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.

Is there a difference using 30 amp breakers instead of 20 or just overkill
Does it matter either way
Yes, there’s a difference. Check NEC and your local code. NEC says you can’t use a 30A breaker on a 20A receptacle.

What duplex outlets did you install? Many duplexes are limited to 10 awg wire (8 awg is too large).
That's very true. I use 8 AWG on some of my dedicated outlets and used a pigtail to connect to the receptacle.

"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.
