Your advice is contrary to everyone else's.
One of the big advantages of the Gungnir Multibit is the custom closed form oversampling filter. Its output is correct at every point.
Comparisons have been done of the Jriver upsampling vs Schiit's closed form oversampling filter and the Schiit internal filter was found clearly better.
Note that minor inaccuracies can give apparently "improved" sound (much like boosting the treble can sometimes make recordings sound clearer).
All Jriver Output Format settings should be set to "No change" (except the ones below 44.1, and above 384).
hey, ymmv. welcome to the internet and the world of opinions.
