Infrastructure

Mains setup

Sercal 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.
