A special construction made from natural felt keeps the live from both neutral and earth conductors at a defined and steady distance. Conductors are the highly regarded, multiple award winning noise-cancelling Lessloss cables, consisting of 288 individually insulated strands with a total conductive cross sectional area of 3.5 mm² per polarity.
For the live and neutral conductors used in our M3, we asked Lessloss to develop for us the perfected version of their already outstanding achievement, resulting in a performance that betters even the M2 by much. This is achieved by a different weaving geometry, now all conductors being in one and the same layer with equal distance to the center, allowing a near perfect 90° overlapping angle of the individual coils for near perfect noise cancellation:
C-MARC™ is a new type of Litz wire. C-MARC’s™ noise reduction is based on the bucking coil method using two counter-polarized coils. Every strand’s clock-wise turn aligns with a corresponding counter-clockwise turn of exactly mirrored diameter and step. The two resulting counter-polarized coils are mutually superposed. A second-scale fractal replication of the already bucking coils is then repeated. Through electrical cancellation of the induced noise, C-MARC™ provides an enormous signal-to-noise ratio in today’s demanding environment.
The perfect marriage between conductors and the massive high-purity copper pins is not screwed, but a perfect solder connection.
Why is that worth mentioning?
Because plug or screw contacts even between apparently mirror-polished surfaces aren’t what they seem. Just view them under a microscope. They’re anything but smooth. The contact surface between plug and receptacle is actually pitted to raise the impedance and be prone to micro arcing. With power transmission, such contact resistance is even more detrimental to performance than it is for signal transmission. That’s because power transmission can demand high peak currents that must be delivered instantaneously. Wherever stranded Litz wires terminate screwed down inside a power plug, inevitable oxidation over time renders them subject to sonic degradation and safety concerns. Copper oxide has semiconductor properties. Those properties act as a radio-frequency receiver. Soldering all our connections with 10% Audio Consulting silver solder fixes these problems for good and generates a leap up in sound quality over power cables with screw contacts, where each and every such contact add up in the negative sense.
