Some valid and some not so valid points on this subject.
The amperage of a circuit breaker has several requirements. Example: a 15 amp breaker should have the correct wire distribution...not to exceed the capability of the breaker....this should be 14 gauge 2 conductor + ground. A 20 amp circuit should be a 20 amp breaker with 12 gauge 2 conductor + ground. Exceeding the recommended wire gauge for a specific amperage breaker is just plain dangerous.
Attempting to wire 3 separate circuits to your hi-fi room to 3 separate outlets is a terrible waste of $$ and you will absolutely assure yourself of a serious ground loop & concomitant noise/hum.
Go ahead and bring in 1 dedicated 20 amp circuit to a good quality duplex (2 plugs like most household outlets) outlet.
Many people are under the misconception that the electrical ground for your home/apartment/domicile (in the foregoing referred to as home) is provided by your electric company. Very false. The ground is a true earth ground made by the electrician that wired your home. It is a 6' copper rod driven in the ground and connected to your electrical panel with a large single conductor to the ground bar in your service panel.
All of your grounds go to that ground bar in your service panel.
The only wires that your electric company brings into your service panel are the supply or positive wires (2) and a single common conductor.
The 2 separate supply wires are 120 V and supply the 2 supply bars of your service panel and the single common conductor go to the 2 common bars of your service panel.
The breaker fits over the supply bar and common bar to make a circuit breaker perform.
The best arrangement is to purchase a hi-quality (example: Furman) 15 amp power strip. You can spend additional $$ for a power conditioner or the like but I would recommend just using the power strip first.
