I have the fireface uc and in the pursuit of better audio fidelity I had heard about those ifi power supplies, which are marketed to supply clean power or something like this, that it somehow inverses something like with phase cancellation and thus makes the electrical interferences disappear.
I had bought one and had used it for some time with the fireface (of course same volt).
But now I switched again to the original power supply from rme and suddenly noticed that there is a big difference of how you hear yourself when talking into the mic or singing. It is almost as if it is more accurate with the original power supply, but with more interferences as it crackles when power supply is off but gain turned up.
Also, when I had gain on 44 on both supplies, the ifi delivered far less accuracy with the voice. The sibilances and breaths and plosives are far less annoying to edit out now without the ifi and the voice feels easier to edit.
Now I took a look at the ampere which the power supplies have and ifi has 1.8A instead of the 2A on the original fireface power supply. Can this be the solution? That the ifi has less ampere than the original ff ps and therefore is not optimal? I got carried away when I bought the ifi, but I really don´t think it improves the sound, I rather think it deteriorates it.
Can this be? Or am I just caught in this placebo audio effect?
