CD player -> DAC

I have a moderate quality CD player and it's been serving me well for the past few years. Now, with all these great DACs in the market, I'm wondering if its worth buying a DAC -  a used Bryston BDA-1 in particular, in order to improve the sound quality. Or, you guys think I'm better off getting a new(er) player, for example an Oppo, and replace the CD player altogether. Thanks.
hard to say w/out knowing what transport it uses, and the untangling myth form actuality

a new OPPO will be $500 and have a warranty, so...

or a used Oppo would be less
