Question about electrical outlets

I have a pretty basic headphone based system - headphone amp, digital and analog sources. There are six components total which need to be plugged in. Currently I have all 6 plugged into a Wiremold power strip which is plugged directly into a outlet.

If I were to separate my components, say digital into one power strip and analog into another strip and then plug both strips into the SAME outlet would there be any electrical "isolation" achieved by separating the components this way? I don't currently have a second decent power strip to try so I wanted to get some feedback before buying another one.

Thanks in advance for any insight!
