Eliminate noise right at the source. Our Noise Harvester is a parallel noise elimination device. Plug it into any AC outlet and it collects line noise and converts it to harmless light. Similar plug-in noise reduction devices simply place a capacitor across the AC line which only shunts line noise from hot to neutral but does not eliminate it. Only a Noise Harvester collects and stores the noise in a capacitor and when enough energy is available, discharges all the unwanted noise into light and it’s gone forever.
Most power conditioners attempt to isolate your equipment from all the power line noise, but they cannot eliminate or remove power line noise. Only the Noise Harvester removes AC noise and converts it to another form of energy, light. Give your power conditioner a nice head start by lowering your noise floor in the first place.
The QED speaker cable story began in 1973, with the launch of the world’s first specialist speaker cables, QED 42 and 79 strand, now household names in the audio industry. Building on this longstanding British speaker cable heritage, QED embarked on an exhaustive research program into cable parameters which began in 1995 and continues into 2017 with the release of “The Sound of Science”, a 40 page White Paper distilling the research published since 1973 by QED.
