Perhaps none of us who wax eloquent about cassette (or even vinyl) sound today had a second thought on moving over to CD back then.
Each one of us had some convincing reason to do so, most of which are listed in this thread. Most of us junked our cassette decks, Walkmans, turntables, and respective media while some with collector/hoarder (both are different) mindsets had boxed and kept them aside, but never used for years together. There’d be an exceptional one who continued listening to them in the intervening period. It’s only when the vinyl revival started few years ago, did some get back to dusting/refurbishing and trying out the older equipment and media and discovered an again-found love. Did any of those reasons to move to CD become inapplicable now? I don’t think so. We just found newer reasons to go back.
Just goes to say how human mind as well as the collective mind is fluid and nothing can be taken for granted for ever.
