All Goldring 2000 series cartridges feature Moving Iron technology. This lends them the high levels of detail associated with more expensive moving coil designs whilst retaining the convenience of a replaceable stylus and high output associated with moving magnet types.
The cartridge employs a fixed samarium cobolt magnet and high output coil combination so that a very light iron/nickel cantilever end-piece can be used instead of the much heavier permanent magnet used in conventional designs. This reduces the moving mass allowing the stylus to trace the record groove more faithfully.
Because of their high output, Goldring 2000 series cartridges should be used with the standard moving magnet phono input of an integrated amplifier.
The 2500 has a tapered cantilever with 2 SD diamond giving it a smooth but detailed sound, while the metal body delivers fine bass definition.
