Aaaugh Please recommend a DVD player

Feeling a bit overwhelmed.
Time to upgrade my year 2000 Panasonic DVD-RV31 and I know very little about DVD players. Now that I am looking, I feel even more lost with all the brands and models out now.
Why upgrade? The Panasonic is pretty weak when playing music. Hardly any bass and it has a very closed in sound.

This is what I am looking for…
Under 500.00 used
I would like for to include SACD
Not sure if this is standard still but I want both analog and digital connections.
75% music 25% Movies

Thanks in advance all you audiophile junkies
