Test WIIM pro+ with different power supplies

[RAAM]

Thanks for more info.
This still leaves the door open for further speculation which may or may not pan out. It still could be the iFi or the WIIM unit but it seems more likely the iFi PS might be at fault. I have not read any other posts concerning the issues you had though I might of missed something on another thread, etc.

I had a great results using the iFi PS on the Pro + but only used it a couple of days then bought the Ultra.

The way to make a final determination, which you would have to have the PS on hand, would be trying different cables to see if any changes to eliminate a cable that might not interface the same as the ones you used. Also having a second iFi PS on hand and even another WIIM. It seems you are not going to be able to do this so just something for others to consider at this point.

I would not be posting about this if not for having a positive result when I tested the same model iFi and WIIM.

The final word I would say is if you are happy with how things are now then just enjoy the music
