结果自己看吧，

结论，
Conclusions
We are spoiled at ASR with discovery of good number of high-performing dacs and headphone amplifiers. Given the cost of Yulong D10, I expected it to match or beat those reference devices. That did not happen. A persistent high noise floor (measured, but likely not audible) persisted throughout the measurements. Power output with 1/4 inch jack at 300 ohm was also a bit disappointing.

On the positive front, if you use balanced output, you should be able to drive any headphone to very high levels of fidelity. Most of our reference level DACs lack headphone amplifiers and that is integrated here in the D10. In addition, it is good to see regulatory certifications on the D10.

Overall, the Yulong D10 leaves me just a bit cold so I can't fully recommend it. It is up to you to decide if its feature set, availability, etc. makes it better than other recommended products.

单纯比参数，国产设备一般都不差

这个纯技术测试很不错，有一定参考性。
另一个方面oppo 205之前长期占据榜首，也说明了参数和声音之间并不是绝对统一的。

I suppose this makes it the best measuring AK4497 device reviewed here so far

since it seems rather hard to get the most out of this chip I would say good job Yulong.

That j-test reminds a lot of the better ESS chips with proper ASRC! And funny how spoiled we are by good performers, that this Yulong falls into "very good but not state of the art" category.

BTW, the PCB on this thing looks pretty cool:

我看到楼下的回复是很专业的，指标上9038始终是优于4497的，听感上不是那么一回事，但是4497里面我们是做到了最好的级别！
另外耳放测试甲类分立耳放在很多方面也比不过集成耳放的纯参数对比，有时候为了追求乐感不得不放弃一些参数上的性能。
如果单纯讲参数，我们的金丝雀都可以比DA10的指标更好。早期的Da8也做到一个极高参数水准，但是最近几年我们放弃ESS的方案，重点投入在性能更差的AKM方案上面，是因为它有更好听的声音表现！

建议以后做个钰虎系列，专门刷参数，参数党专用机型

乐感是最重要的

出个刷参数的机器，跟dac3差不多最好，500美元以内我肯定会买

评价一般

作者: sony_duchao 时间: 2019-3-25 00:19
评价好差啊，“同价位不推荐”

这种已经非常优秀的noise floor就因为不是state of the art被挑个毛病，ASR也真是瞎追求高指标。

哪怕比参数，DA10得分也跟DAC3差不多的...4497做到这个指标很不错了；阿米尔不推荐是因为价格比较贵，美 ...

IMD失真比DX3要差一点。其他的是相当不错了。
不推荐一个是价格高，一个是有一些问题，
We are spoiled at ASR with discovery of good number of high-performing dacs and headphone amplifiers. Given the cost of Yulong D10, I expected it to match or beat those reference devices. That did not happen. （并没干掉其他推荐的NB机器）A persistent high noise floor (measured, but likely not audible) persisted throughout the measurements.（底噪较大，能不能听到不清楚）ower output with 1/4 inch jack at 300 ohm was also a bit disappointing. （单端输出基本别考虑了）

DA10的平衡口很不错啊

作者: pseudo 时间: 2019-3-25 09:14
对的，平衡口不错，

On the positive front, if you use balanced output, you should be able to drive any headphone to very high levels of fidelity. （平衡口功率很足） Most of our reference level DACs lack headphone amplifiers and that is integrated here in the D10. （NB DAC的耳放都不咋地，DA10耳放的平衡口不错） In addition, it is good to see regulatory certifications on the D10. (有认证，CE??)

国外很多评测都是用客观参数评价的啊，还有一个评测耳机的网站是客观参数和主观听感结合评测的。国内在这方面还差很多啊，基本都是主管听感，毒文满天飞，先不说是否存在营销的问题，认真评测的不同人可能都有不同的看法。希望有一天也能有客观数据的评测。或许目前阶段客观数据无法完全描述音质的好坏，特别是调音和听感，但我相信，一定有一天，音质、音色可以用数据量化表示。现阶段来说，数据可以表示音质好坏，无法表现调音（猜测）

可惜没有测试S/PDIF输入时的jitter，usb输入使用的是本地时钟jitter固然是低，没法考量pll实力
