Makes sense - the Prestige range are fundamentally good designs let down by Grado using moon rock for the stylus tip.
They don't even give stylus profile in the cartridge specifications. Can you think of any other cartridge manufacturer who does that?? All things considered, I think they are cheapening the products, charging the same money and trading on the past reputation. I imagine you have a bunch of people who can't or don't want to invest time and money in development and are just trying to collect money until retirement ticks round.
