are either using a power cord way too small for the application and unsafe, you have some serious non-normal contact resistance that is again generating unsafe losses that could cause enough heating to melt the plastic holding the contacts, or there was measurement error or a combination there-of. "


There are actually multiple other explanations, possibilities, and causes of this problem, issue, and anomoly but you’re black and white, absolute, narrow way of examining, investigating, and exploring the issue blocks you’re conscious mind from considering the alternatives and this is a common, frequent, repeated problem in your perspectives and why the conclusions you reach, develop, and promote often lead to erroneous positions that you then seek to defend against all who dare question or challenge you. Open you’re mind up perhaps would be my suggestion.
