专辑介绍:

   许多乐迷在选购音源CD机或音频解码器时都难免目迷五色，无从下手，那么有没有一盘能不借助于仪器就能试出器材性能的试金石呢？回答是肯定的，由喇叭花唱片推出的《My Disc》又名（我的碟）就是这样应该人手一张的勐碟，它不仅用于挑选音源，还用于整个音响系统的甄别和最后的摆位调校以及煲机和练耳，被誉为发烧友人人必备的利器。

如何使用《我的碟—Sheffield／A2TB测试碟》

       在美国Sheffieldlab公司出品的《我的碟》(My Disc》，the Sheffield／A2TB Test Disc)的封面上，制作人写着：“一张评估音响器材、听音环境及听音能力的测试碟”。的确，这是一张音响发烧友不可缺少的用于进行全面音响测试的工具碟。这张光碟包括音乐测试和技术测试。音乐测试部分选择了几种音乐式样，这样几乎每个人都可找到一种音乐形式来适合个人的口味。技术测试部分录制了各种测试方法及测试信号，这样会排除很多变量对音响系统全面表现所带来的影响。这张测试软件包括了一些特殊信道，使你在使用或者不使用专业测试设备的情况下都能分析音响系统的表现．个别信道只能在使用专业测试设备时使用，这几个信道用一个手形符号标出。即使你有专业测试设备，但你可能并不总是随身携带着，例如当你在一位朋友家评估一套音响系统的时候，或在试音室里试听一套音响的时候。无论你是一个音响发烧友还是一位音响专家，《我的光碟》都将是你最有用的软件。为了说明这张碟的一些效果，制作人不得不在一些音乐信道中演示特殊方法。前六个信道是从原版中直接数码输出。这些信号的用意是既有参考性又有一般性的听音评估。
