Interesting question, in part due to the claim about how good the PS1 is. I own two of the recommended PS1s, picked up for $5 each from a consignment store. I find them to be terribly inaccurate CD players, with a bloated midrange, rolled off highs, and poorly defined lows. Very easy to pick out in a blind comparison, due to how much they alter the sound as compared to a high quality CD player or DAC. When I played my favorite demo cuts through a PS1 into a high end system, I was shocked by how much they were altered.
A good CD player, and several have been mentioned above, will be far more accurate and defined, capable of producing a beautifully deep, nuanced soundstage.
