In all fairness Amir you should have measured DC output from various power supplies using AP balanced input with the wide sweep. Do this with load present and unloaded and specify conditions for each.
Though my personal experience measuring audio gear with various power supplies (12V, 5V... as well as usb filters) using AP mirrors yours. Very faint difference if any. Though I suspect there maybe some gear that is sensitive. What people hear is completely irrelevant though. If they hear that difference you cannot take it away...
