Several factors will enter in to it. Where you live and how dependable is the power. What equipment is hooked up to it. I had a Monster surge protector several years ago and it really made the music sound bad. I have no experience with their newer products. I would check out PSaudio stuff, They have a 30 day full refund if not happy. With a wide price range and friendly staff to work with and very helpful.
