So how many use MM cartridge and intend to keep it that way ?

1) Grade gold 1 with paratrace tip which I potted with wax.
2) Shure m95he
3) Empire 4000 d/iii
4) Empire 875
5) Rega bias 2
tables are a Union Jack rp3 Audiomods arm. And an Empire 208 Sme m2/9.

I love the body and weight  you get from some mm and mi cartridges, plus mid range timber. A good stylus can make a world of difference. I did own a Cartridge Man for a while, but needed some extra funds at the time so sold it. It was smooth with a incredible sound stage and detail, but did not produce the bass slam I like in my system. 

I have only used Grado carts. I briefly tried a Dyna 17d3 through one of Bob's Devices. I much preferred my Sonata. I thought about 2500.00 retail for the step up and cart combo would give me a good mc taste. Price not including the IC. I currently use a Reference1 that sounds really good to me. I think about trying some of the above mentioned vintage mm. One day I hope get to them. For now my new Belden 8402 IC has made for some really nice music coming out of my system. Iow, I don't plan on messing with a cart change anytime soon. 

When I hear someone say "bass slam", I don't quite know how to take it. Either they are talking about bass that should be reproduced as recorded or about exaggerated bass that they like.
'Messing' with interconnects can be very beneficial even if not exactly free.

It's true sometimes it's an exaggerated bloom in the bass region, but other times I begin to hear more detail and a stronger mix from the bass lines. Example would be Zeppelin JPJ and stand up bass in jazz even from a very low cost cart as a Shure m35x even if it's lacking in other areas.
