My thinking is much like Sean. When I chose to do runs for my stereo system, I contracted 14 dedicated 20 amp circuits. This allows a dedicated run, with its own breaker, providing power to a single duplex. Often with only one male plugged into it. As Sean says this is a bit over the top, but Romex is cheap.
I sometime wonder if I should have used heavier gauge, my runs are 6, 10 and (minimum) 12 gauge, depending on the location.
The 6 gauge runs supply two 240 volt lines. These have option of 120 volt phase one and 120 volt phase two inside the same box. Consists of a Hubbell 240 Volt female twist lock plus two Hubbell 20 amp hospital grade.
The runs are all less than 30 feet, most are supplying a single device. When discussing "bang for the buck" this kind of overkill is a bargain. Between marginal and the ultimate, there is less money spent than the price for a single audiophile AC cord.
