With the plethora of wires that a system can create (especially if you are biamping with the extra amps and active crossover) I hated that setup.
I had ONE single outlet upstairs and in this ONE outlet I had around 12 items plugged in. I detested it dearly.
When I started putting my basement together, I made the electronics closet and inside that closet (and whole room) I have four 20 amp circuits.
Inside the closet alone I have about 12 double boxes (4 outlets each) so that gives me 48 individual plugs. Half are switched (I have 4 20 amp switches at entry door) and half are hot. They are spread over the 4 circuits so I can spread the load if necessary.
Each switch at the door covers one circuit. Each circuit (as it travels to the room) goes to a speaker location. So switch 1 controls the front left outlets, switch 2 controls center outlets, switch 3 controls front right outlets. switch 4 covers outlets in closet.
So now I have the wiring to put ALL my electronics into the closet and let switch 4 control all the switched items or, I can put my amps at the speakers and let the other switches control those, taking the load off 4.
Here's an early picture of the closet before I got all the wires pulled.
My wife understandably thinks it looks like a nightmare however, when I asked her if she instead, wanted the wires VISIBLE across the room.....you might know what she said.
btw, I've also got multiple runs of Mogami Neglex, multiple runs of Cat 5 and others so I will (hopefully) have all choices available to me as the room evolves.
Probably should say that.... the nest of wires that I had upstairs is probably what made me go nuts like this. I swore that if I could avoid ANY cords & outlet multipliers, I'd do it at almost any cost.
