Smsl sp200 with smsl m200?

So I’m planning on buying a DAC for the sp200 will the m200 be good or maybe I should go for another one?
I have my eyes in the smsl su-8 or do you guys have a recommendation in that price range?

I am curious too because my original combo was the su-8 + sp200 but now I learned about the m200 and the m300 mkii, I don’t know how good are the new m series.
