Sound :
First, all the usb to spdif converters listed in this review outperformed the usb inputs of the DACs I have on hand. So as long as they are used with a decent spdif cable (such as the affordable 18ft. Belden 1694 digital Cable), there should be sound improvement in many dacs (at least with the ones I tested).
Second, I have noticed big differences between usb cables (Edit -- For those skeptics on why there are differences between usb cables, please read the 23/03/10 follow-up). So I settled for the review on the best one I own (the Wireworld Ultraviolet USB) and used it for all the converters and the DACs except for the m2Tech Hiface. Therefore, it is important to note that the m2tech converter has a slight comparative advantage since it doesn't need the use of a usb cable.
Also, for those who might be interested, I wrote a full length review of the DAC-19mk3 (here) that I used for this review. It should give a good idea of a baseline of the sound in my system. I was using the Musiland back then with the Mode A digital filter for the DAC-19 mk3 and the ST-3 head-amp. Since then I upgraded to DF-1704 digital filter (mode B) and the C2C head-amp which made my system more revealing and transparent.
首先，所有的USB到本次审查上市SPDIF的转换器的DAC的表现优于我手边有USB输入。所以，只要他们拥有体面SPDIF的电缆（如。贝尔登1694年有线数字电视实惠一十八英尺）使用，应该有很多DAC的声音改善（至少是那些我测试）。
第二，我注意到之间的USB电缆（编辑 -关于为什么USB电缆之间存在差异，请阅读那些怀疑者的23/03/10后续行动）的巨大差异。所以我决定进行审查的最好的一个我自己的（紫外线的Wireworld USB）和用于所有的转换器和除m2Tech Hiface它的数模转换器。因此，重要的是要注意到，m2tech转换器有一个轻微的比较优势，因为它并不需要的USB电缆。
此外，对于那些谁可能有兴趣，我写了DAC的-19mk3（在这里），我为这次审查使用全长审查。它应该是一个系统的声音在我的基线好主意。我用的是Musiland模式与当初在DAC的数字为19 MKIII飞机和ST- 3头放大器过滤器。从那时起我已经升级到的DF -1704数字滤波器（模式B）和C2C的头放大器这使我的系统更准确和透明。
EMU 0404 USB :
I had the 0404 usb for a long time, so I was very familiar with its sound from its analog outputs. When used as usb DAC, the EMU 0404 USB is "bright" sounding, lacks deep bass and the overall sound can be described as "edgy". The sad thing is that those attributes also reveal themselves in the digital output which sound edgy and congested in the top and light in the bass in comparison with the other converters I have.
However, compared to the usb inputs of the Audio-gd DAC-19mk3 or the DAC-100, it is a noticeable step up in resolution and bass tightness.
Also, it is very sensitive to the latency settings : setting that latency from 2ms to 4ms can definitely improve the sound of the higher latencies. However, the EMU 0404 becomes more sensitive to anything else running in the computer and it shows trough crackles and pops. This is especially true forFLAC files as even 24/96 wav files can play at the lowest latencies without a glitch.
Note on USB cables :
I first discovered the effect of usb cables while using the EMU 0404 usb with the Audio-GD DAC-100.
I was doing a comparison between the spdif input of the dac-100 and its usb input, and for a few trials I preferred the spdif input using the EMU 0404 as a transport. When I did the same experiment a little bit later, I found that I preferred the sound of theusb input of the DAC-100 over that of EMU 0404 as a transport. The only thing that changed between experiments is that I used a Belkin cable with the DAC-100. I repeated the experiment many times and could detect the differences : the culprit was the stock usb cable that comes with the EMU 0404 that it is the worst sounding of all (it is also poorly constructed with thin conductors and ferrite shielding).
That led me to buying different usb cables from Monster, Real cable, Belkin Gold, and finally Wireworld Ultraviolet. All of them have different sounds but the Wireworld is clearly superior sounding and it also allowed me to reach the lowest latency settings with the EMU 0404usb without suffering from crackling and pops.
我有很长一段时间的0404 USB接口，所以我很其其模拟输出的声音熟悉。当为USB DAC的使用，欧洲货币联盟0404 USB是“光明”测深，缺乏全面深刻的低音和声音可以被视为“前卫”中所述。可悲的是，这些属性也揭示了数字输出自己的声音毛躁，在顶部和与我有另外的转换器，低音比较轻挤塞。
不过，相对于这些影音广东数模转换器- 19mk3或DAC - 100的USB输入，这是一个引人注目的步骤和低音号决议紧张了。
此外，它是非常敏感的延迟设置：设置从2毫秒的延迟4ms的绝对可以改善高延迟的声音。然而，欧洲货币联盟0404变得更加敏感，在别的计算机上运行的，它表明槽裂纹和持久性有机污染物。这是因为即使24/96 wav文件尤其如此forFLAC文件可以播放没有毛刺的最低延迟。
USB电缆的注意事项：
我第一次发现了影响，而使用USB电缆与音频钆数模转换器- 100动车组0404 USB接口。
我在做之间的DAC - 100 SPDIF输入和USB输入的比较，并为少数审判我更倾向于使用SPDIF输入作为交通工具的动车组0404。当我做了同样的实验一点点后，我发现我的首选以上的动车组作为交通0404说，theusb的DAC - 100输入的声音。唯一改变的是，实验之间我所用的DAC - 100贝尔金电缆。我重复多次实验，并且可检测的差异：肇事者是股票的USB电缆将动车组0404来自它是最糟糕的是冠冕堂皇的（这也是建造不薄导线和铁素体屏蔽）。
这促使我购买怪兽，实线，贝尔金黄金，并最终Wireworld紫外线不同的USB电缆。他们都有着不同的声音，但听起来Wireworld明显优于它也允许在没有持久性有机污染物的沙沙声响，我的痛苦，达到与欧洲货币联盟0404usb最低的延迟设置。
Musiland Monitor 01 USD :
The Musiland Monitor 01 USD is a definite step up in sound quality compared to the EMU 0404 USB (and incedently compared with the usb input of the dac-19mk3).
The highs are cleaner and the bass tighter. The soundstage is a little bigger and there is better separation of the instruments.
I tried different latency settings with the asio control panel of the musiland but it didn't seem to affect much its sound performance. The good thing about the Musiland is it always operates without glitches whatever the load is on the cpu.
Finally, while it is not harsh sounding like the EMU 0404 usb, it lacks some of the sparkle and life that the better converters (teralink, hiface) seem to inject to music. It is not bad by itself but the music seems to be constrained and tight once it is compared with better units.
Note on usb cables :
While the async protocol should make the kind of usb cable that is used irrelevant, the Musiland is however still affected by the choice of the usb cable. It is probably because it draws its power from the computer but is also possible that is still affected by incoming jitter from
01美元的Musiland监视器是一个明确的步骤在声音质量达到欧洲货币联盟相比，0404的USB（和incedently与DAC的-19mk3 USB输入相比）。
高音和低音加强清洁。声场是有点大，有更好的仪器分离。
我已经尝试过了musiland ASIO的延迟设置不同的控制面板，但似乎没有影响到它的声音表现得多。关于Musiland的好处是它总是无故障运行无论是在CPU上的负载。
最后，虽然它不苛刻，如欧洲货币联盟0404的USB测深，它缺少的火花，更好的生活，转换器（teralink，hiface）似乎注入到音乐的。这是不坏，但由于它的音乐似乎受到限制和严密，一旦它更好的单位进行比较。
USB电缆的注意事项：
虽然异步协议应使USB线使用的那种无关紧要，但仍然在Musiland是受USB电缆的选择。这可能是因为它吸引了来自计算机的权力，但也有可能是仍然受到影响，从传入的抖动
Teralink-X :
When I bought the Teralink-X, I was not expecting much from it. At that time, I already had the Musiland unit and I was just curious to see how it performs because it uses high grade capacitors and a low jitter clock.
Straight out of the box it performed very well. After a few days of burn-in, the sound improved dramatically and it outperformed the Musiland unit easily.
The bass got deeper and more powerful, and the highs became more extended and sweeter at the same time. It is like lighting up a picture and discovering hidden details. But best off all, that increase in overall resolution did not increased the "edginess" of the sound. In fact, the sound became smoother.
The soundstage became bigger, almost limitless. In fact, on most recording I don't feel that I am listening to headphones, the only thing that keeps reminding that I am listening through headphones is the pressure of thesennheiser hd-650 on my head.
The imaging is precise, and hollographic in many recordings thanks to the precise separation of instruments and voices. Every instrument/singer has its own place on the soundstage.
Overall, I find the sound sometimes too good to be true. I got accustomed that only a few "audiophile" recordings sounded great in my system, however with theTeralink -X all recordings sound enjoyable in my system. I can still hear big differences between quality of recordings, the encoding used (mp3,flac, wav), but the Teralink-x, especially when paired with the Belden BNC cable, lets you focus on the positive sides of the recordings which is some might call "musicality".
Note on digital cables :
The Teralink-X works best in my system with the Belden BNC cable.
When paired with the Belden cable it gives a wide soundstage and a very smooth sound, "tubey like".
When paired with the Hifi Cables Sobek BNC cable, I get an increase in resolution, but a smaller soundstage and an increase in brightness "edginess".
当我买了Teralink - X的，我没想到太大了。当时，我已经有Musiland单位，我只是好奇，看它如何执行，因为它使用优质电容和一个低抖动时钟。
平直开箱它表现非常出色。经过几天的烧机，声音得到显着改善，并优于Musiland单位容易。
低音有更深入和更强大，变得更加的高点延伸，并在同一时间更甜。这就像点燃图片，发现隐藏的细节。但最好关闭所有，即在整体解决增加并没有增加声音的“急躁”。事实上，声音变得更顺畅。
声场变大，几乎是无限的。事实上，在大多数录音，我不觉得我听耳机，唯一让我提醒说，通过耳机收听是thesennheiser的HD - 650在我头上的压力。
成像精确，并且在许多录音hollographic感谢的声音精确的仪器和分离。每个仪器/歌手的声场及其对自己的位置。
总的来说，我觉得声音有时好得令人难以置信。我有一个习惯，只有少数“发烧友”的录音响起在我的系统非常然而，随着theTeralink - X，这都在我的系统声音录制愉快。我仍然能听到录音质量之间的巨大差异，所使用的编码（例如MP3，后手，WAV等），但Teralink - X的，特别是与贝尔登BNC电缆配对，让您专注于录音的是一些积极的一面可以称之为“音乐”。
数字电缆的注意事项：
该Teralink - X的作品在我与贝尔登BNC电缆系统的最佳。
当与Belden电缆配对它提供了广泛的摄影棚和一个非常平稳的声音“tubey像”。
当电缆带HiFi索贝克BNC电缆配对，我得到一个在分辨率提高，但在较小的声场和光明“急躁”增加。
Note on burn-in :
The Teralink-X needs a few days to sound its best. It doesn't sound bad at first but after a dew days of continuous play-back, the sound opened up and the bass got deeper. TheTeralink -X uses many capacitors inside that might explain the big change in sound that I did not notice to that extent (or at all) with the other converters
该Teralink- X需要几天时间来健全其最好的。这听起来不是在第一，但经过多年的不断回放一露天不好，声音开放和低音越来越深。 TheTeralink- X使用很多电容内这或许可以解释在声音大的变化，我没有注意到与其他转换器在该范围内（或全部）
M2Tech Hiface :
The m2tech hiface is my newest usb to spdif converter, I have only owned it for a few days, but I have listened to it for enough hours now to get a sense of how it sounds. This minuscule unit is simply outstanding.
First, the music just makes more sense. The notes flow more easily and it requires less efforts from the listener to understand what the performers were trying to convey. There is also a general increase in resolution that makes the music more real, probably because of its better retrieval of low level information on the recordings which makes reverbs and ambiance hall more audible in Live recordings and Classical music.
Second, the soundstaging is wonderful. It has a better pinpoint and 3D imaging than the other units, and there is a even better separation of instruments and voices. In fact, whether it is because of better imaging or because of better dynamics, the result is that instruments and voices seem to have more acoustic power (while playing at the same volume levels as I did with the other converters), the presence factor of performers and instruments is much higher.
Also, while the soundstage with the Teralink-X is big, there is not as much differentiation between recordings. With the hiface, the soundstage changes a lot (in width, depth and height) between different recordings.
Finally, the frequency extremes seem to have been extended with a more shimmering and extended highs and more articulate and tuneful bass. Compared to theTeralink -X, there is also a shift in the tonal balance to a more neutral and faithful balance. There is a better differentiation between the quality of the recordings and it doesn't impose a sound signature on the recordings : Warm recordings come out as such and over-processed recordings are highlighted as such but are still enjoyable to listen to.
Note on digital cables :
Differences between digital cables are more easily spotted : the Belden is muffled, there is also haze and distance to its sound which gave me the impression of a big and wide soundstage.
The Sobek has a better resolution, is razor sharp, highs are more extended, and the overall perceived volume is louder probably because there is more information coming through to the dac.
Once I bought the 18 ft. Belden cable, I didn't like the sobek as much as I used to before when I used it with the other converters because it was more honest and showed the shortcomings of those units.
With the hiface I can enjoy the high resolution sound provided with the Sobek.
Note on media players :
Since I have had the hiface only for a few days, I did most of my testing with foobar 0.8.3 and foobar 0.9.6.4 with KS.
I preferred the sound using the old foobar 0.8.3 but the current version of the driver has a bug with 0.8.3, the time slider of track doesn't move when playing.
I tested briefly MediaMonkey and I made the Hiface work with ASIO4ALL. Then I tried ASIO4ALL in foobar with the hiface and it worked but the sound quality was not as good as with KS.
Final note on the Hiface :
Each time I was doing A/B comparisons with one of the other units, I would end up listening to the M2tech and forget about my review. Unplugging it to put another converter was a tough experience each time because I had to be pulled out of the music.
Beyond the criteria I described above (soundstage, resolution, ...), the M2TECH hiface was the most satisfying unit from a sonic point of view as it was the closest to real representation and offered the most believable representation of music.
该m2tech hiface是我最新的USB到SPDIF的转换器，我只有拥有了数天，但我有足够的时间来听了，现在是如何得到它的声音的感觉。这简直是微不足道的优秀单位。
最初，这些音乐只是让更有意义。票据的流动更加容易，它需要较少的努力，听者明白表演者要传达。还有一个在第普遍提高，使音乐更真实更可能是因为其对录音使混响和氛围更大厅的现场录音和古典音乐声低级别的信息检索。
其次，声场是美好的。它具有更好的精确和三维成像比其他单位，并有一个仪器和声音甚至更好的分离。事实上，无论是因为更好的成像或由于更好的动力，其结果是，乐器和声音似乎有更多的声功率（而在同一音量播放，因为我与其他转换器一样），存在因素表演者和仪器要高得多。
此外，虽然与Teralink - X的声场大，没有太多的录音之间的分化。随着hiface，声场变化之间的很多不同的录音（在宽度，深度和高度）。
最后，极端的频率似乎已经延长和扩展更加闪耀的高点和更加明确和悦耳的低音。相比theTeralink - X的，也有在音调平衡转移到更为中立和忠实的平衡。有一间录音质量更好的分化，并没有强加给声音的录音签名：暖录音出来因此，过度加工的录音因此突出，但仍享受听。
数字电缆的注意事项：
数字电缆之间的差异更容易发现：在Belden是闷响，也有阴霾，距离其声音，给了我一大又宽音场的印象。
索贝克具有较好的分辨率，是锐利，高音有延伸，整体感知量高涨可能因为有更多的信息，敬请通过到DAC。
有一次，我买了18英尺Belden电缆，我不喜欢像我以前使用的时候，我用其他转换器是因为它是更诚实，发现这些单位的缺点，索贝克。
随着hiface我可以享受高解析度的声音与索贝克提供。
媒体播放器的注意事项：
由于我只有几天的hiface，我用foobar的0.8.3我的大部分foobar的测试与KS 0.9.6.4。
我更喜欢使用旧foobar的声音0.8.3，但当前版本的驱动程序有一个0.8.3的错误，时间的轨道滑块不动时播放。
我测试我和简要MediaMonkey与ASIO4ALL Hiface工作。然后我尝试ASIO4ALL与hiface在foobar的工作，但它的音质不如与KS好。
最后说明的Hiface：
每次我在做一个与其他单位之一/乙比较，我最终会听M2tech，忘记我的审查。拔掉它把另一转换器是一个艰难的经历，因为我每次都必须拉出来的音乐。
除了我前面的准则（音场，第...),的M2TECH hiface，描述了从一个角度声波点最满意单位，因为它是最接近于真实的代表性，并提供了音乐的最可信的代表性。 |
