Dear friends @halcro : As with ruby/saphyre diamond is synthetic too and more a hype than a true reality that cartridge with diamond cantilevers performs best, it's only marketing.
The manufacturers of diamond cantilever cartridges put very special attention/care on each one an all parameters, measures and voicing with their diamond cantilever models to the cartridges can achieve a different ( but not really better ) sound quality than the same models with boron cantilevers but if those same designers put the same grade of care, tigth tolerances, voicing, etc, etc with the boron ones these boron cantilever cartridge will outperforms the diamond one.
For me and till today boron in that specific job is unbeatable.
Regards and enjoy the MUSIC NOT DISTORTIONS,
