Look at Audiofeil's answers very closely. Perhaps I am mistaken, but your OP suggests that you don't understand how loading a MC cartridge works. Running a cartridge into a "wide-open" 47K load, means that the cartridge sees less resistance than at 200, 500, 1000, etc. ohms. My experience with many different cartridges, and preamps over the years has been that I tend to prefer 47K loading for MC's. Anything much lower than that has usually (not always) made the cartridge unnaturally thick sounding, with loss of fine inner texture to the sound. As Audiofeil says, it is really a matter of personal taste in the context of your particular system. If your system tends to the bright/thin side, you will probably prefer a lower load value.
