MC loading at 47K

Hi All,

Just after some expert advice from your good selves if I may. My current system is as follows:

Musical Fidelity KW550 intergrated amp which has a MM and MC section, both loaded at 47K. The only difference between them is the step up voltage.

My turntable is the Rega P9 with Ortofon Kontrapunkt A.

Looking at changing my cartridge but honestly cant decide between MM or MC.

My music taste are as follows:

Reggae
Soul
Female Vocal
RNB

No classical or jazz.

So what should I choose based I'm only limited to a 47K loading. I was thinking either of the below:

1. Ortofon Jubilee (MC)
2. Ortofon 2M black (MM)
3. Clear Audio Maestro (MM)

Is there a down side to loading up a MC so much?

Thoughts please...thanks

you might experience very thin sound and lack of holography.
the realistic load impedance to try is sub- 100Ohms. You can solder 100Ohms resistor in-parallel with 47K resistor or try different resistors using aligator clips.

I use a Benz Glider SH (2.5mv output) into the mm input loaded at 47k. The phono pre is Vacuum State Jlti. The frequency balance is natural and not at all bright on top. I obtained the same results with the Musical Surroundings Phonomena. However, this cartridge sounds like crap fed into the tubed stage of my VAC preamp. I don't know why this combination doesn't cut it.
The Benz sounds great on my classic rock albums, jazz albums, and vocalists such as Linda Ronstadt and Emmylou Harris.

The impedance of Benz Glider SH is more than 10x higher than Kontrapunkt A. If you try to load with 1.5k you might like it better.

Since you are stuck with 47k I would go with the Ortofon 2m black. I have the bronze and it is an excellant sounding cartridge

Loading a MC at 47K is a recipe for thin sound. I would stick with a MM cart if you are married to 47K. But...why are you married to 47K?
