Thanks for the link. All in all that was a pretty disappointing teardown. Just a couple of hastily snapped photos with no real detailed description of the internals. Maybe I’ve just been spoiled by iFixIt but that was a pretty lame article.
Also, BB favorite Techmoan has already debunked the “cassette tapes never sounded that great” statement:
tl;dw is that cassettes were perfectly capable of sounding nearly as good as CDs but by the time the hardware got to this level, the format was already moribund.
