My electric company put a whole house surge protector behind the electric meter. It's something only the utility can do, but is the best way to prevent surge. It comes with a multi-thousand dollar insurance policy. Costs $10/mo. on my bill. On plugging the amp directly into the wall vs. into the power conditioner, my NAD M3 integrated stated in the manual it should be plugged directly into the wall. I did research this and there is a difference in plugging into the wall vs. into the power conditioner depending on whether one is using separates or an integrated and depending on the component manufacturer's instructions.
Power Conditioners
Not sure if I placed it in the correct topic but here goes. I was just wondering how power conditioners work, as I want to buy one. There are conditioners with only filtered inputs and conditioners with some filtered inputs and some unfiltered. I believe the unfiltered ones are for analogue devices. But why should these go into the unfiltered part? If I buy a power conditioner for example with only filtered inputs, will I not be able to put my class A amp in? Or will it have a negative effect?
