Surge protector or power conditioner?

I know I’m opening up a can of worms here but I’m going to ask anyway. I have been looking at a surge protector/power conditioner, specifically the Furman elite 15pfi or 15dmi. I don’t feel as though I need a “power conditioner” because I don’t notice any emi in my system. I mainly want surge protection. I have read that people have experienced negative results when plugging in their power amp into a power conditioner. Idk how true this is because I have never had a power conditioner before. 
My question is, is there any company that makes a quality surge protector similar to the furman elite series (13+ outlets) without the “power conditioning”? Also, is what I have read about people’s amplifiers being restricted due to power conditioners accurate?
