俺昨天作了点功课
首先是“快”,俺找到一个很有说服力的说法
You could almost say a Klipsch is the inverse of Quad ELS design philosophy; instead of optimizing for minimum energy storage with low mass drivers and no cabinet signature, the Klipsch is optimized for very low IM distortion and extremely wide dynamics. What's really interesting is that both sound open and fast - but technically, they do so for completely different reasons.
This is why most audiophiles don't know what they're talking about when they discuss "good transient response". Without measuring, you have no way of knowing if it's low IM distortion, lack of voice-coil heating, more headroom before overload, absence of cabinet resonance, or fast settling time. All of these subjectively sound like "good transient response".
//Good transient response应该是相当的接近“快”了。
//Denon的不好啊。1K处有明显的能量堆积(单元染色、箱体共振或者别的原因),很严重啊。
//CSD测量的条件很严格,它的原理是在单元的发声还未被反射的情况下进行快速的数据分析,进而可以模拟昂贵的无回声室的声音特征。它的主要作用是寻找narrow-band resonance,所以对于耳机来说,12ms的测试时间有些不合理。
//CSD理论上是静电的长项,也就是非常低的能量堆积或者是更好的瞬态,或者说是非常快的impulse response。
但是昨天takase兄贴出的head-fi里有一些很糟糕的静电CSD,我很疑惑,所以去翻了Stereophile的测试,他们也很疑惑——照说Quad静电的impulse response很漂亮,——除了一个很奇怪的干扰,编辑认为是静电的那个罩子的回音。
