Non-Magnetic Connections

Non-magnetic connections minimize micro-microphone modulations in the current path. In a power supply capacitor, the current flows not only through the coil, but also through the connecting wires and contact points — and this is exactly where ferromagnetic materials can produce undesired effects. Non-magnetic connection materials avoid magnetization and hysteresis in the conductor and thus reduce current-synchronous, very fine impedance modulations. This is a micro-microphonic measure in the actual power path: The connection is closer to the ideal conductor, without “magnetic interference.” In addition, there is additional electrotechnical benefit because non-magnetic, highly conductive materials often lower and stabilize contact and transition resistances. As a result, energy is available more evenly at the amplifier stage — and the sound remains quieter and more controlled.

Tonal effects

• quieter background and less “grit” with complex music
• more stable transients because the current path is less finely modulated
• clearer contours and cleaner room images at high levels
• more consistent sound quality due to more stable contact and conduction conditions

Manganin Alloy

Manganin is a copper-based resistance alloy with a defined content of manganese and nickel. It is characterized by a very low temperature coefficient (TCR), high long-term stability and mechanically “softer” behavior in metal lattices. This results in lower conductance fluctuations and reduced micro-microphonic effects compared to harder oxidic layer systems.

Copper-Nickel alloy

Copper-nickel alloys (CuNi) are resistance materials with a defined nickel content in copper. They are characterized by stable electrical properties, good temperature resistance and controlled mechanical behavior in metal grids. Compared to metal-oxide layer systems, they react less rigidly and are therefore less prone to micro-microphonic resonances.

Tight Tolerances

Tight tolerances in capacitance, inductance, and resistance ensure that capacitors of one type are very close together in terms of their electrical properties. In crossovers, the left and right channels therefore work virtually identically: crossover frequencies, level ratios and phase positions match closely. This is the basis for stable, precise stereo imaging and reproducible results — in series production and also after service.

Tonal Effects

• precise, stable soundstage without drifting
• Coherent overall impression: left and right channels fuse into a single, seamless whole
• characteristic sound is reliably retained even after component replacement/repair
• More stable virtual center and clearer spatial layering
