I've found the most efficient way to modify the sound is to change cables instead of hunting for a different player. It can help some with poor CD's if they are harsh, etc.
In many ways cables has evolved along with the players. In my collection of junk, I have an old late 1980s CD player that sounds terrible using a modern pair of interconnect cables. It actually sounds pretty good if I use a pair of old Audioquest cables that date from the same period.
My conclusion is those old cables where made for the equipment of the time. Those old cables veil the highest highs of modern players. On the old player is softens the hardness of the highest highs that was common at that time.
