(Means for Solving the Problems) In order to solve the above-mentioned problems, the inventor of the present invention has conducted extensive research and experiments, and has found that conventionally known precision resistors are designed to reduce the induction generated when current is applied in order to function as pure ohmic resistors. It is a so-called non-inductive type, in which resistance wires or thin resistance films are arranged so that the magnetic fields cancel each other out, and it is said to have excellent electrical characteristics even when dealing with signals on the order of gigahertz. However, it is theoretically predicted that resistors for audio equipment that handle signals in the audible frequency range may be arranged inductively as a so-called inductive type so that the induced magnetic field is not canceled when current is passed through a resistance wire or thin resistive film. It has been confirmed that the deterioration of electrical characteristics is not a problem at all, and in fact, a dramatic improvement in reproduced sound quality has been empirically confirmed, which is contrary to common sense.

(Function) Although it can be audibly confirmed that the above configuration of the present invention achieves a remarkable improvement in the reproduced sound quality, the mechanism thereof remains to be theoretically elucidated in the future. However, in order to improve the playback quality, we focused on the purity and crystal structure of the resistor material, and the resistor material was designed in a way that minimized distortion to the signal current.
In other words, it is considered that the arrangement in the forward direction so as to form an induced arrangement contributes synergistically.
