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 bought all used equipment, but still a lot of money to me. I do not have a surge protector, I'll have to look into that in the near future. It does have 4 feeder wires, 2 hots a neutral and equipment ground. The neutral buss is isolated from the panel and the equipment ground buss is bonded to the panel.

First off you are the customer and he should not laugh at your request. That is rude and unprofessional. The main reason to have a separate 20A is so the system does not share the feeds to other devices. I was able to get the lights on the circuit to blink in time to the bass notes when I was replacing some wiring and had to move the system to a shared circuit. Would he laugh at having an AC unit on a separate circuit..no. Same thing. it is to insure the supply to the devices. Find another electrician.
