I have set the sample rate of the digital output to 96kHz, and the Dacmagic shows everything incoming to be at 96kHz. However, for most of the stuff my music player (I use Vox) indicates that the material is recorded at 44.1kHz. Does the sound chip of the Mac perform upsampling in this case? Is this potentially detrimental to the sound quality? What is the best way to send the signal to the DAC?
