Well, I have to inform you that cartridge loading is not a matter of taste. Nor is it "controversial" or arbitrary. And the person who replied to your inquiry is rather less than knowledgable (to say the least!) There are many threads on Agon that go into this subject in detail. After you decide on a new cartridge, you'll want a more extensive explanation I'm sure.
Suffice to say that I've never heard or heard of, a normal (meaning not a "high output") moving coil cartridge that performed optimally at 47K ohms.
Many of the high output moving coil cartridges do work with 47K ohms, because they were specifically designed to do so. This is partly for convenience, since most people buy them to use with dedicated MM phonostages, and generally, they do not come with loading options because MM cartridges don't require them.
