@alaric62 "One uncle insists I should get Bose Cubes and an Acoustimess because "It sounds just as good". He’s never heard my stereo."
And another engineer might tell you to scrap it all and get good headphones with a good headphone amp instead. Whatever floats your boat, and trying is learning.
A good test comparing the PE vs the Kimber cables to get ideas and differences. As you try other vendors and designs, you may detect new differences yet again.
And those who cannot tell a difference, that’s okay, maybe they can stick with the PE cables or others for lower cost. Only the listener can determine if/why different cables "matter" more for them or not. Point is you have to try them to know them, as you did here. For those who try very little and rant on forever, just ignore them.
