重要的事情放前面:因为客服小哥的英文水准不高,极少数翻译不出来的内容已经被删除(角落客服的声音:明明这个歪果仁的语法有问题..-.- 橙色字体是小哥的脑部内容,与原作无关)接下来进入中英字幕的正文:




Pros: Excellent 32/384 DAC performance, Transparency, Detailed, Fully Automatic

优势:出色的32bit/384k 解码表现,透明度,细节体现,高度自动化


Me: I am an amateur musician & avid admirer of music from India. I would like to call myself a music enthusiast, rather than an audiophile. I was inspired by music since childhood, and as the time passed, the passion of music grew in me, and that subsequently led me to join Head-Fi. I usually like to listen to Indian Classical Music along with Bollywood songs. My main listening genres include classical, vocal, instrumental, jazz and sometimes pop. With time, my sonic preferences have very much grown. I avidly admire transparency, accuracy along with neutrality, I mostly listen to full sized open back headphones and my all-time favorite headphones are Sennheiser HD800 & AKG K812, which I run from solid state amplifiers. I prefer & admire transparent solid state headphone amplifiers simply because they provide best possible accuracy, transparency & reliability.

我:来自印度的业余音乐家和音乐狂热分子,不过相对于hifi发烧友我更宁愿称自己是个音乐爱好者。从小就受到音乐的熏陶,随着时间的流逝,我对音乐的热情日益见长,也促使我后来入驻Head-Fi论坛。平时我经常听印度古典乐和宝莱坞的歌曲,听的流派有古典乐,声乐,器乐曲,爵士和一些流行歌曲。时光荏苒,我已经有自己的听音喜好(或者翻译为听音观?),对中性(声音)的透明度和准确性不胜欣赏,大部分时候我听全开放耳机,最喜欢的耳机是固态功放推的深海赛尔的HD800和爱科技的K812。我更喜欢、更欣赏通透的固态耳机放大器,因为他们能推出最准确,最通透,最可靠的声音。

I am an average consumer & a humble enthusiast, I like to pen down my thoughts, & I love to express my feelings. I do not receive for any sort financial benefits through this review. My articles are a purely honest write-up aimed for fellow enthusiasts here at Head-Fi community. My profound thanks to TCG Audio for arranging a sample unit of TRD3+ for my evaluation.

我是一个普通的消费者和爱好者,喜欢写下点滴的思绪和阐述我的感情。在这篇评测中,我并没有收到任何的经济上的好处,文章都是为Head-Fi社区的同道中人写的纯粹而真诚的小文。深深感谢听科技音频安排一套TRD3+的样机给我评测。

Design and Build: The TRD3+ has good overall build quality, nothing to complain about.

设计和工艺:TRD3+整体工艺良好,没有槽点。


The outer case is made up of aluminium, and is painted in matt black. On the front side, we have Volume control knob, headphone jack is present in 6.5mm format along with a power/elect switch. On the rear side, we have USB, Coax & Optical input ports, along with a 2.1mm DC power port .

外壳是铝材料并喷上哑光黑色。正面是音量控制按钮,耳机插口是6.5mm规格,旁边是电源/模式选择开关。背面有USB、同轴、光纤输入口,旁边是2.1mm直流电源端口。


The power/select button alone controls all operations of TRD3+. This device seems to be fully automated/computerized, and it has memory function as well Itelligent input switching, mute relays are also present in the TRD3+. For USB receiving the TRD3+ employs CM6631A for D/A conversion, 32 Bits/384 KHZ capable AKM 4390 Chip. There are no user replaceable/serviceable parts inside the TRD3+. Board is well soldered and has a reliable workmanship. It uses a fixed op-amp for amping which is an Analog Devices AD826. It supports 32 bits 384 KHZ & DSD format. Driver installation is a must, & drivers can be downloaded from TCG Audio’s website. It can also act as standalone DAC when output utilized via RCA outputs sockets. But the power supply is not earthed or grounded & leaks mild shocks when touched.

单一个电源/模式选择开关就控制了TRD3+的所有操作。这个设备似乎高度自动化/电脑化,对输入模式也有记忆功能TRD3+使用了无声的继电器。TRD3+CM6631A作USB接收,进行数模转换,而AKM 4390芯片能解码到32 Bits/384 KHZ。TRD3+内部并没有让用户置换的部分。板子焊接的工艺值得信赖,搭配了Analog DevicesAD826作为固定的运放。TRD3+支持32 Bits/384 KHZ和DSD格式。使用TRD3+必须安装驱动,驱动可以通过听科技音频官网下载。使用RCA输出时,TRD3+可以单独作为解码使用TRD3+电源并没有接地,触碰的时候有轻微的漏电。

I award: 7.5/10 points for build quality & design

外观和设计评分:7.5/10


Sound: The TRD3+ gives out a clinical, detailed & vast space of sensation. Lows are tight, but slightly lack body. Mids sound clear, slightly recessed. Highs are comparatively elevated than rest of the frequencies. Overall, I can call it a very clinical sounding device.

声音:TRD3+的声音是客观的,有丰富的细节和巨大的空间感。低频紧凑,稍微缺乏主干。中频听起来清晰,有一点凹。相对于其它频段,高频听起来相对拔高。整体上看,我能称它为一部非常客观的设备。


Soundstage in TRD3+ is pretty good & has a fully circular 3D imaging. Detail retrieval, and dynamics are excellent are very good for its price tag. Overall the sonic presentation maintains high level of transparency and accuracy. Absolutely zero audible hiss/noise, and zero EMI pickup. But slight ‘pop’ is heard on headphones, when the device is switched on/off. The performance put up by DAC in TRD3+ is worth mentioning, and is just excellent with 32 bits & 384 KHZ & was very resolving & detailed.

TRD3+声场相当不错,给人3D环绕的印象,瞬态和动态相对于价格是非常棒的。总体来说,TRD3+的声音有着高水准的透明度和精确度几乎没有可听闻的底躁,没有电磁电磁干扰。但是在设备驱动和停止的瞬间耳机上能听到轻微的“噗”的声音TRD3+的解码表现值得一提,是非常棒的32 bits & 384 KHZ解码,有着非常棒的分离度和细节表现。

Driving Power: The amping & driving power in TRD3+ is on weaker side, but gives out a loud listening volume.

驱动功率(推力):TRD3+耳放推力相对弱势,但也能推出足够的音量。

Points awarded: 7/10 for sound quality

音质评分:7/10


Conclusion: The TRD3+ is a very well performing USB DAC/Amp combo unit. Overall It performed well . But it has a very clinical presentation, which many audiophiles may not prefer. DAC performance is amazingly good, and has 32 bit and 384 KHZ support, which very few of the DAC's in this price range.

总结:TRD3+是部非常好USB解码耳放一体机。纵然它整体的表现很好,声音的呈现却是非常客观的,而这可能不太合很多烧友的胃口。解码的表现好到令人惊叹,支持32 bit 384 KHZ音源也是这个价位的解码罕见至极的。


Pros: The sonic presentation on this little unit is very detailed, transparent & expansive. Sonically, performs well. But has slightly recessed mids & emphasised upper highs.

优势:这套小机器呈现出的声音信息量十足、透明度和大声场。整体声音表现值得肯定,不过中频稍微有一点点凹,极高频有点亮

Cons: Channel Imbalance, power supply is not earthed, & sound presentation is not likable by all.

不足:偏音(机械电位器小音量会有偏音现象),电源没有接地,声音表现可能众口难调。
