This is a power cable from MIT, a well-known company for audio cables. It was used for audio equipment. I enjoyed the change in sound, especially in the low frequencies. It has a structure that eliminates interference caused by capacitive dielectric distortion, using low-resistance silver-clad special conductors and ultra-low dielectric insulators. It seems that the materials were developed for the higher-end models with boxes. Since there is no box in the middle of the cable, it might be easier to find a place to install it than the higher-end Oracle models. It was moderately available in Japan, but recently, it's become less common. I think it will be even harder to obtain in the future. I only have this one. It's a shame, but I'm letting it go to reduce my belongings. How about taking this opportunity? It was used in a smoke-free and pet-free environment. It was wrapped and stored in a humidity-controlled room, but since it's a vintage item, it might have a slightly dusty smell.
