Cost vs quality of audio result and dynamic range!
A dual DAC Wolfson less then 1 Euro in packs of 10! 
1.4euro in single units.

No filters, no external drivers if you
chose one with inbuilt headphone driver.

The minuses are the interface and MCLK driver but can be
solved by fiddling with SPI driver software i hope.(crossing my fingers)
