Sparkos Labs writes: “Here is a view of under the hood of the prototype enclosure. The Toroidal transformer is covered by Giron material, which shields everything in the box from the transformers magnetic fields. That, and a dissipative, lossy bridge rectifier network with softening resistors to reduce peak charging currents into the reservoir capacitors (which in turn reduces transformer magnetic fields) coupled with a Giron divider between the power supply and amplifier sections (not pictured) should render all of the magnetic fields from the transformer completely harmless. Without these precautions, pickup from the transformer’s magnetic fields would both dominate and destroy the noise performance.”
