This is a hot debate, like speaker break-in. Many will tell you that it is a snake oil gimmick, I don't totally buy that 100%. I have a Tripplite surge/isolated ac banks conditioner that everything is running through. It has a very high surge protection, and with the isolated banks seems to help. It also includes voltage and amperage readings so you can tell at a quick glance the status of your environment.

Works for me.
