Picture of RCA-X cables

As a result of our researches on the wire line transmission of low frequencies AC signals, the LEFSON RCA-X line of analog interconnect cables is composed of five models : RCA-X1 to RCA-X5.

Designed for audiophile people and professionals of sound, the LEFSON RCA-X modulation cables reveal the true potential of the devices they are connected to.

The five models of the range allow everybody to benefit of our fundamental researches, and are corresponding to the value of any HI-FI or professional system. All LEFSON RCA-X cables are very flexible, protecting from any undesirable vibration phenomenon. They are also shielded, which makes them usable even for a high-impedance link or near sources of electromagnetic radiation (power supply transformer, mains cable, speaker cable, etc...)

RESISTOR & RESISTOR-D

- PREMIUM / SUPRA / ULTRA -
Audio Precision Carbon Resistor

Picture RESISTOR


The audio resistors LEFSON RESISTOR and LEFSON RESISTOR-D (dual) are very high performance pure silver / carbon audio resistors. They are made of a pure graphite resistive element and pure silver leads. Suitable for speaker crossover or Emitter/Source resistor of transistors in preamplifier/amplifier, the LEFSON RESISTOR and LEFSON RESISTOR-D are pushing up the limits of sound reproduction.

The different lines PREMIUM, SUPRA and ULTRA allow the user to choose the level of required performance. Near zero inductance and distortion, heat sinkable, mechanical earthing possibility, incredible neutrality, the LEFSON RESISTOR and LEFSON RESISTOR-D are the ultimate solution to improve any analog circuitry.

As all other products of the LEFSON trademark, hand assembly and electric tests are made in our workshop in Northern France.
