I have been looking at a surge protector/power conditioner, specifically the Furman elite 15pfi or 15dmi.
Very good value-for-money choice.
I don’t feel as though I need a “power conditioner” because I don’t notice any emi in my system.
You will only notice it once it is removed, and you A - B your system with EMI present vs. without EMI present. Trust me, you WILL notice. :-)
I mainly want surge protection. I have read that people have experienced negative results when plugging in their power amp into a power conditioner.
Agreed - given the cost of our components, it is wise to protect them. I have not personally noticed anything negative with my amps plugged into a power conditioners (only huge improvements), but many have claimed they have had issues so your concern is well founded.
If you are concerned, you should perhaps arrange with a dealer to get a conditioner for a trail period.
