感谢英国媒体The Audiophile Man对SONCOZ SGA1全平衡耳放前级一体机的评测（视频&文章），这里截取了片段与大家分享，原视频、文章请点击链接查看。

"I started in single-ended mode throughout via the HD800 headphones with a Kimber cable upgrade. I listened to CD and Depeche Mode’s Personal Jesus from the   album, Violator."

我在单端模式下使用HD800耳机，升级了线材。听了CD和流行音乐专辑Violator中的 Personal Jesus。

"The single-ended performance was interesting indeed because it offered a relatively even-toned, neutral presentation. There was no undisciplined frequency   emphasis here. No badly behaved mids or bass to cause listening fatigue. The basic, core sound here was clean and well mannered. "

单端表现确实很有趣，因为它提供了一个相对均匀的，中性的表现。这里没有随意的频率强调。没有表现不良的中音或低音导致听力疲劳。基本的，核心的声音在这里是干净和有礼貌的。

"The upper frequencies were surprisingly good in single-ended mode. There was much to like with good insight from the varied synth lines and   vocal delivery   providing good emotional insight. I was pleased to hear the emergence of quite shy elements across the wide soundstage. An acoustic guitar which appeared only of   a couple occasions was noted by the SGA1."

在单端模式下，高频出奇的好。各种合成器线路获得了良好的解析力，人声传递提供了良好的情感反应，这让很多人喜欢。我很高兴听到在宽阔的声场中出现了相当隐晦的元素。SGA1 注意到只出现过几次的原声吉他。

"I turned to a balanced headphone connection, a Pentaconn variant on my HD600 S headphones, to see if that might change anything. "

我转向平衡耳机，连接我的HD600S，看看这是否会改变什么。

"Now this was more like it! The detail from the mids remained, as did the dynamic reach around the upper frequencies in general terms. If anything, this area was extended tad. What really changed though was the improvement in tonal balance."

现在这更像是它！中频的细节仍然存在，总体而言，高频周围的动态范围也保持不变。如果有的话，这个区域被扩展了一点。真正改变的是音调平衡的改善。

"The bass was suddenly back and with some vengeance too. This track needs power to drive it forward and the balanced connection certainly provided that. The added mass gave the song drive, a forward motion that swung the hips and forced the head into a classical nodding configuration. "

低音突然回来了，带着一些报复。这首曲子需要动力来推动它前进，而平衡连接当然可以做到这一点。增加的能量为音乐提供动力，向前运动，摆动臀部并迫使头部进入经典的点头动作。

"The great thing about the balanced connection was that it introduced bass as a mature addition. It didn’t act like a Loudness button, swamping the soundstage with lower end frequencies in some sort of frantic torrent. "

平衡连接的伟大之处在于它引入了低音作为成熟的补充。它不像一个响度按钮，在某种疯狂的洪流中用低频淹没声场。

"Hence, the detail and the open nature of the midrange remained and that information was never masked. In fact, that same information now offered a maturity and richness which made this area all the more attractive."

因此，中频的细节和开放性仍然存在，而且这些信息从未被掩盖。事实上，同样的信息现在提供了一个成熟和丰富的音域，而这个音域更具吸引力。

"I then connected the SGA1 to my reference hi-fi in balanced mode, which added more maturity and a smoothing of the midrange. The upper frequencies as a whole   now glided across the soundstage in a relaxed and unhurried manner. The noise floor lowered appreciably here."

然后我在平衡模式下将 SGA1 连接到我的参考高保真音响，这增加了更多的成熟度和中频的平滑度。高频作为一个整体现在以轻松和不紧不慢的方式滑过声场。这里的底噪明显降低。

"All of which made the SGA1 sound, well sound more expensive frankly. The sound offered a luxurious playback now. More than that, the bass remained massy and powerful and still did not mask or veil detail yet was now better integrated into the mix as a whole. There was nothing flashy in the bass regions now. "

所有这些都让 SGA1 听起来不错，坦率地说听起来更贵。这声音现在提供了一种豪华的回放感。更重要的是，低音仍然厚重有力，没有掩盖或隐藏细节，但现在更好地融入了整个混音。现在低音区没有什么华而不实的了。

"This performance level was backed up when playing the vinyl version of ELO’s First Movement (Jumping Biz), an instrumental fronted by an acoustic (Spanish?) guitar and backed by violins and cellos plus percussion. The instrumental separation on this track allowed a heap of detail to spring forth. Each and every instrument on this track could be picked out and followed independently while each offered enough detail to the mix to delight the ear. "

在演奏 ELO 的第一乐章（Jumping Biz）的黑胶版时，这种性能水平得到了支持，这是一种以原声（西班牙？）吉他为前奏，以小提琴、大提琴和打击乐为伴奏的乐器。这首歌的乐器分离允许大量细节涌现。音乐里的每一个乐器都可以被挑选出来并独立跟随，同时每个乐器都为混音提供了足够的细节来取悦耳朵。

"As for the pre-amp section of this unit? I was impressed. Hooking up a pair of powered speakers like the Kanto YU4s, the speakers pushed up the sonic quality   ladder by a couple of rungs, adding a new even-handed sense of performance and a 3D effect around the central stereo image. Of course,   the Kantos were   hampered by their own inherent issues but the SGA1 still had them performing out of their skin, allowing these speakers to reach a level of midrange insight that they   could only have dreamed about previously. What the SGA1 gave to the Kanto powered speakers was a sense of the lively combined with enough raw quality that   allowed the Kanto speakers a real, skipping-through-the-daisies sense of fun. "

至于本机的前置放大器部分？让我印象深刻。连接一对像 Kanto YU4s 这样的有源音箱，这台音箱将音质提升了几个梯级，增加了新的均衡感和围绕中央立体声图像的3D 效果。当然，Kantos 受到了他们自身固有问题的阻碍，但 SGA1 仍然让他们表现出色，让这些音箱能够达到他们以前只能梦想的中频解析力水平。SGA1 给 Kanto 有源音箱带来了一种活泼感和足够的原始素质，让 Kanto 扬声器真正地有在雏菊中跳舞的乐趣感。

"As a pre-amp, the SGA1 is a valuable addition to any small footprint hi-fi system. It can lift other low-cost components to a higher level. Giving the system as a   whole a sheen of quality.   I wouldn’t buy the SGA1 purely as a pre-amp but it’s a great bonus for anyone looking for a headphone amplifier. "

作为前置放大器，SGA1 是任何小尺寸高保真系统的宝贵补充。它可以将其他低成本组件提升到更高的水平。使整个系统变得高质量。我不会纯粹作为前置放大器购买 SGA1，但对于寻找耳机放大器的任何人来说，这是一个非常好的选择。

"If you do run balanced hardwire though, well that’s a different story and the Soncoz is a wholly different beast in this mode. "

如果使用平衡连接，那么就是另外一个故事了，SONCOZ在这种模式下是完全不同的野兽。

"When balanced mode was introduced, the SGA1 sprang to life and put on a real show. Detail and information now revealed itself upon a firm and solid foundation. The resultant tonal balance produced a seasoned and abundant soundstage that was full of individual highlights for the ear to pick out. "

连接平衡模式后，SGA1 焕发生机并进行了真正的表演。现在，细节和信息在坚实的基础上显露出来。由此产生的音调平衡产生了一个内容丰富的声场，充满了精彩的亮点供耳朵挑选。

"To confirm, as a headphone amplifier, I would only look to buy the SGA1 if you have a pair of balanced headphones and/or a balanced connection from your supporting hi-fi chain. Balanced mode provides a suite of sonic highlights and provides a top notch, mature sound. If you can go balanced, you’ll have a great time with the   SGA1."

肯定的是，作为耳机放大器，如果你有一个平衡耳机或你的HiFi系统支持平衡连接，我只会想买 SGA1。平衡模式提供了一套声音亮点，并提供一流的成熟声音。如果你有平衡连接，那么将在 SGA1 上度过愉快的时光。
