Audirvana - How DSD is streamed
Last Updated 2 years ago

The following is from Audirvana in relation to DSD/DoP:

"To listen to DSD files from a DAC, Audirvana Plus transmits the DSD files to the DAC using the “DSD over PCM” protocol that requires markers, and using this protocol requires twice the bandwidth over the native DSD signal only. In order to get the best possible result, you need to use Audirvana Plus with a Native DSD DAC. However, if your DAC is not DSD compatible, Audirvana Plus will perform downsampling to PCM using a very high quality 64 bit algorithm.

Please note : The “DSD over PCM” protocol requires markers to identify the signal as DSD, so using this protocol requires double the bandwidth compared to the native DSD signal alone. This can reduce the maximum DSD frequency that can be used with DAC by half compared to the frequency that can be reached under Windows. This may explain why a DSD 512 DAC can stop at DSD 256, and DSD256 DAC can stop at DSD128.
