The Schiit Yggdrasil manual FAQ section states, "How should I set the input bit depth and sample rate? Set it to the native bit depth and sample rate of the music. Yggdrasil will take care of the rest." This can be done on a Mac by opening Launchpad - Other - Audio MIDI Setup and setting the format to 96kHz/24bit or 192kHz/24bit, changing the "Sample Rate Indicator" light on my Yggdrasil to 48 X2 or 48 X4 respectively. But then this light does not change when I stream lower quality music. Do you routinely change this setting every time you change music quality or do you just leave it at a higher input quality? I did a Google search and found a recommendation to just leave it at the higher sample/bit rate, and that any up-sampling does not adversely affect the audible sound quality. I will play with it over the next few days, but I was curious what other Yggdrasil owners thought. Thanks!
