Sparkz S3

Ansuz Sparkz S3 is a mains noise-reduction device made by Ansuz, designed to plug into unused mains sockets. It uses third-generation Gold Anti-Aerial Resonance Coil technology with three Gold AARC coils, a zirconium bar, and silver/gold-layered copper coils; the circuitry is housed in Bakelite. The unit measures 39.4 × 71.2 mm (1.55 × 2.80 inches) and undergoes cryogenic treatment at approximately −321°F (−196°C), which the page states increases conductivity by 6–8%.
