MC14 has special settings for some DAC's.
You will need to select 24-bit in DSP Studio. High end DACs seem to like 24-bit data. They don't like the default option "Present 24-bit data in a 32-bit package".
For the best quality playback with high-end DACs, use these settings (this requires Media Center 14.0.15 or later).
Options > Playback > Audio Use WASAPI Output
Inside "Output mode settings..." for WASAPI Checked: Open device for exclusive access Unchecked: Present 24-bit data in a 32-bit package
DSP Studio > Output Format Bitdepth: 24-bit Channels: Source number of channels Sample rate: Depends (with an outboard DAC, try "Source sample rate")
Known to work with Proton USB DAC and Benchmark USB DAC1.
