Surge protectors and power conditioners - Good idea or bad?

Years ago, I bought added surge protectors and a power conditioner to my system, including surge protectors/ power filters to my Martin Logans.

Recently I revisited this idea and discovered that many people say to avoid the above, given it's rare to get hit by lighting and blow out your components and that both surge protectors and power conditioners can negatively impact overall sound.

Thoughts?
