By contrast, my PS Audio DirectStream DAC plays DSD only in DoP mode (except for its I2S inputs, which purportedly accept native DSD). As such, I would assume you do not need to convert DSD to WAV or DoP, in the Melco or via MinimServer. I am listening to a DSD128 file on my Melco HDD as I type this (Twonky > USB > DAC), with the Melco set to "DSD over PCM priority mode." It is working as intended and sounding quite good.

Which version of the Melco firmware are you running? I have v3.72 and I do not see a way to switch off Twonky.

Thanks.

I am running 3.72 and cannot see a way to switch off Twonky from the user guide. There is a way to do it by editing a MinimServer config file that Simon has documented on the MinimServer Melco Install pages. It is quite easy to do.
As for my DAVE and "Native" DSD, I remain confused! I have Audirvana on my MacBook and that detects if a USB DAC can support DSD "Natively", i.e. non DoP. My little iFi Nano supports it but not my DAVE and that appears to be confirmed by the display on my N1ZH. So I remain unsure as to the precise data transport system used between the renderer and DAVE.

Confusion resolved! Chord DAVE is Native DSD when in DSD+ mode. When in PCM+ mode it is DoP. As the majority of my music is PCM and it takes 20+ seconds to switch modes, I use PCM+ mode. So my tests on this DSD128 file were carried out using the Melco DoP facility.
