This report was generated by RightMark Audio Analyzer 5.5 测试小节： 该规格的测试可以从较为客观的方面反映出声卡的性能，我们认为它实际上可以用来考验产品标注规格的真实性。从测试成绩看，该卡在这部分的测试成绩相当理想，所有成绩的总评定都是“Excellent”！频响曲线几乎成了一条直线，因为采样率达到96kHz后，采样率在高频部分的限制得到了较大改善，测试成绩比较客观的反映了声卡在这个项目上的性能。在更重要的互调失真的测试三个子项中，声卡的表现依然抢眼，最差的成绩也仅为0.0002％！可以说这款声卡的硬件品质是相当不错的。不过很可惜，这只是该声卡的最高采样规格下的成绩，因此，在大多数的情况下，我们无法领略到该声卡的优秀之处。或许只有在DVD-Audio或者SACD正式普及后我们才能有福消受。
