Sir, arguing about what someone else can, or cannot hear is like arguing about politics or religion. It's futile. If you can't hear the difference then good for you. But science can demonstrate there is a difference between Lossy & Lossless Codecs even if you personally can't hear it. Same goes for fuses, power cords, tube connectors, interconnect cables, speaker cables, and the like. In those cases there's a lot of snake oil being spread around and science supports that conclusion. (I haven't seen any research on a Bag of Magic Rocks so I won't comment on them.) I won't argue the point as it's like trying to show a blind man the difference between red and blue. He just can't see it.
