Take a look at the Monster product line
http://www.monstercables.com/power/
and the new H series of AVB power conditioners from APC, the leader in the computer space.

Both companies have offerings that properly sized, will absolutely make a very visible difference in your image quality.
Hopefully you will be using two different circuits both on the same phase leg. If you are going to plug both conditioners into one wall outlet - for reasons of budget or logistics - I would just get one bigger unit to plug everything into.
All things being equal, the sub should go with the rest of the audio to minimize the chance of a ground loop problem.
