Also the sound is perfect,  because high-quality components guarantee an audiophile sound experience at its best. The features are also impressive: Auto Turn-On Function, EPS, variable crossover filters – everything your heart desires is on board. High-quality connectors and screwed RCA sockets complete the perfect appearance.
