Why does a Sony PlayStation sound good to me?

Okay I bought a couple of the Sony play stations with the rca audio outputs and hooked one up.First impression was not very good. Not detailed like my other CD players but left it on for a couple of days and am really enjoying the sound. It does sound more like an lp to me. I know the highs and lows are rolled off some and the build quality is poor but I like the sound. I now want a better quality more reliable CD player that sounds more like this. Especially for my CDs that are not recorded or transferred to digital as well. I'm happy to use this as an additional CD player but was thinking maybe Rega has a sound similar from some of the threads I have read. Sometimes I think welcome the soul of the music with too much precise details. Any suggestions on a different CD player?
