Yo Devilboy it's Dave from Renee's party!! What up B!! I think your problem may be with the USB2 going into the USB1. You can go USB1 into USB2 but can have issues with the other way around. Have you configured the Mac for the converter? When using USB on the Mac for audio you may have to configure the DAC. It's located in SYSETM HD/Utilities/Audio MIDI Setup. I think using the toslink is best for now because there is no setup for that. If you are wanting better converters try on of these http://www.mercenary.com/prsodrdatwoc.html or one of these http://vintageking.com/Weiss-DAC2-D-A-Converter or maybe one of these http://vintageking.com/Lavry-DA924?sc=18&category=500 The Weiss and the Lavry Gold can hook up directly to the mac via firewire.
Mac Mini USB output sounds "garbled"
In my smaller second system I have a Mac Mini with songs ripped into WAV with error correction turned on going into a dac via USB. Why does the music sound "garbled" or "crackled" most of the time? I run a composite output from a CDP into the same dac and it's fine. What am I doing wrong/not doing right?
