ok, DPLL to minimum value? and volume -5 is that okay?Technical explanation of everything is quite impossible, backread this thread and you may find some information (even if probably not understandable since they are not explained for whom doesn't know the topic)
What you should know, is that you need to select a filter for PCM and leave it as it is, since it will work for 100% scenarios.
Soundcolor may be selected as you prefer, for DSD filter is ok the default, and you can lowe DPLL to minimum value, raising it if you hear issues
That's it
