The cutting machine. Maybe this is common knowledge but I'm new to the forum and I wonder.... How is the cutting machine able to create such quality. For the cartridge we have to pay x thousands of dollars to get everything out of the groove. (well from $50 for a reasonable sounding and maybe $ 5000 for the best) Having almost zero mass for the moving stylus. This must be a lot more difficult for the cutting machine, well it should require a lot more mass to be able to cut in ... (well what do you cut actually?) So is the cutting machine a far more expensive machine than I guess or is there a physical reason that this is less critical then I expect?
