Thank you 1KW for the suggestion. I tried the following two different connections, which still involve Mac Mini & USB:

1. Utilize another DAC:
Mac Mini --> USB --> Oppo 105D --> XLR (Analog) --> Preamp
Result: no noise.

2. Utilize another digital input:
Mac Mini --> USB --> Oppo 105D --> Optical --> MCD1100
Result: no noise.

I think these two testings ruled out Mac/USB as the root cause.

It seems to me the issue has something to do with MCD1100's USB input...
