How to protect system from Electrical imbalance


In an all Solid State system, the common practive is to keep all of your electronics on at all times. I guess except for long holidays or vacations.

My questions is that what do you do to protect your system from electrical imbalances. I have found that so many of the power protectors degrade the sound. What do you do to protect your expensive system while not degrading the sound of your system?

Thanks.

I use TORUS POWER ISOLATION COMPONENTS.
As my outlets can only give me 15a or 20a,
the Torus can easily give,50a-400a,and total isolation from the outside power grid.I run 7Bssts and and if run into 4ohms
they would like 16.5a at full power.Blows my HYdras out of the water.Excellent to hear a MAJOR CHANGE FOR THE BETTER.
