"It is unusually thin for a speaker cable. The reason why I made this is that there is a fundamental contradiction between the low conductor resistance and low eddy current loss required for a speaker cable, and it is impossible to satisfy both, so I decided that the best policy would be to ensure low conductor resistance by putting a feedback mechanism in the main amplifier, and to have the cable take care of low eddy current loss. In other words, the idea is to obtain good overall characteristics by having the main amplifier take care of the low range and the cable take care of the high range. Specifically, it is a product called "LB-4" from "Fidelix" that is designed to be used with a main amplifier. If you use it with other products, you will need to take some measures, such as separating the pre-amplifier and main amplifier and placing the main amplifier very close to the speaker to reduce the length of the speaker cable. If you use it well, you can get very high resolution. " (Quoted from the Mogami Electric Wire website)
