I would suggest starting with a used Sony dvp s9000es dvd/sacd/cd player for about $600 or so.
It's an excellent unit for all three formats and the picture is quite good too. And when you shut down the display, turn off the digital processing, turn off the video processing, etc., the sonics improve quite a bit more.
It's built like a small tank and I believe you'd have to spend substantially more to get better sonics.
If, per chance, you don't like it, you can always sell again for basically what you paid for it.
-IMO
