i have one and i really like it!
the compressor is really gental! can't pump! which is good!
preamp/Eq are really quiet!
the preamp itself is trying to be a non coloring, but for non coloring natural sound... Grace 101(personally i think it's not for hard rock kind of stuff) is a bit better
but with imp selection (more flavors), and saturation(which i dont really use it) and a decent EQ + a better look!!
... to my ears, Eureka is more detailed and natural sounding than Maudio and all the lowend Focusrights
