It will work absolutely fine. Just configure the device in the MIDI control panel.My question is, what performance should I expect from a 2018 Mac Mini?

What playback software do you plan on using? There are several options.
Many who have compared feel a PC works bettering playback. Might be true if using iTunes for playback.
A Mac gets around the driver issues a lot of times. And driver breaking with software updates.
I use a Mini that is several generations old. Lots of RAM and a large SSD. I think the last model that allowed swapping both. Works great.

Looks like there's a new kid in town

Well, the Schiit AP ones have generally been quite like Amir's so that's a good starting point.Oh, yeah. We need measurements.

I bought 2 months ago Modi 3 and I had Magni 3 little bit earlier, so I sold all creative cards, such as G6, because Schiit has so cool sound, no drivers needed, very good bass etc. even do not wanna explain all details, I do not like only Magni power supply)

Crystals which are the source the clock in any system are mechanical resonators based on the piezo-electric. This means that crystals have a sensitivity to mechanical vibration. The sensitivity is a function of the type cut of the crystal. 25 years ago this was an issue because most systems used lower cost crystals which were more sensitive to vibration. The act of potting on of these crystals in resin reduced the sensitivity of the crystals. Many adopted plls which reduced or masked the sensitivity by spreading the spectrum of the induced jitter. That plus the adoption of better crystals made the problem less audible. It is far less of a problem today than it was then. But it could still be audible. The problem is no one is measuring it today.Dear @amirm ,
I just saw that on youtube.
Would you please, if you still have the Modi 3 on hand, MEASURE this statement?: "Modi 3 sounds a bit better"
Thanks.
Fine. And how do you measure such a "problem" ?But it could still be audible. The problem is no one is measuring it today.

In the old days I connected a pll to the clock and monitored it. I realize that could wander into the destructive testing. One way might be to use a vibration plate. In my experience crystals seemed to be sensitive to midrange frequencies, middle of the piano, which is beyond most cheap vibration plates.Fine. And how do you measure such a "problem" ?
Jitter? Would be surprised if I measure anything out of margins under common domestic "vibrations" (idea of extreme scenario: blasting my speakers at 90% volume near some DAC).
