Time for dedicated outlets!


I would like some advice on what exactly to tell my electrician to be sure I get what I need. Is just saying that I want two separate dedicated lines to the listening room sufficient or are there other key fraises that should be included in my description of the work I would like done?

That's a violation of the NEC

I'm assuming NEC is an American standard @cleeds ?
bumperdo, you need to read cleeds post above. A separate ground on the sub-panel is contrary to the NEC.
Yes, it is either
12-2 Romex or 10-2 Romex...."cleeds" is on it!
You can debate which one to run for a 20 amp duplex outlet but what you have is a Black Positive conductor, a White Neutral conductor, and a Green Ground conductor. 
In the Service Panel: the 20 amp breaker will have only the Black wire,
   The White will be attached to the Neutral Bar and the Ground to the 
   Ground Bar.
