Hello cantorgale, with the M Scaler the output to the DAC should be up-
sampled regardless of input rate.
All upscale is done after Roon (source bitrate).
Roon only lists original file resolution.
The filters are a matter of preference with Incisive ( white ??? ) being the most resolving.
The filter settings are selectable on the fly. (whichever effect is preferable).
Generally the filter effect is more for overall system sound balance but you use any setting with any file.
You should be using the DAC setting (Pre Amp mode, Amp / Headphone,
and DAC).
The M Scaler could also be set at any level or selected for max output.
Also check settings in Roon for output.
