FWIW your problem with vocal sibilance may not be a cartridge issue. Clean reproduction requires pristine electronics too. Especially the power supplies.
I've owned both a Shelter 901 and 9000. An elliptical stylus has more trouble tracing vocal sibilance accurately than more radical geometries. I'm currently using a Soundsmith Sussurro. Peter's prototype actually, and it hands down beats the pants off the Shelters.
