I have found that 200 and 400 seem to be the best sounding to me. It would be nice if there was something in between.
I have some nice Kimber select cables in between the pre and the phono stage. I will try different cables to see how that affects the loading.
Thanks.

47 Kohm is equivalent to 47,000 ohms (not 4,700); this is the typical MM input.
I wouldn't worry about it. You can run MC carts into 47Kohm, and sometimes this is fine, but the sonic results will be very dependent on both cartridge and phono stage (and their complex interaction). If your results are "fine", then you get the added benefit of reducing sensitivity to phono connector/wire quality, which is why some recommend these higher ohm values for MC carts (the Benz PP-1 uses a fixed 22,000 ohm input for this stated reason).
That said, I've not yet had a situation where I've ended up with more than 200 ohms on an MC cart. The mid-output MC's (e.g. the Clearaudio) would typically be fed into a range of 200 ohms to 1,000 ohms.
