You’re obviously a youngster, then! I’d been selling Hifi part-time for over a decade when CD was launched. The early players were die-cast magnesium and made to incredible engineering accuracy at the time. They were precision instruments containing a laser, hitherto a laboratory device. At around £550, they were very costly, more than high end video recorders, for example.I keep thinking about all the cheap, plastic components inside a CD player and I can't find anything really expensive you could use in a CD player.
Case, PSU, panel, remote control, transport, optics, servo, DAC, a few capacitors and resistors and there's the packaging, shipping and then some profit.
