Install A Dedicated AC Line at home

OP,  you might reach out to the local audio club and ask them who has done work for them. They'll cut down the time you'll take random looking for an electrician who knows audio well.

I grew up in a construction family.  It boggles my mind how many people think it is as simple as hiring a guy with a license.  

There are many people here on this site that are well educated and have zero understanding of electricity.  

A high school education isn't required to be an electrician.  Formal training for an electrician is very limited.  Electricians generally learn as an apprentice and it mostly involves figuring out where to put what colored wire.  No understanding of the physics behind it.

So if you think anybody with a union card understands the nuances of providing power to a high end electrical system I wish you luck.

you need to get someone who understands what you are trying to achieve to design the circuit and then hand the plan to the electrician. Then provide oversight to make sure he does what is on the drawing.

Great tip Jerry.

I hired my regular local licensed electrician. I showed him the JPS outlets and cable and he smirked but did the work anyway. At the end, he told me that the JPS cable was the easiest cable he has ever worked with and asked me what it cost. When I told him, he walked away laughing.

No problems with those lines now going on 25 years.

Most sparky's will just want to argue with you and tell you why you don't need to do this and if you insist they'll say your crazy and anyone that says you need to this is just plain nuts! I would Study enough electrical handbooks and diy. It isn't rocket science and can be most enjoyable. You'll want to run two or more home runs to your room.
