Aroc, I don't know that we disagree a lot. I would not put a shelter 901 or a Lyra Titan on a Dual CS 505, but I also would not put a Sumiko Pearl on a Walker Procenium Turntable.
At the same time the better cartridge will sound better than a lesser cartridge on any given TT. The cartridges ability to retrieve the signal is extremely dependant on the arm and table doing their job correctly. So a better cartridge is always more important to the ultimate signal that arrives at the speakers. I'm not sure if there are any right answers either, since there is a lot more opinion and a lot less fact involved in this hobby.
