a dilemma for cartridge/phono stage combination

the cantilever of my Benz-Micro MC-20E2 "High Output" cartridge was broke.
fixing it will cost more than a new one.
benz offered me what they call  repair/exchange with a nice 40 % discounted price.
i'm thinking to go on it.
my dilemma is between a high output cartridge like mc silver, which is kind of equivalent to the one i had, or to the low/mid output.
i'm working now without external phono stage and with my 2.0 mv that i had i used to raise the volume of my intagreted amp not more than 11-12 clock.
i read that generally low output mc are better quality that the high one's.
another cartridge that i have with 0.4 mv ( monster cable alpha 2) gives me very thin and dull sound, so i guess i will need an phono stage for the low output cartridge.
if it'll give me a real sound improvement i am ready to spend on a phono stage.
i know that benz micro also sell those. 
the models i consider for my budget limit are :
Benz Micro MC Silver
