This a German made “device” that was designed to remove unwanted electrical noise from your system. In most areas or setup, the electrical current can be “dirty” in the sense that along with its current flow, it brings about noise to your system. Some areas or setup would be dirtier than others but in most cases, they are all not that bad unless you are living off grid or have poor electrical supply. So when there is poor electrical supply, the Noise Destroyer can help eliminate or suppresses it down where it allows more music to come out from your system. In the worst case scenario, the Noise Destroyer does not introduce any negative impact to your system and you will still enjoy what you currently have. But when it does help, you will pat yourself on the back for a well spent audio accessory.You can plug this into one of the outlets in the power conditioner or the wall outlet when you are drawing out current for your hifi system. Unit is rated for 100-240V use so it can be used anywhere in the World.
Cosmetically, the unit looks good with minor scratches/nicks common with use. Unit will be securely packed for safe shipping.
