Arthur, DACs have been at a state of technological maturity for quite some time now. Measurable differences certainly still exist, but typical ones, such as those internal to your equipment, provide levels of frequency response, noise and distortion which are audibly transparent. No audible benefits result from adding an external DAC.

One caution in viewing comparisons sometimes seen elsewhere is that if the associated electronics in the new DAC result in a slightly louder level with no change in the settings, this may be misinterpreted as better digital/analog conversion rather than simply the louder sounds better factor which often misleads when not compensated for.
