Halcro
Bruce Candy, a well-known physicist and inventor was the inspiration behind Halcro. He created an amplifier topology and audio power supply that virtually eliminates distortion. With their first amplifier, which had distortion measured in parts per billion at maximum power, Halcro, which had grown into a subsidiary of Bruce's metal detection company, Minelab Electronics, startled the globe. This firm always uses the best raw materials available to produce its goods.
