突发奇想:按照高档器材中线材能让声音变化明显的论点,建议生产高档器材的商家提供一个线材声音特性推荐书 ...
下面这个帖子反映的现象一点都不夸张,
90% 的发烧坛的线材广告只会更谦虚。
换线如换肉, 换线如换耳, 换线如换脑: 换线如换机已经OUT了
by: YTG
Hi-Fi 线材是整个系统里面最重要的, 没有Hi-Fi 线材各个模块根本连不起来。
换线如换机一点都不夸张, 俺近来还有了新体会。
1. 换线如换肉
前一排刚好买到一包很糙的米。想起这里的 Hi-Fi 电源线,然后就换了一根单晶的Hi-Fi 电源线试看看。结果很明显饭好吃了很多。
再煮其他很熟悉的菜,结论,很美味。单晶线材确实有用啊。
兴奋得受不了!
后来突发奇想, 用蒸馏水煲了一锅汤, 没放一点肉, 可是仍然有浓烈的肉香。
某 GAMMA 的系列有马肉味道; 某 DELTA 的系列有德国香肠味道; 某 EPSILON 的系列有蛇肉味道 。。。。
总而言之,有了单晶电源线, 用蒸馏水煲汤, 没放肉仍然有浓烈的肉香。
换线如换肉, 超值到极点。
更神奇的是, 煲透了以后, 虾的味道也出来了, 蛋的味道也出来了。
这时候, 点着香炉, 扯一扯撸一撸电源线, 佛跳墙的味道也出来了。
2. 至于信号线, 那是换线如换耳。
普通人换 RCA 线有一耳朵变化, 俺觉得实在是低估了!!!!!
俺觉得至少有 十几个耳朵的区别。
3. 换 USB 线, 那可以说换线如换脑。
自从换了Hi-Fi 发烧 USB 线, 俺周围的人 IQ 从 100 飞涨到 180.
i386 的电脑不用浮点处理器解压也比 i7 快, 还不用 CPU 风扇.
你说值不值?
