As further comment this is sophisticated nulling software. Results show what corrupts nulling the most among good DACs is differing phase response in the upper frequency ranges. This comes from the differing filters. What is known about this indicates humans do not find phase differences in upper frequencies to be audible. The software above can even fix that for you in a comparison and once you do good measuring DACs simply don't result in very much residual difference of any level that could be heard.
If good measuring DACs sound different I would say it will be in the filtering. Everything else is beyond reproach in terms of audibility.
