In my opinion, the place to begin is with one or better yet two dedicated circuits with 20 amp breakers and wire runs of 10 gauge although 12 gauge would work. In addition to that use high-quality AC outlets. Porter Ports sold here on Audiogon by Albert Porter is a good place to start that won't break the bank.
The use of dedicated circuits usually is a big improvement. If you can't have dedicated circuits at least upgrade the outlets if you have not done so yet.
