Koetsu Coralstone Platinum Phono Cartridge
Product Review:
The outrageously expensive Coralstone Platinum Mono has a platinum magnet system, silver-plated copper wiring, and a proprietary stylus shape. It combined "sensational" image specificity and three-dimensionality, even in mono, with "an uncanny physicality and weight" across the entire frequency spectrum. MF: "There's no excuse for the price, except the sound. So get over it."
