Digital isn't perfect but compared to what an analogue playback system does, it might as well be considered as such. It gave them nothing to write about when a $120 disc player could reproduce audio as well as a $2000 player. They seemed to have doubled and tripled down on the nonsense ever since.
Not sure why audiophiles fall for it, other than the general "tweakiness" aspect of some audio enthusiasts who are always looking for the next thing to spend their money on. It's tough to have a hobby when if you buy the gear, you have little to complain about until it's made obsolete.
I'm on the opposite side of finding it interesting though. There is a lot of "your ears aren't good enough" dog piling going on to shout down any doubts about cables and whatnot.
