Hello, I wanted to see if you ever found a solution to this. I purchased a Mac Mini to be a dedicated music server and have the SA-11S3. I downloaded the USB driver from the Marantz website and connected the Mac Mini to the SA-11S3 via USB cable to the rear USB port. I set the input to PC and was able to get great audio for probably 5-6 seconds and then it became very distorted, scratchy, etc as you described. Any assistance would be greatly appreciated.
