Not quite sure what you really mean here?
I mean if you have good sound from all of your components then you must have them connected correctly, in a sense.
It is possible you could have some out of phase ( left going to right and vice versa) but that should be obvious to the ear?
I admit I have a lot of components connected and no matter how neatly I try to run all the cables it still ends up looking rather like a rats nest.
What you really want to try and avoid is running interconnects directly over power cords, again easier said than done at times, this could be especially crucial with analog sources like a turntable.
Just look it over and take your time doing one source at a time verifying phase to phase and location and security of the connection.
Or do you mean, should you be using xlr instead of rca or digital instead of analog interconnects if your sources have these options?
Enjoy
