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

Some folks including Charles Hansen (Ayre) and the late Allen Wright recommended running all MCs at 47kOhms. I think Harry Pearson (HP) of The Absolute Sound recommended it too (don't know if he still does). I tried it and liked it with a Denon DL-103 although I'm currently running that one at 500 Ohms. I'm not sure but I believe the "thinness" will have to do more with the phonostage than anything else. If Musical Fidelity loads both MMs and MCs at 47K, they must think MCs sound okay that way.
Something that hasn't been mentioned: Anyone with a phonostage offering instantaneous load change comparisons like my Aesthetix Rhea will be aware that the audible difference as you go from sub-100 ohms to 47 kOhms isn't nearly as great as you might expect. Yeah, there's a difference (especially going from sub-100 immediately to 47k) but the incremental changes are pretty subtle.
