Hey!
Man! Danny really opened a big can of cables here. Anyway, I can't believe that it is now 2021 and audiophiles still arguing about cables!
For me personally, I don't have an uber fancy expensive system compare to many people here, but I can hear differences with each cables, connectors and etc swaps. Back when the NY group was active years ago, I had members over and sometime they would bring over stuffs like DAC, amps and of course cables and we all could hear differences between each cables.
So, my take is... if like and think your system sound great now and you spend money on "audiophile" cables, put them in your system and you can't hear any differences compare to the free cables that came with the components then consider yourself lucky. You just saved yourself a lot of time and money!
Anyway, beside that I do enjoy watching Danny's videos on speaker designs... the "Acoustic Center" really confirmed what I've been hearing over the years. Well, I'll catch up with the new episode.

PS
By the way, a little complaint... your flat earth model is a cube earth. I thought flat earth people believe is more like a disc floating in space.... just pulling your cable here
