我在网上找到这么一个东东,下面是具体的描述,请教各位大虾的是:一、是否真的有效，二、原理是什么？多谢了！
hifi音响系统增强CD！
Ayre Acoustics
Irrational, But Efficacious! （不可理喻的，但灵验的！）
－System Enhancement Disc
This disc is designed to enhance the listening enjoyment of your audio system.
The main tool is a five minute glide tone, that when played through your system at a moderately low listening volume, will improve its sound. While we don't have conclusive proof of the mechanism involved, we suspect that it functions by demagnetizing residual fields that build up in your components over time. We recommend playing this track on a periodic basis, from perhaps once a week to once a month. This track is at the end of the disc so that it can be easily played even if the system is unattended. The other tracks have more specialized functions.
The tracks on this disc were created digitally with 88.2 kHz, 32-bit resolution. Enhanced resolution transfer to the 44.1 kHz, 16-bit CD format was performed using 0.5 bits of dither with a triangular probability distribution function for maximum fidelity.

它，不是音乐，没有悦耳动听的旋律，只有噪音。这是一剂灵丹妙药，你的音响系统用过它，马上给你带来惊喜！带来的是全频细节的提升，低频干净，有弹性。它更是一剂毒药，你用过它就会爱不释手。
几种噪声的测试碟见得多了，但还没哪张能够有这样神奇的功效。
ayre的网页推荐周期性使用这张CD，每周或每月一次。
警告：低频欠缺的小箱子慎用！因为它很可能把低频收紧了导致你更加听不到低频了，嘿嘿。。。。。。使用时音量不宜过大！
还有，这张东东播放时居然也能够找到准确的信息。
