If you don’t mind my asking: finally what?

Probably referring to the conclusion of the article:

For DACs, there is almost no difference in sound quality depending on the type of power supply used.

Good to see another confirmation, of course. Small sample size of DACs, though.

And calling the power supplies “better” seems a bit of a misnomer considering the test results. The $2.20 wall wart works as well as the $170 linear power supply, as one would expect.
