Meet "El Supremo"- Introductory pricing on the new Higher-End black ceramic fuses from HiFi-Tuning Germany.
HiFi-Tuning of Berlin-Germany has released a new highest performing version of their industry-leading fuses called "Supreme".
The new line of Supreme fuses is handmade, tip-to-tip of 99% Silver combined with 1% 24k Gold, similar to the material used in the Mundorf Supreme Silver/Gold Capacitors.
Mundorf also developed for HiFi-Tuning a special Silver/Gold solder for use in the Supreme fuses.
HiFi-Tuning's 99% Silver + 1% Gold melt wire, used exclusively in the Supreme fuses, is resonance-optimized to control vibration.
Technical: To understand the advantage of the 99% Silver + 1% Gold combination, think about silver's crystalline structure. The drawing process for silver (or copper) wire causes micro cracks in the surface of the wire. The cooling process also results in imperfect crystal grid structures. Both of these "deformities," relative to the ideal of a perfect conductor, result in surface distortion when current flows through the wire. The addition of 24K gold fills the micro cracks and the empty spaces between the crystal boundaries to improve transmission properties, while also inhibiting the surface oxidation and tarnishing that will occur over time otherwise.
These custom, precious metal fuses are also cryogenically treated using Europe's only cryo system from Cryogenics International (USA).
Finally, the Supreme fuses are treated with a proprietary quantum level process.
Fast-Blo and Slo-Blo Supreme fuses are available now in most popular values in the usual sizes: 0.75" (5x20mm) & 1.25"(6.3x32mm), and are rated at 250V.
