The Goldring 2000 series use Moving Iron (output the same level as a Moving Magnet) with affords the benefits in performance found with Moving Coil cartridges but with the
same output level and the advantage of a replaceable stylus.
Moving Iron afford the use of a dual system a Samarium Cobolt magnet and a high output coil are combined to bring the audible benefits of moving coil cartridges (which are usually priced from £300 upwards) and the advantage of the replaceable stylus which is a hallmark of a moving magnet cartridge.
The output of the Goldring 2000 series of moving Iron cartridges are inline with moving magnet cartridges. This means so long as you have a phono amplifier (either in your amplifier or separately or even built into your turntable) you can replace your existing Moving Magnet cartridge with no additional requirements.
The sonic improvements are clear to hear, the groove is very accurately tracked allowing for wonderful detail and dynamics.
