The Taiwanese company Keces Audio, which has been fighting for the purity of the power supply of audio equipment since 2002, has introduced a new series of Ultimate stabilisers, which includes their QRP-1500 model. They uses quantum resonance technology, or QRT, in its products, which is also used by reputable manufacturers such as Nordost. KECES stabilisers are based on high-power toroidal power transformers with isolated output windings for each consumer. In the design of the components, power sockets of Keces' own production are used. Features Back to the roots
