As much as I try, I just don't get it........

A few YouTubers are always making changes to their systems, and having their audience listen ( I imagine you all know the few posters I am speaking about ). The show reviewers are posting some audio samples, and having their audience listen. I can go on and on. Honestly, however I try, I cannot determine what the big deal is, as these videos, with the " audio presentations ", are weak, poor, and tell me nothing. I listen to a lot of YT videos of my favorite artists, videos from some of my favorite recordings, some studio and some live, and many sound quite good.....but nothing from these others I speak about, do anything for me. This is why I admire Steve, at his Audiophiliac channel, Sean at his Zero Fidelity channel, and Paul McGowan at his Ask Paul ( from PS Audio ) channel ( and others ), who speak, and know, listening in this context, is useless. Am I alone in this finding ? Does anyone actually feel listening to some of these posters, with their " audio presentations ", get the impact, or " lack of ", of what they are hearing ? I am in no way demeaning these folks, but my audio and listening background, does not allow me to make good judgements in this way, unless I am in the actual room of the demo. Enjoy, be well and stay safe. Always, MrD.
