Stereophile的读者调查：在发烧友家中，到底有没有可能有完美的声音重播？
结果57%认为永远没可能。

其中一位讲到：
You can't measure something like sound without altering it. The inertia of the microphone's diaphraghm inertia distorts the sound pressure front terribly. Then there's the recording technology, amplification, and those really big distortion sources: the loudspeakers. It's best to just enjoy the music-like sound that does make it to your ears.
大意是：话筒振膜的惰性对声压造成极大的破坏。。。。。。。
不要叫我翻其他的啦 ：）
不错我们离完美还很远，乐观的讲我们的发展空间还很大，个人认为特别是在数码领域。
