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.

I wouldn’t listen to somebody that didn’t know what he was talking about. For 1, did he check to see how many amps you were drawing with everything running on that circuit? Of course not!
Was he concerned about eliminating any noise on the line from appliances? No!
Decades ago, I had an electrician friend put a device on my circuit that had my stereo (Smaller system than what I have now), computer and lights And I was pulling over 10 amps on a 15 amp circuit. Ever since, I have had multiple dedicated 20 amp circuits in my audio room. It’s pretty cheap to do when you are building a new house
