回复 173# Lighting 的帖子
你说的这股空穴来风都是洋人搞起来的,跟中国人一点关系都没有, 参考这里:
http://www.normankoren.com/Audio ... 2.html#HarmonicDistIn the 1950s and early 1960s, high fidelity tube amplifiers had 0.5 to 1.5% THD at rated power output. In the 1970s, a distortion race took place that paralleled the automotive horsepower race of the 1950s: If 1% THD was OK, 0.1% was better, and 0.001% would be really awesome. The more leading zeros, the merrier. These low THD levels were primarily accomplished by increasing negative feedback to levels well beyond 40dB. We all know the results: amplifiers that sounded so bad that— a real silver lining on a dark cloud — they gave birth to the high-end audio industry we know today.
现在那些所谓的专业监听就是现成的例子,都号称失真很小,最精确保真,说实话,都很很难听。
听感是器材和人耳/大脑的互动过程,你不研究耳朵和大脑,光去研究器材那一个方面,你觉得这很”科学“? 仪器是可以比人脑精确,就像电脑比人脑精确一样,但是,电脑只会简单的计算,不会复杂的推理,仪器可以测量某一方面的数据,但是对一个复杂的过程来说,有一台仪器可以测量所有影响听感的因素吗? 如果听感都可以用仪器测出来,那事情就简单了,把仪器测的各种指标列出来,跟听感一一对应,明码实价,我们买器材也不用去听了,你也不用去什么音响展了,看看指标,就知道是什么声音,生活多美好啊。
我不是说听感和失真没有关系,我的意思是,失真低到一定程度,对听感的影响就没有那么大的关联了!
