Altanpsx,
There are so many good cartridges out there and system matching and particular taste can be so specific as to make suggestions somewhat unhelpful. I have heard great systems using all of the major brands, and some you have not mentioned (e.g., Allaerte). To a significant degree, your choice will be a gamble.
I have had the luck of finding local dealers that allowed for reasonably long term auditions (one or two weeks) of the cartridges I chose. One dealer has even allowed regular customers to take home a $12,000 cartridge for audition. I did not try any sort of comparison in my cartridge auditions--the evaluation was more in the line of whether I liked the sound or not. This sort of thing is NOT common, so I sympathize with your "problem."
I know this is somewhat compounding your problem by mentioning another cartridge, but, I would also add the Dynavector XX-2 to the candidate list. A friend bought one and traded in a much more expensive Transfiguration Orpheus. In his particular system, this is a great cartridge.
