You mean just play DSD flie without doing anything?
What is mean bitstream instead? Can you please explain me
There are 3 ways to play DSD files. One is to have MC convert the DSD to PCM, which allows MC to apply its various processing options (DSP) and to control the volume. This is useful if you want to use those options or if you DAC does not support native DSD. The second option is to send straight DSD to the DAC. Because of the form of DSD MC (and most software) cannot add anything (like DSP options or volume control) to the DSD data. Some DACs accept straight DSD, but many do not. So there is a third option - to pack the DSD data into a PCM file format (DoP format) and send that to the DAC. The DAC then pulls the DSD data out of the PCM format and plays the DSD. Note that this simply uses the PCM data stream format. It does not convert to PCM data. Using the second or third option is dictated by what DSD format your DAC supports.
In the context of DSD, bitstreaming simply means sending the DSD to the DAC (either native or in DoP format) without converting to PCM.
Bitstreaming and DoP are set in Options - Audio.
You can also have MC convert PCM files to DSD and send DSD to the DAC. This requires a fast CPU, as the PCM to DSD conversion is very CPU intensive. This option is set on the DSP Studio page, under encoding. You get to DSP studio from Options Audio or from the Audio Path icon, upper right on the main screen, next to the Shuffle and Repeat icons.
