Can anybody define LOW OUTPUT...?

Hi. I'm currently pursuing the insanity of trying to decide on and purchase a really, really good used low output MC (only because it seems - in theory at least - that there's more detail to be had there). At any rate, my phono stage was designed for a Linn Troika cartridge (low output - 100µV - that was a MU - in case you don't have a mac also!) - yet I've been looking at some van den Hul low-output MCs that are something like 5-6 TIMES higher output than this - I'd imagine that would put the vdH at LEAST in the MEDIUM output camp. Am I missing something here? Can anyone APPROXIMATELY delimit (spell out for me) the boundaries of what is commonly considered low, medium and high output?

Thanks much.
