Re: CD audio are a scam + CD player failings
When CDs first came out, the reject rate was high.
Early pressings had to be scanned (listened to) at the pressing factory for drop-outs which put a price premium on them.
BTW, early CD players had two DACs, one for each channel.
The stereo audio stream had zero time lag between channels.
I was then playing various vinyls which has pseudo 4 channel effect when listened through headphones or alternatively on my Sansui Quadrophonic 6001 receiver through an effect switch which created 4 channels from the out-of-phase stereo information. Try listening to Queen, 'the prophets song' or Pink Floyd Ummagumma (sp?) on vinyl with headphones and hear the rear sounds. Modern CD players destroy that information due to the time delay due to only having a single DAC handling the stereo channels.
