While it is likely that this test will hold water in a large majority of systems, if you compare the same file//DACs with the same methodology in far superior system then the results will likely be different. YMMV.
There are two kinds of DACs:
Invisible. Transparent. Ideally Zero
audible change to any listener, through any system, including price no object, with any music.
Makes some sort of change some listeners may deem desirable and others may not. For me
alteration whatsoever is by definition undesirable. I don't want my gear to editorialize on the recording engineer's careful work to make the particular recording.
There's no rule people should seek out perfect ones although I certainly want just that. I want to hear what the recording artists intended me to hear and not the arbitrary adulterations of an imperfect DAC that has no idea what music I'm playing at any given moment and instead inserts a non-defeatable, fixed, arbitrary alteration to everything passing through it. But that's me. YMMV.
The pursuit of music reproduction accuracy has a name: "high fidelity". The very highest level is called "transparency", i.e. zero
audible alteration to the signal as far as the ear is concerned. This ABX test is a test for that.
