Hi there:
I just purchased both a ZD3 DAC connected to a ZA3 which I have connected to my passive speakers and my newly acquired subwoofer (KEF KC62). When the USB cable is connected to my computer, the subwoofer makes a constant low rumbling or what might be described as a thumping sound. When I unplug the USB cable it goes away.
Even weirder, if I turn off the ZD3, which then turns off the ZA3, the noise is still present, unplugging the USB cable fixes this, but usb audio from my pc was the main reason I went this route haha.
Any ideas, I'm heartbroken the new fosi equipment seems to be doing this.
