Fidelity Audio mains filters used to reject mains born noise and spikes, you hear a more three dimensional and rich sound with a really low noise floor. Good quality mains leads (Russ Andrews Reference cord - with fuses shorted using copper rods) added to lower the mains impedance and reject noise air born noise. The mains block is the Fidelity Audio NEXUS mains block made from oak and fitted with a No Noise Ultra mains filter for added space and dimentiality.
