Measurements of SMSL D400EX Dual 4499EX DAC

前阵子测了本站的第一个AKM4499EX解码,在3K多的价位还是近乎首发的情况下,那台设备的表现中规中矩。当时我就在想,三小强(Gustard、SMSL、Topping)在干嘛呢……这芯片发布那么久了还没拿出机器……结果我很快就收到了来自SMSL的4499EX机器!这台还是双4499EX!

外观其实……中规中矩把 不算好看的那种。做工拿在手上感觉挺瓷实的。但那个旋钮我很不喜欢。废话不说,开始测量:

总结:单端虽然仅仅是压线,但毕竟SINAD120了。总体来说还行,但总觉得大家对于4499EX芯片使用的成熟度还不够高……

  1. 高频的毛毛有点多啊,虽然强度都很低,这个算不上是问题,没准反而还有利于“调音”。
    但是互调看起来是真不太行,这里再优化一下就很好了

  2. D400EX有个Sound Color的设定,可以把AK4499EX的取样率提升到11.2896MHz (默认是5.6448MHz, SOUND 1 ),声音确有提升,可能测能分数會有所提升。

  3. 我觉得还行哦,现在解码性能都这样了,实际在系统中对声音影响最小的就是解码器了吧。我换过多款解码器,我既然听不出声音有什么区别,远不如换音箱、换功放来的直接。

  4. Where is your “sound color” 5.6mhz and 11.28 mhz test? 🙂 🙂 🙂
    Without this, the test is not complete.
    Also, your test will not coincide with the AMIR test, where the linearity is even and unlike yours, where there are attenuations at the edges.
