The 400.V3 is the 500.V3"s younger sibling with attitude. The 400.V3 is a 2-coil spherical cartridge with enough punch to ensure that any vinyl that passes under it, gets a loud boomy output. With a combination of the ruggedness and value of the 500.V3, and being the worlds loudest cartridge, the 400.V3 packs more bang (or should we say boom) for the buck than any other needle in the world. Available in a single version only
