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

Thank you all for your input, much appreciated.

I will try and adding a resistor to the RCA input (I presume I just attach on end of the resistor to the positive and one to the negative). Is this correct?

To get 100 Ohm loading on the cartridge (starting point) what size resistor do I need to add at the RCA input? Is there a calculation table for this as this is starting to go above my head now.

Thanks a million.

I'm running a Lyra Titan i and Transfiguration Orpheus wide open (47K ohms) through a Manley Steelhead with terrific results.

YMMV

I use Lyra Titan as well but much better of with 100Ohms.

"Better" depends on your other components and personal taste.

It's that simple.

Get a couple rca y adapters (2fmale to 1 male) and some cheap rca connectors from radio shack. Make yourself a few load plug ins by soldering resistors onto the connectors and the y adapter will put them in parallel with the input. This is a cheap fast way to sample different loading. Use good resistors. If you find something you like you can fashion something more permanent or just use the jig. There's no hard and fast rule its different with every cart, pre, system, combo.
