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.

To a great extent the loading you select will be user and system dependent and based on your subjective preferences.

That being said, internal impedance on the Bronze is (like many Ortofons) quite low at 5 ohms. In theory the 47ohm setting should be ideal but you could experiment all the way from 22 ohms up to 200. I'd be inclined to set the gain at 60 dB on the Koru. 

I'd probably start with 47 ohms and stay there for an extended period of time, especially while the cartridge breaks as it will probably be a bit steely and aggressive for the first 20-30 hours, maybe more. And then experiment from there. 

Bear in mind that the most "impressive" setting may not be the most natural or "best" setting. What grabs one initially can be irritating or fatiguing over longer periods of time.

Wynpalmer4:  (or anyone else that might have an opinion for that matter)

I am curious to know what your thoughts might be regarding current mode phono stages that use a low impedance input that supposedly presents almost a short circuit to a moving coil cartridge.

My Aqvox does this so loading is literally taken entirely out of the equation as it is not possible to adjust loading in this mode. According to designers/manufacturers of phono stages this approach results in better performance.

Your thoughts on why this may or may not be a good idea?
