Why stop with the receptacles? Why not run $1000/ft power cable from the outlet all the way back to the breaker box? Then pay the power company to continue the run back to the distribution grid, and ultimately a dedicated line all the way back to the power generating station.

How important is it to replace your generic receptacles with audio grade receptacles . I already replaced my stock power cords to high end Shunyatas. Would it still be necessary to still change my generic receptacles to audio grade?
