A simple power supply noise filter that is inserted in parallel into a circuit. It is said to be effective against noise flowing back from power amplifiers and digital devices. The higher the number, the more effective it is, and the more effective it is when attached to something other than an audio room. The appearance is good with little feeling of use (Kobayashi Hitoshi)
