CD/DVD player advice

Hello to all. If this question is in the wrong location, I apologize. I am presently playing my CD's from an old Sony DVD player. I do want to upgrade this. So, do you find that a DVD such as an OPPO 105, sounds better for playing CD's verses a dedicated cd player of similar cost? I would say that an OPPO 105 that is in good condition,used for say $700 would be my top end. Would you recommend a dedicated cd player, which could also be used, or are the DVD players quite adequate. Right now it would not be connected to a TV. If I do later than the OPPO or something equivalent would be considered. Lets keep pricing down to $700 for either the cd or dvd player. Thankx to all in advance. If you need more info, let me know.
