當然都可以導電啦. 不好是與純銅來比. Brass通常只有銅的28%! 嚇一跳吧. 你線用的再好, 端子卻是bottleneck!
純銅, 銀都偏軟, 無法直接做端子, 要加工性, 只好用合金. 所以這個是音響的dark side of moon.
我查過Cardas的規格, RCA通通都是用brass, 只有喇叭端子會用銅. 只是不曉得Cardas所謂的eutectic brass是落在怎樣的範圍
聽說真正用copper等級來做RCA頭的沒幾家...Eichmann是其中一家.
我意識到這個問題, 其實也呼應我之前在喇叭, 電源端子的試驗結果.
The cables you now use are made from high-conductive, annealed copper or silver wires - terminated with low-conductive, gold-plated brass RCA plugs.
Annealed copper has a conductivity rating of at least 100% IACS (International Annealed Copper Standard). Brass has a conductivity rating of 28% IACS.
Because of this low conductivity, we believe brass RCA plugs act as a bottleneck to electron flow. Brass plugs may also cause phase errors and smearing through mass and skin effect.
