Cartridge Loading- Low output M/C

No harm for your cartridge at whatever loading, you can ignore manufacturer recommendations if you like the sound using different loading. You can start from 47k Ohm to completely unload your cartridge, then you can try 1k and then 100 Ohm or vise-versa.  

@chakster Thanks for that. I too an considering an Ortofon Cadenza Bronze but with a different pre-amp. These settings had me a little concerned but is seems we can change the loading to suit what we hear?

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. 

@hdm 
I would most definitely agree on your last sentence.
When I changed my cart to a zyx my initial setting ended up being 470ohms as it sounding the "best"
However after some break in the "best" was actually too bright and glaring but at first it had seemed to be by far the best choice.
Now running at 100ohm.

However there is not really anything to hurt by trialing different loadings and just let your ears be the judge.
It does sound like you will end up on the lower end of the spectrum but feel free to play, it will not hurt anything much bar your ears!
