I have a very similar system. I use the 2nd ethernet port on my Zenith Mk.3 into the Ma3i. This forces the system to use the integrated Meitner streamer which is a substantial improvement over the Zenith streamer. I've compared both by switching between USB and Net on the Ma3i and having the Zenith connected by both USB and ethernet cables from the Zenith. Not sure if the mini allows this but, if so, it's worth a try. I have the same speakers, different monobocs though and Rel subwoofers.
