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
