到了测试环节了，相信广大读者也迫不及待了。不过还是要先介绍下测试平台。测试主板为华硕P5K-E
PLUS，电源海韵650W，测试声卡采用了回录测试，也就是自己出声自己录制的方法。小熊在线www.beareyes.com.cn
而测试时采用的音频信号线也是比较豪华的，由pailiccs公司生产，线材本身非常的租，而且线的表皮采用防干扰编织，编织的非常精细，抗干扰能力要比普通的塑料皮线强很多。接头采用了18K镀金，保证传输更好的音频信号。小熊在线www.beareyes.com.cn
只有半米的音频线价格却有百元
测试平台简单介绍到这里，我们一起来看看RMAA的测试结果，RMAA选择了目前的最新版本-RMAA6.0.6
