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

Benz Micro ACE-S low

Benz Micro ACE-S high

my turntable and arm are well tempered.

i'll appreciate very much some guidance .

what is SUT, phono preamp?
what model of Bellari?
think that it’s important to have impadance control etc.
,no?
there is the VP129, 130 and those here:

saw some of them sells on ebay with lower price.
You can get a Bellari VP549 phono stage and MT502 step up transformer. This combination plugged into the aux input of your integrated amp will give you superior sound quality (SQ)!
The Monster Cable Alpha 2 is a very good sounding mc cartridge! It will work just fine with the Bellari step up transformer (SUT) straight into the phono input on your integrated amp! I still recommend adding the Bellari VP549 phono stage (to replace the internal phono stage in your integrated amp).
As for a better (newer) mc, I can recommend the Hana SL. It has a superior stylus (Shibata) that will enable it to sound better than either the Alpha or Benz Ace MC's! More detail from your LPs and less wear!
