Exploring the realm of DAC Digital Filter Types within the WiiM Pro Plus app, users debate the impact on sound quality.
Summary
- Choosing the best DAC filter type is a matter of personal preference.
- Various users claim different filter options offer negligible differences in sound.
- Some prefer slow roll-off filters for improved performance.

I normally do slow roll off as it improves the time domain performance. There could be a bit of high frequency roll off as a trade off…if you’re young enough to hear above 15khz.

Pick the one that sounds best to your ears. If they all sound the same, then you’re done.

I noticed the other day that my Marantz cd6007 has two filter options too, but they sound exactly the same to me.

Go for the slow rolloff option to minimize phase errors and phase shift that messes with imaging and soundstage.

Aaah the good old DAC filters choice…
I will rub my eyes the day I hear of anyone consistently noticing an actual difference between filters.

This menu simply should not be shown to users at all. It is the manufacturer’s responsibility to make a good choice, and not allow users to mess this up by offering worse options that suffer varyingly from aliasing, lack of flatness in passband, or phase distortion. The correct choice is “Sharp Roll-Off”, in my view, and it is the textbook oversampling DAC.
