Early in your journey, when you are stretching just to get into what may be barely considered “HiFi”, speaking from my own experience at least, your mindset is just on obtaining the gear you can barely afford. The last thing you want to hear is that you should allocate a portion of your budget for cabling, including power cords.. It’s far more convenient to believe it’s ridiculous that power cords have an effect, and it IS a ridiculous concept.
I believe this is partly what has driven people to be so passionate about this debate for so many years, using the same common-sense based arguments that don’t apply, and passionately doubling down while refusing to find out for themselves by doing a simple blind test in their local HiFi shop. It’s far more convenient, budget wise, to believe that aftermarket cords make no difference. Very few people won’t hear an improvement with premium cords in a blind test when they actually get to doing it, and you absolutely don’t need to be an audiophile to hear the difference (my wife and daughter hear obvious differences but couldn’t care less).
