I'm currently ripping apart some high end audio measurement system (25 years old and limited to 500Hz-20kHz by software, so unfortunately not useful) - the ADC is socketed, the two DACs (AD1862) are soldered.
Since the manufacturer used only the very best parts available (Jensen audio transformers etc. pp.) and presumably knew what they were doing, it might have been a better choice (noise-wise) to solder them directly.
As the resolution of this 20bit DAC is much higher than your 14bit DAC, noise might in fact not be a problem, so I'd just use a socket. (I know I will use a socket for mine, once I get them desoldered - a true pain with a multilayer PCB and some groundig planes...)
