Cartridge Loading- Low output M/C


I have a Plinius Koru- Here are ADJUSTABLE LOADS-
47k ohms, 22k ohms, 1k ohms, 470 ohms, 220 ohms, 100 ohms, 47 ohms, 22 ohms

I'm about to buy an Ortofon Cadenza Bronze that recommends loading at 50-200 ohms

Will 47 ohms work? Or should I start out at 100 ohms?

I'm obviously not well versed in this...and would love all the help I can get.

Also is there any advantage to buying a phono cartridge that loads exactly where the manufacturer recommends?

Any and all help would be greatly appreciated.

Thanks in advance.

My preamp has 60 db of gain for MC and seems adequate.  I would start there and see what ya think. 
Definitely try to stick to 60db gain if at all possible.
The higher the gain the more chance of inducing background noise, you know the hiss you can hear at the speakers with no record playing.
Good luck and trust your ears
In my experience, a very low resistive load, which puts a correspondingly heavy load on the cartridge, acts like a tone control, which is to say that as you approach the internal resistance of the cartridge itself, the treble is rolled off progressively and eventually some gain is lost to ground.  In theory, if the internal R of the Cadenza is 5 ohms, the minimum load resistance would be around 47 ohms, or 10X that of the cartridge, as someone else already suggested above. But I have lately found that even LOMC cartridges sound their best when the cartridge is essentially un-loaded, at 47K ohms.  The treble is more "open" and airy.  Dynamics are also improved vs more traditional values of load resistance.  (LOMCs with low internal resistance, like the Cadenza, are traditionally loaded with 100 ohms, a set it and forget it value.)  Ralph Karsten (Atma-sphere) points out that not all phono stages behave properly when LOMCs are presented with a 47K load, so maybe I am just lucky.  I agree with the person who said that the "best" choice is phono stage AND cartridge dependent.
