Just posting this here in case anyone has a similar setup and issue, and thanks
@ArthurPower for being helpful and prepared to send a replacement if there was a defect.
I was getting transformer hum on my Silver Fox and started troubleshooting what may be causing it, only to find out that PSM156 - iFi Supanova to Aquarius in one outlet with Silver Fox in another was a REALLY bad combo making the hum 4x louder, took out the Supanova and it was way quieter, however I could still faintly hear it, so that left my source, my PC.
Moved it to another outlet and it is gone, imperceptible, would probably have to open up the amp, and place my ear quite close to the transformer to hear anything.
That being said, it looks quite nice in black.
