I'd recommend the MCP4921/4922 (1 or 2 channels).
There's an SPI interface on it, so super easy to interface. 12bit audio on each channel, 2 channels if you get the 4922 chip.
And they're extremely low noise. You just have to (as I just found out) put a very low lowpass filter on the Vref pins, not directly connect them to 5v. I mean really low; I'm using one with a cutoff of around 0.03Hz.
