Lew, Pat: In my view (and experience), the issue of cartridge loading primarily concerns what the phono stage can tolerate, and then as a lower priority what the cartridge would be most happy with. Put another way, what is commonly talked about as "cartridge loading" should probably more usefully thought of as "phono stage input termination."
To cut to the chase, the Connoisseur has been designed so that it is quite tolerant of loading across a broad range of cartridges - but the same is not necessarily true for other phono stages. With the Connoisseur, I happily run any of my own cartridge designs at 10kohm (used to be 47kohm) without feeling the slightest desire for heavier loading, but with most other phono stages, I find that something between 330~120ohms sounds better.
For a technical writeup as to why this can be so, please see Jim Hagerman's article at www.hagtech.com/loading.html. Some time back I wrote a much more detailed post on this same topic on Audiogon, and I wish that I could simply link to that, but I don't know how to find my own post! (^o^;)
