This is the "Shades Of Blue" RCA cable, made by combining 0.125mm blue silk wire from a 1950s Soviet-era Russian source with 24ga Western Electric single-core wire from the 1960s, using a special recipe. The price is for a pair of 50cm cables. This cable uses a large quantity of rare aerospace-grade military copper wire, USSR-era Russian blue silk wire with dark brown enamel. The characteristics of this material are a wide frequency range, with a low end that is incomparably heavy and rich compared to Western Electric and Belden, and a high-frequency response that is the epitome of delicacy. The expression of silence is amazing, allowing you to feel the reverberation of the instruments. By incorporating Western Electric single-core wire, this RCA cable achieves both punch and sharpness in the mid-range. Shielding is applied for noise resistance. While this cable should suit a wide range of sound sources, it is particularly well-suited for classical music and jazz, and other quieter sound sources. Connectors available are RCA, TS, TSR, and XLR. *The price is for RCA connectors. Other connectors will be quoted. Length can be adjusted in 10cm increments for an additional 1000 yen, so please feel free to inquire. We are confident that customers who have been satisfied with our vintage lead wires and RCA cables will also love this cable. We hope you will try it. Belden is set as the manufacturer for search purposes. Depending on stock availability, the plug cover color may change to black, but this will not affect the sound quality, so we hope you will use it as is.
