Essentially these programmable reconstruction filters are nothing that WiiM has done. They are part of the architecture of the ESS SABRE DAC that WiiM is using. See docs on their product line-up:

SABRE Audiophile DACs – ESS Technology, Inc.

The question here is if WiiM makes the filter selection available in the firmware or the app.

Sure I know, but thanks
