Power Conditioner? Furman?

Hi,

I need something to protect all the components I have, I am relatively new to the audiophile world. I currently have connections running via a belkin surge protector but I do not know if this is adequate enough protection.

I run an NAD amp, pre-amp processor, DVD and media box, and TV through this right now.

I seen a Furman PL-8, I am wondering would this be adequate for my needs?

Any help appreciated.
