Hi: Is it worth adding a power line conditioner to a stereo system?What are the benefits if any? I am looking at a Furman Elite PFI 15 as need 10 outlets for my system.Reading conflicting reviews saying they do nothing or make a huge difference in both sound & Picture quality?Thanks for any comments!! cool
