Opinions please re this

If a hifi ( CD ) player was made and first sold from 2003 and at the time was High end / cutting edge , Would that component still be HE / CE ? , or over time with technology moving on at a great rate and the evolution of chips would it now still be HE /CE , Also would older internal components still deteriorate as std models do
Caps need replacing ? along with resistsors / transistor's , dry joints on soldering etc ?
Even high end components change over time , don't they ???
