Load Settings Help: Luxman E-250 and Koetsu Black Line

Hi Folks, I could do with some help as I don't understand load impedance or capacitance settings.  

I have a Luxman E-250 for my phono stage which is connected to a Michell Gyro SE with a Tecnoarm 2 and a Koetsu Black gold line cartridge mounted on the arm.  This all feeds a C900u and a M10x. 

The settings on the E-250 are default but I feel there is more to be had with the sound based on some other similar setups i've heard.  Could I get some recommendations on load settings?

The only way to load a cartridge at 47k on the e250 is to operate it without the transformers in circuit, so in MM mode. In MM mode, the gain is fixed at 38db, the output of the cartridge is .4mV. I doubt it is enough gain.

I did not know the specs on his phono pre and was/am going on the assumption that he could use 47K with a 60db gain as I can. My mistake in this particular instance. .But the idea is still appropriate for those who’s phono pre can load 47K with the MC gain. I have done this with several cartridges.

But considering that the OP may be somewhat new to MC cartridges its good that you pointed this out.

Thank you all for your help.  Clearly i've got some more reading and testing to do.  If that doesn't work out I'll be on the search for a new preamp.

Some quick testing, setup sounds best (for my ears at least) on 100K.  Sound is pretty neutral, lacking some low weight on some tracks/records.  

I like the tone of the cartridge and i'm pretty set on it, does anyone have alternative recommendations for a preamp to match the cart?
