Should I skip my power conditioner?

I have a Monster Powerbar 1100 power conditioner/surge protector. The main reason I bought it is to protect my equipment from any lightning strikes/electrical spikes and for convenience for all of my plugs (I have it mounted to the underside of my stand). I'm no Monster fan or hater but for about $125 shipped, it seemed like a lot of useful features plus surge protection. I've been doing some reading that it may actually be better soundwise to not use one though, especially with the amp (Arcam AVR300 in my case). I'm looking for any opinions on the subject of if I should continue to use it, or use it for everything but the receiver. If I don't use it, will just a good surge protector yield any negative results? The details of my system is in my system link.

Thanks for any input,

Scott
