Native DSD support via USB

[Devon]

I bought a Wiim Ultra for DSD files, unfortunately the files downloaded from the DLNA server are converted by Wiim Ultra to PCM 192/24. Is there any way to add full DSD support via USB output? Are there any hardware limitations of the Wiim Ultra or is it just a software issue?

Not sure what you mean - both support DSD playback, see either the WiiM Uktra or WiiM Pro Plus firmware pages where you’ll see DSD support mentioned e.g. https://faq.wiimhome.com/en/support/solutions/articles/72000631650-wiim-ultra-firmware-release-notes

They do transcode it to PCM though.

Or process them in the DAC and output analog?

I think they still convert to PCM first or volume control wouldn't work.

That converts the DSD to PCM. The idea is to have DSD played as DSD. The DAC chips support that but Wiim has not implemented it.

What's I mean is all playback is via transcoding to PCM, not native DSD, despite the DAC chipsets used in the Pro Plus and Ultra being capable of native DSD:

Playing DSD Audio Files on WiiM Devices

All WiiM devices, except for the WiiM Mini, support DSD audio file playback. These devices convert DSD content into PCM data for playback, with a sample rate of up to 192kHz. Here are the ways you can play DSD audio files on WiiM devices: ...
