If its solid state or digital leave it on.Power conditioners is a difficult subject.Most help in some ways but also create other problesm.one unit hich i have treid and really works is the PS 300.The PS 600 is also a very good unit.I would run dedicated ac lines before i did anything if it is feasible.That is generally the best bang for your buck.One line for every component.dont put two components on the same line if you can avoid it.
