$2,000 Used CD Player or Modified Oppo 105

I am looking at picking up an Oppo 105 to run directly through a Parasound P7 into a Parasound A21. My question is would I be better off buying a used Redbook CD player than spending an additional $2,000 in mods on the 105 to produce better 2 channel analog sound?

What would be the best used Redbook CD players up to $2,000 price range if this is the best course to follow?

All comments are much appreciated.
