Apparently the very earliest of PS1 consoles (circa 1994-5 SCPH1000 and SCPH1001 models) are now highly sought after because the audio chips create a vinyl like soundstage with no jitter.
People on audiophile forums are comparing $10 used PS1's with CD decks costing up to $1000's and its a tight argument right to which sounds better.
If this is true, which 100's of people on the net are finding is true.. It might be worth hooking up that old dusty playstation to your receiver.. You might become a believer.
So far, the findings are that the PS1 console delivers better bass, wider soundstage and maintains excellent detail. However, it was found that db level was a bit lower than most dedicated CD players.
Be warned if your wanting one of these PS1's for this purpose, alot have bad CDrom drives.
I have a SCPH1000 from 1994, I don't have a receiver and speakers though
