Yes, using the Mac with the DAC directly connected to it via USB (according to your original post) only DSD over PCM was available to you.
However, with your Eversolo streamer you may use native DSD up to DSD512.
Therefore, if you want the highest PCM to DSD conversion, you should not use DoP since this will only offer DSD64.
This is important since the Nucleus ONE will handle conversion to DSD64, but probably not DSD512.
Elsewhere you (@Stacey_King) said you did not want to use HQPlayer.
Given the confusion, can you explain why you want to convert PCM to DSD. Whilst this should not be a debate about the pros and cons of each format, it would be helpful to understand your reasoning.
