Measurements of iBasso DC06 USB DAC/HPAmp

iBasso的小尾巴是本站的老朋友了,从DC03DC04DC05。这两天又有好事者给我寄了新出的 iBasso DC06 ,说是它家又发布了新的小尾巴……让我看看这次有没有什么新瓜可以吃(DC03 04 05的完成度都有点不尽如人意……)

铝合金的壳子比较精致,具体的我们看测量:

满幅输出的SINAD不甚理想,那么是不是虚标了呢?真不是:

看上去还行,但是50mV为什么那么低?因为低输入或者无输入的时候有奇怪的底噪:

但输入电平到一定值之后(好像是-120左右dbFS)就没有了……问题不大


总结:这次完成度好了一些,但是依然……不算特别好
