Loud fizz with brand new Parasound Halo Integrated amplifier


Connecting my MacBook Pro to my new Parasound Halo Integrated amplifier. The connection is from MacBook’s USB A into Halo’s USB B. Music from iTunes plays but there’s pretty loud distortion/hissing. Not during the quiet parts of songs, though. Only when certain music frequencies play. Does anyone have an idea of what’s going on here?

When I plug a small Fiios headphone amp into the Mac’s USB A and listen to iTunes through headphones, no issues. So I don’t think the USB port of the Mac is malfunctioning.

The USB A-to-USB B cable is not the culprit, either. It’s a new Audioquest cable, and when I use my old cheap cable, the problem still exists.

BTW the Halo plays CDs beautifully. The fizz is apparent only with music through its USB. Haven’t tried the Halo’s phono input.

I’m hoping there’s some setting that I just need to adjust to eliminate the USB fizz. Otherwise, I will return/exchange the Parasound Halo.

When I had my Parasound Halo, it came with USB drivers for my  windows based computer.  Never ever had a problem.
