Install A Dedicated AC Line at home

Thanks everyone for your helpful comments — I’ll study them carefully before proceeding. 
 

In reading over the comments, it became apparent to me that I had a typo in my original post. My intent was for the electrician to install a total of 4 dedicated 20 AMP circuits with 10 gauge wiring — one for each of the JC1 amps (2 total), 1 for the AV equipment at the front of the room, and 1 for the HiFi source equipment at the back of the room. I think that addresses the very valid concerns from the first response post. 
 

Thanks again for everyone’s suggestions. 

Carlsbad, you have a physics degree, what does that have to do with knowing how to install a dedicated line and being an electrician? nothing LOL I used to be an electrician I'm retired now you don't have to design a circuit to put in a dedicated line, that's hilarious, all you have to do is run a line from a separate circuit breaker  to your outlet and now you've got a dedicated line, it's not rocket science please don't make me laugh more.

and to add to that a separate circuit breaker that has no other lines running to anything else.

See, I told you @jea48, knew his stuff.
