I have the original M0 which you can't get new anymore, not the Pro version. This is my super minimal/portable/fun setup, not high-end/sound quality focused.
With that said, the M0 pairs with this MM/Velvet/Seraph combo wonderfully, just enough power to sound good but do note MM is very power hungry, a proper dongle will sound much much better, e.g. ifi Go Bar. The newer Pro version has strong power output, should power the MM better (in theory).
I've a Hiby R3 II on order, very curious to see what it sounds like.
Oh, the Seraph cable is highly recommended, well built, soft, light, not crazy expensive and pairs with the MM perfectly, in looks and sound.
