I think you have that backwards. Dynamic mics generally require quite a bit more gain than a condenser. And when an interface preamp is spec'd out with 50db of gain that generally isnt all good sounding gain. Im by no means saying this isnt enough gain, because it is in most applications. On a quiet source with a large dynamic mic like a SM7b for example, it could get nasty sounding when the preamp is max'd out. It looks like a handy piece of gear though.
