PS Audio PMG 512 DAC vs Grimm MU2 or Meitner MA3i with Roon?

I’m curious if anyone on here has compared the PMG 512 to the Grimm MU2 with Roon? I’ve had a friend lend me his MU2 and it sounds better than either the Innuos Pulsar or Eversolo A8 going into my Holo May KTE DAC. For those of you who care, the Pulsar is better than the A8 but I hate using the Sense software instead of Roon. I have also heard the Meitner MA3i in a different system and it is quite good and supports Roon but I have no idea how it compares.

I am trying to find a cheaper alternative to the MU2 that sounds as good and the PMG 512 with its Roon end point and built in streamer sounds like it might fit the bill and it has the added benefit of supporting I2S which neither the MA3i or MU2 do and I like to connect my CD Player with I2S.  The MA3i doesn't support I2S but it does function as a Roon end point.

Has anyone had actual experience comparing these three high end solutions?

And can all the trolls that want to lecture me about how DACs and Streamers have no sound go pollute somebody else's thread.
