will i notice a big difference if i upgrade from my MOTU 828 (mk1) to an RME multiface (mk1)? i produce electronic music and don't do much actual recording. i can buy a used multiface for $400 however i will then need to purchase the expresscard ($600!! new and i cant find it used anywhere) so the overall investment will be about a grand. is the improvement in transparency noticeable enough to drop a grand?
