http://www.thestreet.com/...-playstation-1-rocks.htmlI've tested a SCPH-1001 and a later SCPH-9001 and can honestly say they both sound really, really terrific. My new 1001 is currently having problems (more about that in a minute) so a direct comparison is not possible at the moment.
But I can say that both models sound better than they probably have any right to sound -- terrific midrange, good bass and slightly rolled-off highs. Don't just take my word for it. My friend, audiophile Art Dudley, writes in the latest Stereophile that he and his wife preferred the sound from his test PS1 to his expensive Sony component CD player. Stereophile's editor, John Atkinson, added that the PS1 didn't test very well but sounded pretty good when he heard it playing as part of an affordable hi-fi system.
Sounds like it could be true. There are many other articles out there on the net about this subject.
