Am I Splitting Hairs With My Connections?

So I have a Monster Power Center and I’ve always wondered if it really makes a difference whether I plug my CD player’s power cable to the outlet marked "CD"? And the same with any other component. Are those outlets somehow tailored to the component that is labeled? For example if I were to plug my CD player into the TAPE outlet, will a difference be made? Will I hear it? Or are the outlets on the back of the Monster all the same, and the labels simply for convenience?

And, second question, what is the answer for the same example on my receiver? Like if I plug my CD player into the TAPE connection will there be a difference heard?

I know this is perhaps trivial, but it has been bugging me for a long time, any responses will be appreciated.

Thank you! Happy Listening...
