Eddy - Thank You. I think I get it. I did not know which of the wires in an intact USB cable were carrying signal vs power. Sounds like red & black carry power so those (red to red & black to black) need to be soldered together to join the leg from the 5V power source to the USB cable running from the MAC to the DAC.
Static noise help please
Recently just notice Static, hiss, popping sound(I don’t think I hear that before but I might be wrong) from both speakers when volume alway down with music off. Happen only when connected usb from iMac to Schitt Modi 2 Uber DAC. Static noise disappear after unplug either end of the usb. I am using temporally cheap 15 feet usb a/b cable. Pre amp is ARC LS7,ARC VS60 amp,and Sonus Faber Venere 2.5. Any advise?
I swap from ARC setup above to Cary SLI80 interested amp and used the same usb cable and the static noise was gone. So I think it is not the usb cable problem. Is that possible static noise come from tubes?
Regards,
Eddy
