Measurements of YinLuMei P2 USB DAC/HPAmp

前阵子测了音律美的M400之后,就又有玩家联系我,说能不能寄一个 YinLuMei P2 给我测。我简单了解了一下这台机器,实话说有点惊叹于配置(双AK4497!)而且属于一种很特别的“Mini台机”的玩法……那么就等着到货测量咯~

怎么说呢,由于没有查到当年的价格,就按照现在1K6的二手价来算,双4497本身还是很值的,虽然是磨标的运放,但运放加上疑似LM49600的耳放架构有点类似于刚测过的ATOM,只考虑耳放来说应该问题不大。不过从电路的布置来看……似乎有点点奇怪?因为负责音量的PGA2311芯片的位置和DAC、耳放之间的位置关系总感觉不那么顺畅。无所谓了,开始测量:

怎么说呢……现在4497价格高,拆了比较好
