Ok i'm new into this.
i got a new system (power amp Rotel 1095 , receiver , CD player , PS3 ,TV).
what kind of surge protection i need ?
Depends on what the power is like where you live. If you live in an urban area, you probably need no added surge protection. If you live in a suburban or rural area, you may need surge protection to guard against near hits by lightning. Then you need a a whole-house surge protector that is usually installed by an electrician.
