1/2" mount cartridge with MicroLine® shaped diamond tip for the most accurate tracking, separation and performance. This is a superb sounding true audiophile cartridge at a great value. If you want the absolute most out of your records, we confidently recommend the AT440MLb without reservation. The specs do not do this cartridge justice. It should play and decode the vast majority of quadraphonic records (with compatible HiFi system). It will lift the maximum amount of audio information out of the grooves to send into your computer for further processing to your taste. Several audiophile forums we found testified that this cartridge, still made in Japan, not China, will not disappoint!Comes with mounting hardware, brush, screwdriver & hi-end OCC headshell wires for connecting cartridge to your headshell.Note that the cartridge arrives mounted to the headshell aligned well but not custom precision-aligned to your specific turntable which can only be done on your particular turntable. This means that in most cases it will work out of the box but the more discerning ear will likely want to do some additional alignment.
