Dear @richardkrebs : Good that you have a new cartridge that fulfill your priorities.
Those priorities are mainly the ones that bias each one of us preferences to say: " this is the best cartridge I heard ".
SS manufacturer is very good for marketing and in my opinion what you are listening has a direct relationship with the new cartridge body design that promotes lower internal resonances/vibrations/distortions but that that " fact " could be says that the cartridge stylus it's more time in contact with each groove I think it's not true till the manufacturer can prove it.
Cartridge body shape is an important issue for any cartridge, we can see that importance not only with your cartridge but other cartridges as the A95, the Verissimo and others. The Colibri avoid that issue just several years ago with it's body-less design.
"" it tracks superbly . " again that's your bias because the cartridge compliance is 10cu that's almost " marginally " for grooves tracking.
As you and other side it's an almost impossible question to answer, there are to many paramerts involved in each cartridge that contributes to its quality performance and additional are our priorities.
Btw, " Front runners at the moment are Grado and DaVa...""
in good shape @terry9 , that Dava FR is around 6db out of a " decent " cartridge FR. The Hyperion is only 2db. Obviously that you have your own priorities and thta's what I'm saying.
