应该算是小改版吧
似乎是把类比的部分强化了

"Now in Analog 2 form (shipping since late 2017), we’ve combined the output
of four of these DACs with DC-coupled, low-noise, Class A JFET buffers and
summers with high current output capability to drive long cable runs and
low-impedance line inputs, such as 600 ohm professional gear."
以上看不太懂XD
总之2017年底出货的世界树已经是二代类比电路
原有的也可以升级 http://www.schiit.com/products/yggdrasil-analog-2
在Computer audiophile上也有发布
