This does not negate what I said.
If you use a 30A receptacle, it must be used on a thirty amp branch.
If you use a 20A receptacle, it must be used on a twenty amp branch.
You can use a smaller rated receptacle, i.e., 15A, on a 20A branch. The breaker is rated to protect the house wire, NOT what is plugged into the receptacle. 20A plugs can accept a 15A plug, which may be attached to a load with 16# wire or less.
If there is a requirement that only a 30A receptacle is allowed with a 30A breaker, which would require a minimum 10# wire, then I stand corrected.
However, getting back to the original poster, 10# wire, which is rated for 30A, can be used with a 20A breaker. You don't HAVE to use a 30A, and it is also not needed for a *normal* home hifi load. The purpose of going 10# is not for more current capacity, but to lower voltage variations under varying load.
