AC polarisation. Does it matter?

As most of my wires(Electraglides) are reversed except for the wires to the cdp and tuner should I reverse the polarity at the wall plug? That would reverse to proper polarisatiom the Hydra but then the amp and preamp would be reversed. The way I have it now the
plug from the wall is Reversed .The Electraglides in my system are all reversed in that the positive and neutral prongs switch at the iec. So I have a reversed cable to my Hydra with reversed cables from Hydra to amp and preamp which I imagine wouild be proper polarised as the hydra is switched and then it is switched back from the reversed cords from the hydra. The cords from the Hydra to my CDP and ny tuner are correctly wired so they would be reversed. What would be best for me to do. I could reverse the wall plug and the CDP and tuner would be correct but the amp and preamp would be reversed and vise versa.

With the reversed cord going to my hydra and reversed cords from my hydra to the amp and preamp does it not balance out assumnming the house is wired properly? As for the CDP and tuner they would be reversed because their cords are properly wired .Which would be worse, reversed sources or reversed amps?
