If you already have dedicated circuits, you are 80 -90% 'there'. Next, check your AC power at the wall with a cheap volt/ohm meter. If it stays between 120 VAC and 123 VAC throughout the day/evening, you really don't need a regenerator, and you definitely don't want a dynamics-killing filter (power 'conditioner') in front of your amplifier.
If you MUST spend some money, get a balanced power unit for your front end stuff ;-)
And don't fall for the 'surge-protection' scare. All the stuff in your system (I checked ;-) have built-in surge protection for ordinary conditions. If you see thunderstorms headed your way, or you're going on vacation, UNPLUG EVERYTHING FROM THE WALL! That's the only protection you can trust ;-)
