I loved the DAC 1 mk2 when I heard it and almost bought it even though I don't need another DAC right now. Prior to that I have also heard the Frerot with the upgraded matching PSU. It is also really great, especially for the price. I think Merason has a nicely neutral sound while somehow managing to sound more natural and organic than most other neutral DACs.
I have not heard the Reuss yet but I would be surprised if it wasn't also exceptional like the others.
