Feature request, in the order of descending preferences. Thank you very much for your anticipated related efforts:

(A) Implement a native DSD playback, or native using DoP. Note: If that may significantly reduce the DSP capabilities of the Ultra, that would be understandable. If that may not be possible, then ...

(B) Add the following to the Ultra's current DSD-to-PCM capabilities:
- Remove the ultra-sonic noise starting from about 30 to 35kHz and up. Note: The ultra-sonic noise is currently present, and can only make the downstream equipment work harder without any benefits.
- Increase the signal loudness by 6dB, or close to 6dB. If with 6dB the avoidance of the signal clipping may be difficult, make the increase of the signal loudness user-selectable, e.g. +3dB, +3.5dB +4dB, +4.5dB, +5dB, +5.5dB, +6dB.
- Convert DSD to PCM with the 88.2kHz or 176.4kHz sampling frequency, rather than the currently used 192kHz.

While some WiiM personnel do surf the User Forum on a frequent basis, the Official method to post a Feature Request is via the WiiM Home App (More / Feedback). Go for it!!
(I've an interest in DSD Playback, too.)
