Power conditioner or outlet?

I have a Shunyata MPC-12a power conditioner. Read that it was a good choice for audio equipment so I bought it. I also have high end power cords to all my equipment, as well as to my Shunyata.

I have recently read comments from listeners that you should plug your amp/preamp straight into the wall. Is that the case if you have a good power conditioner? I will do so if it is a better option, just concerned about no surge protection for the amps...but also don't want degraded sound! I am asking this because I am a newbie at all this, more money than audio sense. I am interested if anyone might have any experience in this
