AK-2000/50 Speaker Cable - Discontinued 3.5m x 2, 7m - 450 yen/m, Total 3150 yen (at the time) The Denon AK-2000/50 audio cable uses high-purity OFC (Oxygen-Free Copper) wire and a composite structure of three wire diameters optimized for low to high frequencies. The parallel wiring design suppresses signal degradation, especially over long distances, and achieves faithful audio transmission. These cables have been kept since I bought them about 20 years ago.
