刚刚看到，详细的就不搬了，结果如下，

Conclusions
It is clear Gustard has aimed high to build a top-end headphone amplifier. （gustard 想做个高大上的产品））But there are some serious misses. （失败了）One is the low max gain and gain settings that are so close to each other as to not be useful（gain 设置不合理）. Unbalanced/1/4 inch output is an afterthought with performance that is quite subpar subjectively. （单端太次了）Objectively it was good with Sennheiser HD-650 but not with my low impedance Hifiman HE-400i.（高阻耳机还可以，低阻的就算了） Overall, I would not buy this unit for unbalanced headphone listening.（单端呵呵）

Even with balanced output, I am struggling to find a reason to buy the H20. （平衡口也不出众）The massdrop THX AAA 789 has proper gain settings, and far better unbalanced output. （跟789比比？单端和 gain 都好得多）Yes, availability is an issue with massdrop THX so another excellent option is the JDS Labs Atom. （789买不着还可以买 atom）It sounds so good and has so much power that you don't need to mess with balanced cables and such. And it only costs USD $99.（单端二房，atom 性价比爆棚）

Really, the JDS Labs Atom and Massdrop THX AAA 789 have changed the landscape so much that products like Gustard H20 don't stand a chance anymore. Yes, it is a heavier box than both of those combined but I can't see a reason to spend so much more money and get less. So sadly I can't recommend the H20.（atom 和789改变了游戏规则，像 H20这种看起来高大上的以后没有生存空间，我不买也不推荐）


另外，还测试了换运放，结论是测不出来差别，除非用温度计。。。


现在看测试好的都是运放加 buf，有大量负反馈的结构的耳放，传统的无论是 A，AB 还是胆机，测试都基本凉凉。。。期待 ASR 能测个 Pass 的耳放或者功放看看


还是那句话，测试参考参考，最终还是要听，789跑分 nb 不假，听感还不如我这个几十块买的 archel pro

测试结果特别好的一般都是中性无染的吧，音染应该也算是一种失真吧
