DACs change with new technology more quickly than any other component except for computer/streaming sources. Also, due to Moore's Law, the cost of the new DACs with newer technology is often less expensive.
This is one area where it might be wise to buy a new or near-new component, unless there's some specific feature of the older DAC chips that interests you, i.e. non oversampling or non upsampling.
