【评测图文】SONCOZ SGD1 Audio DAC Review

"This is a review and detailed measurements of the Soncoz SGD1 Audio DAC. It is a new company formed by our member @Ben1987 who had previously designed the super popular Khadas Tone Board DAC! He has left and designed this much higher tier DAC. "

本文是对SONCOZ SGD1音频DAC进行的回顾和详细测量。这是一个由我们的成员@Ben1987成立的新公司，他之前设计了超级流行的Khadas音板DAC！他离开然后设计了这个更高级别的DAC。

外观

这款桌面DAC的设计是独一无二的：

"Lots of inputs and outputs are available:"

提供了大量的输入、输出接口：

"I don't see an external antenna but there is Bluetooth and one of the videos indicates Wifi capability!"

我没有看到外部天线，但有蓝牙，其中一段视频显示有Wifi功能！

"Wow. That is some distortion and noise performance! Highest level distortion product is under -130 dB meaning it is absolutely, positively inaudible. Noise must be low enough to push SINAD up to near 120 dB, placing the SGD1 almost at the top of the charts:"

哇！这是失真和噪音的性能表现！最高水平的产品失真是低于-130分贝，这意味着它绝对肯定听不清。噪音必足够低才能让SINAD到120分贝，

这让SGD1的排名几乎在图表的顶端:

"First up is signal to noise ratio which we can already predict to be excellent:"

首先是信噪比，我们已经可以预测它非常优秀:

"Linearity is nailed as perfect as can be indicating very precise output levels:"

线性度相当完美，可以显示非常精确的输出水平:

"Jitter and noise is as clean as I have seen:"

抖动和噪音就像我看到的一样干净:

结论

"Given the great design skills of Ben, I expected an exceptional DAC and that is almost what we got. There is great attention paid to keeping noise and interference to a minimum. All of this helps SGD1 beat over 200 DACs in SINAD (distortion plus noise)! "

鉴于Ben出色的设计技术，我期待一款出色的DAC而这几乎就是我们得到的。

人们非常重视把噪音和干扰降到最低，而这些参数支持着SGD1在SINAD(失真加噪声)部分击败200多台DAC！

"EDIT: subsequent to this review, the IMD "hump"

was resloved by the designer. He was also gracious to provide the fix for anyone to use!"

编辑:在这次评审之后，设计师解决了IMD的“驼峰”问题。他还慷慨地为大家提供了修复方案!
