In every cable that transports an alternating current, a magnetic field is created. The fields are strongest where the cables are plugged in and where there are any subsequent connections. Using AC Wraps offers a calm stability to the sound, even with cheaper power cords (often unshielded) and cables.
If you are already using more expensive cables, we are delighted to say that no matter the brand it will work better with an Infinity AC Wrap. They do however have other interesting applications! Try them on your speaker cables for example!
Price is per pair.
