Which should I buy to eliminate PC motherboard noise while keeping sound quality preserved?

Dunno, but nobody at home needs a re-clocker, and the other seems to be a common or garden USB DAC....

This is what I have been using for nearly 20 years and sounds fine. I paid $15 for it back in the day. I need a second adapter, so I am checking out the options.

Is this one overkill for connecting a mini pc running Daphile USB to SPDIF? Compared to say this one? The DSD support may come in handy.

The DSD support would require having the USB IDs of the device registered in linux usb audio driver quirks for the DSD https://github.com/torvalds/linux/blob/master/sound/usb/quirks.c#L1979-L2085 . I could not find that device USB ids online (many reviews, but reviewers do not know that USB ids are quite an important info). Also the SPDIF output would not transmit native DSD, it would have to be wrapped to DoP, IIUC.

IMO there is no reclocking in that device, it looks like a standard XMOS UAC1/2 async device with standard set of three crystals - one for USB and two for async audio.
