【评测图文】SONCOZ SGA1评测分享 | "Wild Wild East"狂野的东方

The Power of Original Sound

前言

翻译的时候卡在第一步很久——标题"Wild Wild East"是什么意思呢？第一反应是狂野的东方，但是Wild重复是否有什么暗示和联想？做了各种猜想后还是去联系了原作者求教。以下原话：

"Wild Wild East" is a response to the Wild Wild West movie. I wanted to outline that you are making things differently compared to other audio brand. Hence the "Wild Wild moniker" highlighting your wild and different way of designing. 《Wild Wild East》是对《Wild Wild West》电影的回应。我想表达的是你所创造的东西与其他音频品牌有所不同。因此，“狂野的绰号”是突出你狂野和与众不同的设计方式。

结论

"Soncoz proved that not all chip-based amplifiers are sounding achromatic, lean or boring. Its overly engineered power supply and filtering stages paid off big time,   improving its timing, adding weight and fullness and dropping its noise floor into the abyss. SGA1 is an outstanding proposition for people that use multiple headphones on a daily basis. Be them overly sensitive IEMs or heady-duty planars,   it drove them all preserving their unique character,    while adding   a pinch of   naturalness   into the mix." — Sandu Vitalie (SOUNDNEWS 原文链接)

Soncoz 证明，并非所有基于芯片组的放大器听起来都是无色、精简或乏味的。其花费巨大精力设计的电源和滤波方案获得了巨大的回报，改善了延迟，增加了重量感和丰满度，并将其本底噪声降低到了深渊。对于每天使用多个耳机的人来说，SGA1 是一个非常好的选择。无论是过于敏感的入耳式耳机还是重负载的平面耳机，都让它们保留了其特性，同时在混合搭配中添加了一点自然感。

设计与工艺

"As you can expect, SGA1 looks and feels exactly as their top-of-the-line SGD1 DAC and you can stack them together for a visually stunning combo.   Forget about   complicated UI’s or hidden menus that can be accessed only by a remote control, as I’m dealing with a clever and extremely user-friendly interface.   I find it so simple, yet modern and exquisite looking."

不出所料，SGA1 的外观和触感与他们的SGD1 DAC 完全一样，你可以将它们堆叠在一起以获得外观上令人惊叹的组合。忘记只能通过遥控器访问的复杂的用户界面或者隐藏的菜单吧，因为我正在用一个聪明、对用户非常友好的界面。我发现它很简单，但外观时尚而精致。

"SGA1 isn’t that heavy, but always gives an impression of a well-engineered and well-made product. From a big majority of DAC and headphone amplifier   manufacturers coming out of Asia, Soncoz has definitely one of the best looks and form factor."

SGA1并不笨重，但总是给人一种精心设计、制作精良的印象。来自亚洲的绝大多数 DAC 和耳机放大器制造商中，Soncoz 绝对是外观和外形最好的之一。

内部设计

"By far, the most interesting part about SGA1 is its power supply design. It uses a custom-made toroidal transformer that is encapsulated with permalloy,   shielding it from sensitive analog circuitry. If that doesn’t sound like enough, to further suppress the 50 Hz and 60 Hz noise, they’ve added a layer of magnetic stainless-steel baffle that works as a secondary line of defense, stopping all remaining noise and acting as a passive power conditioner in the process. "

目前为止，SGA1 最有趣的部分是它的电源设计。它使用定制的环形变压器，用坡莫合金做屏蔽层，使其免受敏感模拟电路的影响。如果这听起来还不够，为了进一步抑制 50 Hz 和 60 Hz 噪音，他们增加了一层磁性不锈钢挡板，作为第二道防线，阻止所有剩余的噪音，并在过程中起到被动电源净化的作用。

"The absolute last line of defense is formed by a bunch of analog relays that can save your precious headphones from pops and crackles."

最后一道防线由一堆模拟继电器构成，可以保护你珍贵的耳机免受爆破音和噼啪声。

初步声音印象

"I have op-amps in a lot of headphone amps: Benchmark HPA4 ($3000) is full of them, Topping A90 and A30 PRO are also using op-amps as their driving force.   NFCA modules of Topping, PLFC modules of SMSL and AAA modules of THX are using op-amps and those are still unbeatable when it comes to high SNR and   super-low THD numbers. With all that said…when putting my headphones on, something was missing with such amplifiers and it’s difficult putting a finger   on what that was, explaining with mere words without taking a listen isn’t that easy. Something wasn’t clicking into place, making my tunes ruler flat, barely transmitting emotions or making me move to the rhythm of the music, but that is going to change with the amplifier that I’m testing today. Soncoz went with a dozen of OPA’s from Texas Instruments, but they had a different philosophy to everything that surrounds them, starting with power supply and noise suppression and then finishing with the filtering stages, Soncoz put their bright minds in delivering something else, something that wasn’t rushed, but made with dedication and care."

我的很多耳机放大器中都有运算放大器：Benchmark HPA4（3000 美元）里面都是，Topping A90 和 A30 PRO 也使用运算放大器作为驱动力。Topping的NFCA模块、SMSL的PLFC模块和THX的AAA模块都使用了运放，在高SNR和超低THD数方面仍然是无与伦比的。话虽如此……当我戴上耳机时，这种放大器缺少一些东西，很难弄清楚那是什么，在不试听的情况下用文字解释并不是那么容易。有一些没有到位，让我的曲调变得平缓，几乎无法传达情感或者让我跟随音乐的节奏律动，但这将随着我今天测试的放大器而改变。Soncoz 使用了来自德州仪器 (TI) 的十几种 OPA，但他们对周围的一切都有不同的理念，从电源和噪声抑制开始，然后是滤波方案，Soncoz 将他们聪明的头脑放在提供一些产品上，这些产品不是仓促完成而是尽心尽力精心做出来的。

"All those things combined, transformed an op-amp based amplifier into something that doesn’t sound like one, reminding a whole lot more about all-discrete, transistor-based amplifiers that were biased into Class-A operation. This isn’t an exaggeration from my part, not a slightest,   as SGA1 was able to awake   emotions in my music and made me feel good, it made me toe-tap, stopping from whatever I was doing in front of my PC. It captured my attention with a powerful   low-end   delivery, with a fuller-midrange and with and soul-grabbing vocal performance. I find it honest and detail-oriented, very much in line with   the latest releases   from Asia, but it wasn’t an extremely linear or flat sounding unit. There is a nicer saturation in the midrange that improved the vocal performance and I never   experienced   listening fatigue in a two-week period. SGA1 would never remind about the sound of THX-AAA, NFCA or PLFC designs, that I am getting bored of   as of late."

所有这些结合起来，将基于运放的放大器变成了一种听起来不像放大器的东西，让人想起更多关于偏向 A 类的全分立、基于晶体管的放大器。我一点也不夸张，因为 SGA1 能够唤醒我音乐中的情感，让我感觉很好，它让我踮起脚尖，停止在电脑前做的任何事情。它以强大的低音传递、更饱满的中频和引人入胜的人声表现吸引了我的注意力。我发现它诚实且注重细节，非常符合亚洲的最新版本，但它并不是一个非常线性或单调的单元。中音有更好的饱和度，提高了人声表现，我在两周内听音乐从未感到过疲劳。SGA1永远不会让我想起最近厌烦的 THX-AAA、NFCA 或 PLFC 设计的声音。

"Exchanging DACs with the SGA1 on top, made me realize that I’m dealing with a clean sounding unit that would never stay in front of the musical signal. No matter if it was the Audiobyte HydraVox, the Matrix Audio Element X or the the SMSL D1SE, it wasn’t staining their tonality, leaving their mark unchanged, adding just a bit of smoothness and soul into music. In all seriousness, it wasn’t making my headphones bright or harsh sounding, even entry-level Hifiman headphones sounded   organic, teleporting treble ringing and glare into a distant past, preserving cleanness and detail-oriented nature of higher-end headphones. SGA1 doesn’t seem like   another headphone amplifier coming out of China, this is something else entirely that cares about the final outcome, transmitting a clear message and imbuing   your music with positive emotions. That’s a hell of a first impressions lads, but let’s carry on and try a bunch of headphones."

给SGA1 换上不同的DAC，让我意识到我正在研究的是一个声音干净的单元，它永远不会停留在音乐信号之前。无论是 Audiobyte HydraVox、Matrix Audio Element X 还是 SMSL D1SE，它都没有改变它们的音色，始终保持它们的特点不变，只是为音乐增添了流畅性和灵魂。严肃地说，它并没有让我的耳机听起来明亮或刺耳，即使是入门级的Hifiman 耳机听起来也很自然，将高音铃声和刺耳的声音传送到遥远的地方，保持了高端耳机干净和注重细节的特性。SGA1看起来不像是又一个来自中国的耳放，这是另一种只关心最终结果的东西，传递一个明确的信息，让你的音乐充满积极的情绪。第一印象真是太棒了，让我们继续尝试一些耳机吧。

功率输出

"Going by a (silly) rule of thumb that most planar-magnetics need a least a few watts of power to be moved and controlled, then SGA1 can’t possible do that and it   should be shy and unimpressive with most of them, right? That’s wrong! Be them desktop dynamic headphones or low-sensitivity ones, SGA1 didn’t pose a slightest   problem with them all. It was still controlling those drivers, it was still pumping dynamics even with harder loads as Hifiman HE1000SE, Audeze LCD-4 and   Sendy Peacock.   LCD-4   is a huge burden for most affordable amplifiers and yet, with 16 dB of volume remaining on tap, leaving enough headroom behind, LCD-4   were sounding exactly as I know them with my upper-class amplifiers.   Even reference recordings with a DR of -14dB didn’t pose a problem to the Soncoz unit and   LCD-4 were still highly engaging and toe-tapping all the time. Honestly, from my growing headphone collection, LCD-4 sounded the absolute best, just amazing and   extremely engaging, a thing I wouldn’t say about most amplifiers in this price range. I’m not sure if their 200 Ohm impedance plays a major role – a region   where   SGA1 would provide considerably more power, but I couldn’t stop smiling and air guitaring when the Soncoz amp was driving them. Treble oriented headphones as   Hifiman HE1000SE were also spectacular with it, as it was able to infuse just a small dose of dopamine in the midrange, while calming down the treble grittiness and   listening fatigue. HE1000SE sounded as if I magically shrunk that Flux Labs Acoustics Volot ($2550) into a smaller case and left its voicing untouched, it made them alive sounding and a lot more manageable in long listening sessions. This was an amazing pairing that I wouldn’t forget very soon."

根据一个（愚蠢的）经验法则，大多数平面磁性耳机需要至少几瓦的功率来推动，那么SGA1 不可能做到这一点，而且对于大多数来说，它并不引人注目，对吧？那是错误的！无论是桌面动圈耳机还是低灵敏度耳机，SGA1都没有丝毫问题。它仍然驱动着那些耳机，即使在 Hifiman HE1000SE、Audeze LCD-4 和 Sendy Peacock 等更重负载的耳机下，它仍然能提供动力。LCD-4 对于大多数便宜的放大器来说是一个巨大的负担，然而，由于有16dB的音量空间，留下了足够的动态余量，LCD-4 听起来和用我的高级放大器推完全一样。即使 DR 为 -14dB 的参考录音也不会对 Soncoz 单元造成问题，而LCD-4 仍然具有很高的吸引力，一直是轻松明快的。老实说，从我不断增加的耳机收藏中，LCD-4 听起来绝对是最好的，令人惊叹且极具吸引力，对于这个价格范围内的大多数放大器，我不会说这一点。我不确定它们的 200 欧姆阻抗是否起主要作用——在这个区域SGA1将提供更大的功率，但当 Soncoz 放大器驱动它们时，我无法停止微笑和播放弹吉他的音乐。高频导向的Hifiman HE1000SE在SGA1的驱动下也很出色，因为它能够给中音增添些许情绪，同时缓解高音的粗糙感和听觉疲劳。HE1000SE 听起来就像我神奇地将 Flux Labs Acoustics Volot（2550 美元）缩小到一个更小的盒子里，并保持它的声音不变，SGA1使它们听起来很生动，并且在长时间的聆听过程中更易于控制。这是一个令人惊叹的组合，我不会很快忘记。

底噪

"You’ve guessed it: we are dealing with a silent amplifier that could be used with IEMs even on its highest gain. I didn’t expect less with a measured noise floor of 1.8 micro-Volts on its SE output and double that number on its balanced outputs. That’s a very low noise-floor, not exactly world-class performance as there are several   units that were more impressive in here, but I can’t deny its clean and undistorted nature with anything attached to it, including sensitive IEMs."

你已经猜到了：我们正在经历的是一种静音放大器，即使在其最高增益下也可与入耳式监听耳机搭配使用。我没想到它的SE输出的实测底噪为 1.8 微伏，而其平衡输出的底噪增加了一倍。这是一个非常低的底噪，不完全是世界一流的性能，因为这里有几个更令人印象深刻的单元，但我不能否认它驱动任何东西声音干净和不失真的特性，包括敏感的入耳式监听耳机。

" I’ve tried a few more IEMs and it offered a pitch-black background and a noiseless performance even at higher SPL. I even compared it with a noise-killer champion: the mighty Benchmark HPA4 and sure enough, SGA1 was a tiny bit noisier at maximum volume and that is an outstanding result, considering that it costs ~4.6 times cheaper than the HPA4. Of course, nobody can listen at that volume, that amount of power would damage the IEMs and my ear-drums in a split second, so again great results in both cases. Only close to its maximum power, there was a faint white noise hidden in the background that can be considered as normal behavior. At normal listening levels, you can happily drive highest sensitivity IEMs on high gain and you’ll get the same outstanding results."

我在更高的声压下尝试了更多的IEMs，它也能提供漆黑的背景和无噪音的性能。我甚至将它与强大的 Benchmark HPA4进行了比较，果然，SGA1 在最大音量下噪音稍大，考虑到它的成本比 HPA4 便宜约 4.6 倍，这是一个出色的结果。当然，没有人可以在那个音量下听，那么大的功率会在一瞬间损坏耳机和我的耳膜，因此在这两种情况下都取得了很好的效果。只有接近其最大功率，背景中隐藏着微弱的白噪声，这可以认为是正常的现象。在正常聆听水平下，你可以愉快地以高增益驱动最高灵敏度的入耳式监听耳机，并且获得同样出色的效果。

"Any other IEM, portable over-ear and sensitive desktop headphone performed very similar and couldn’t pick its noise floor at my usual listening levels."

任何其他 IEM、便携式耳罩式和灵敏台式耳机的表现都非常相似，无法在我平常的听力水平上确定它的底噪下限。

解析力和透明度

"When it was driving the mighty Susvara, it delivered clean sonics in a very transparent way, never downgrading their resolute-nature and never lowering their   technicalities. Going through a huge music collection, covering a wide range of musical genres, I can safely say that SGA1 chooses a see-through transparency and   a high resolution even past top-octave. Did I hear additional micro-details compared to   something like a   Musician Andromeda,   Gustard H16 and to   smaller units like xDuoo XA-10? Sure, I did and all that was presented in a very relaxed and non-aggressive way. While being extremely textured and clean, its top-end was never   bothering or dry sounding. "

当它推强大的 Susvara 时，它以非常透明的方式传递干净的声音，从不降低其坚毅的本性，也从不降低其技术性。听过涵盖了广泛的音乐流派的庞大音乐收藏后，我可以肯定地说，SGA1 选择了极清晰的透明度和高解析力，即使是高频。与 Musician Andromeda、Gustard H16 和 xDuoo XA-10 等较小的装置相比，我是否听到了更多的微观细节？当然，我做到了，所有这些都以非常轻松和自然的方式呈现。非常有质感和干净，高音也从不突兀或干涩。

"Another interesting trait is that while being clean and detailed at all times, it never forced me looking at those details. Snare drum hits and cymbal crashes stood out with their natural metallic bodies, without adding unwanted ringing and shrillness that several amplifiers are putting on a plate."

另一个有趣的特点是，虽然始终保持干净和详细，但它从不强迫我去专注这些细节。军鼓敲击声和镲片敲击声以其天然的金属特性脱颖而出，放大器没有增加不必要的振铃和刺耳的声音。

瞬态响应

"Audeze LCD-4 and Hifiman HE1000SE were mating with SGA1 as Ying does with Yang, taking all their pluses and adding some flavor into the mix. Add faster   decays and you can almost imagine that it kept up with a rising tempo and it was propelling those bass notes back and forth like a machine gun, easily passing my   transient   response tests with high marks."

Audeze LCD-4 和 Hifiman HE1000SE 与 SGA1 搭配，就像阴与阳一样，充分利用各自所有优点，并在混合中添加了一些味道。加上更快的衰减，你可以想象它始终跟着快速的节奏，像机关枪一样来回推动这些低音音符，轻松通过我的瞬态响应测试并获得高分。

"There’s one good thing that was clear from the start, it mates well with all my digital sources and its impactful and lively sound signature would always carry over. No matter if you’re using entry or high-end converters, it would always deliver a nicer impact down low."

有一件很好的事情从一开始就很清楚，它与我所有的数字音源都很好地配合，其有力和生动的声音特点将一直延续。无论使用的是入门级还是高端的转换器，它总能在低音产生更好的影响。

声场和深度

"While it wouldn’t outperform the likes of Flux Lab Acoustics FA-10 ($750) and Burson Soloist 3X ($1200) in terms of scale, it outplayed several chip-based amplifiers like Topping A90 ($500), SMSL SP400 ($630) and Musician Andromeda ($870), so there is still a decently sized soundstage and a pretty good depth.Due to its clean and detailed sounding nature, without adding any noise into the system, pin-point location of all the notes around me felt precise and I could easily   focus on anything in particular. There are thousands of tracks that carry tens of instruments, from which a single one could steal my heart and with such music it was   extremely easy focusing on that particular instrument, without closing my eyes. It scored another point when I was digging deep into my music, I could easily appreciate the distance between every musical note and myself, leading towards an outstanding depth. It seems that it will not artificially boost the soundstage size, as it might happen with few tube amplifiers and it will render all that information as close as possible to the original intent of the mastering engineer. It sounds slightly bigger, wider and taller with live music and the other way around with cozy blues and jazz recordings."

虽然它在等级上不会超过Flux Lab Acoustics FA-10（750 美元）和Burson Soloist 3X（1200 美元）之类的产品，但它胜过Topping A90（500 美元）、SMSL SP400（630美元）、Musician Andromeda（870 美元）等几款基于芯片组的放大器。它仍然有一个相当大的声场和相当好的深度。由于其干净而细致的声音性质，不会在系统中添加任何噪音，我周围所有音符的定位感觉很精确，我可以轻松地专注于任何特定的东西。有数千首曲目携带数十种乐器，其中有一种可以抓住我的心，在这样的音乐中，我很容易专注于某个特定的乐器，无需闭上眼睛。当我深入挖掘我的音乐时，它又得分了，我可以轻松地体会到每个音符与我自己之间的距离，从而达到出色的深度。它似乎不会人为放大声场大小，因为它可能发生在少数电子管放大器上，并且它会将所有信息尽可能接近母带工程师的原始意图。现场音乐听起来更大、更宽、更高，而舒适的蓝调和爵士乐录音则相反。

频率响应

"SGA1 is a wide-bandwidth amplifier, covering the frequency response in full. While it adds some texture and weight in its low and mid-regions, its frequency   response feels straight as a line, as everything seems to play at the same SPL."

SGA1是一种宽频响放大器，完全覆盖音频范围。虽然它在低频和中频区域增加了一些质感和重量，但它的频率响应感觉就像一条直线，因为一切似乎都在相同的声压下播放。

A.低音

"When I’ve heard some outstanding bass lines with the Susvara, it was clear that I’ll have the same results with any other headphone. There is a good extension down-low, a controlled sustain and a natural decay of the bass. It never lingered for a micro-second longer, it was always on   time, precise, fast and impactful sounding. Weight and fullness would be nothing without air, layering and cleanness, luckily, I find its low-end   clean and completely noise-free. Low-intensity notes have enough air and are never slipping over the midrange area. This is a high-quality type   of bass that I wish all chip-based amplifiers would have. Mid-bass felt exactly as powerful and bold, adding a higher density and a sense of fullness all the time."

当我听到 Susvara 的一些出色的低音线时，我用任何其他耳机也能获得相同的结果。低音有很好的延伸，可控的延音和自然的低音衰减。它从来没有停留过一微秒，它总是准时、精确、快速和有力的声音。如果没有空气感、层次感和清晰度，重量和丰满度将一无是处，幸运的是，我发现它的低音干净且完全无噪音。低强度音符的有足够的空气，永远不会滑过中音区域。这是一种高质量的低音，我希望所有基于芯片的放大器都能拥有。中低音感觉同样雄厚有力，不断增加更高的密度和丰满感。

B.中音

"One of the biggest highlights of SGA1 is that it never sounded dry or thin in the midrange, on the contrary it added more energy in there, creating a believable and a soothing vocal performance. My folk, blues, jazz and rock collections sounded alive and quite natural, exactly as I know them to sound on all-discrete amplifiers. Soncoz added just a pitch of warmth and naturalness that popped its midrange, pushing it closer towards   the listener. It was a paradox, as some of my older recordings appeared detailed, but also organic and alive, usually it’s one of the other. In the   end, I wouldn’t describe it as overly warm or overly dense sounding unit, it was more about being honest, while fully preserving the weight, the   innards and the naturalness of the midrange. Going slightly higher on its volume didn’t make it aggressive, it was still cruising around, adding   smoothness and a sense of calm."

SGA1 最大的亮点之一是它的中音从不枯燥或单薄，相反，它在那里增加了更多的能量，创造了真实而舒缓的人声表现。我收藏的民谣、布鲁斯、爵士和摇滚听起来既生动又自然，就像我在全分立放大器上听到的声音。Soncoz 只是增加了一点温暖和自然的音调，使中频突出，更靠近听众。这有点矛盾，因为我的一些较旧的录音听起来很详细，也有自然和生动，但通常只有其中一个特点。最后，我不会把它描述为过于温暖或过于密集的声音单元，它更多的是诚实，同时充分保留中音的重量、结构和自然度。稍微提高音量并没有让它变得有攻击性，在音乐播放中增加了平滑感和平静感。

C.高音

"Another interesting aspect is that no matter the song I would listen to, it wouldn’t make it harsh with bright tilted headphones as Hifiman creations. Treble felt highly detailed and precise, unfolding everything past top-octave without too much trouble. Double drums were fast, clear and defined, snare drum hits were impactful   and tambourines were metallic sounding, but never bothering. My rock and metal tunes didn’t pose a slightest problem even with the Hifiman HE1000SE on my head. The usual grain and over-sharpness of several THX-AAA amplifiers was forever gone, never to be spotted on the SGA1. It tamed their hot treble, while preserving its   detailed and clean performance."

另一个有趣的方面是，无论我听哪首歌，即使用像Hifiman这种偏明亮的耳机也不会让音乐变得刺耳。高音感觉非常详细和精确，展现超过最高八度音域的所有内容都没有太多问题。双鼓快速、清晰和明确，军鼓打击有力，手鼓发出金属般的响声，但不觉得很吵。即使将 Hifiman HE1000SE 戴在我的头上，我的摇滚和金属音乐也丝毫没有问题。几款 THX-AAA 放大器通常的颗粒感和过度锐利已经一去不复返了，永远不会出现在 SGA1 上。它驯服了他们的高音，同时保留了其详细和干净的性能。

"Overall, I wouldn’t describe it as warm, thick, bright, lean or mellow sounding. I would describe it as natural sounding, true to the recordings, linear and extended in the frequency response, covering it in full."

总的来说，我不会把它描述为温暖、厚实、明亮、精瘦或圆润的声音。我会把它描述为自然的声音，真实的还原，线性和扩展的频率响应，完全覆盖它。

总结

"offering plenty of technicalities, while preserving the liquidity and soul of the music. It worked exceptionally well with brighter headphones, smoothing-out their leading edges and boosting their tonality. It paired outstanding with Audeze and Hifiman headphones and it should perform very similar with dynamic diaphragms. All things considered; it’s asking price of $650 is fully justified. It scored a Silver Award and I cannot wait to find out what’s coming next."

提供了大量的技术细节，同时保留了音乐的流动性和灵魂。它与更亮的耳机配合得非常好，平滑了它们的前沿并提高了它们的音调。它与 Audeze 和 Hifiman 耳机搭配得非常出色，它应该与动态振膜的表现应该非常相似。所有的情况都被考虑到了，SGA1售价650 美元是完全合理的。它获得了银奖，我迫不及待地想知道接下来会发生什么。
