CD player - Esoteric DV50S 
New, it sold for $6,000. You can now pick one up used for ~$1,000.

Even cheaper is the Sony S9000ES that you usually find for under $300.

As for DACs, the Teac UD-501 can be found used for ~$500. In the higher end, you can find the Lampizator Amber for ~$2,000 or the Bricasti M1-SE for ~$5,000 (50% off new).
