Opinions are like...

My opinion is most power cables are just plain ripoffs. Use a decent cable and forget it.

Power filters can be very valid. But they have to be good ones..I like Corcom.

If you have REALLY bad power, a GOOD (not cheap) computer type backup with PURE SINE wave out is useful, but costs. A lot.

I have found most places if I run a separate line for my system and use a Tripplite filter/spike protector I am fine. Fancy stuff ain't necessary.

Hint: If you use a filter put it close to the system and keep the cords from it to the system short.
