【评测图文】不一样的东西就这么来了—SONCOZ SGA1 平衡放大器

The Power of Original Sound

来自美国媒体Headphonesty对SONCOZ SGA1全平衡耳机放大器的评测，这里截取了片段与大家分享。

结论

"The SONCOZ SGA1 is an intriguing and innovative device that brings many unique features to the desktop headphone amp category. I’m not entirely in love with the SGA1, but that being said, it works well and will likely remain as the anchor of my office desktop setup. I appreciate the high quality of the internal design and componentry."

SONCOZ SGA1 是一款有趣和创新的设备，为桌面耳机放大器类别带来了许多独特的功能。我并不完全喜欢 SGA1，但是，它工作得很好，并且可能会继续作为我办公室桌面系统的固定设备。我很欣赏它高品质的内部设计和元器件。

"The rear panel is pretty much par for the course for a combined preamplifier/headphone amplifier component. It has 3-pin XLR and RCA inputs and outputs, IEC   power socket,   input voltage selector (mine was set to 220V on arrival so pay attention before you plug it in), and the aforementioned power switch."

后面板是前置放大器和耳机放大器的组合器件。有3芯XLR和RCA输入输出，IEC电源插座，输入电压选择(出厂被设置为220V，通电之前要注意)，以及电源开关。

"The front panel couldn’t be any more streamlined, with 4-pin XLR and 4.4mm balanced outputs, 6.35mm SE output, OLED screen, and a single multi-use knob,   all contained in a rounded rectangular black glass panel."

前面板再简洁不过了，4芯XLR和4.4mm平衡输出，6.35mmSE输出，OLED屏幕，和一个多功能旋钮，所有都包含在一个圆矩形黑色面板中。

"The SGA1 mutes the output volume while making changes and fades it back in after complete, which is helpful to save your ears and equipment from any unintended selections."

SGA1在切换设置时会静音，设置完成后声音淡入，这保护了你的耳朵和设备免受意外影响。

"All the volume and gain options are thanks to the choice of implementing a MUSES 72320 digital volume control (resistance ladder circuit). The benefits of this design are perfect channel balance and accuracy from 0dB to -110dB, something that analog controls can only dream about."

所有音量和增益设置都是因为选择使用了MUSES 72320数字音量控制（电阻梯形电路）。这种设计的好处是实现完美的通道平衡和从 0dB 到 -110dB调整的准确度，这种精确的模拟控制是梦寐以求的。

"The remainder of the internal component choices seem top-notch: Muses OPAMPs (OPA1611, OPA1641, OPA1622 – headphone output buffer, OPA1661, and   OPA1641), ELNA and WIMA capacitors, anti-pop relay, and an internal toroidal linear power supply."

其他内部组件选择似乎是一流的：Muses OPAMP（OPA1611、OPA1641、OPA1622 – 耳机输出缓冲器、OPA1661 和 OPA1641）、ELNA 和 WIMA 电容器、防爆继电器和内部环形线性电源。

"The SGA1’s sound comes across as a touch warmer than truly neutral, and with a clean sonic signature. It doesn’t feel overly ‘digital’ or harsh sounding, and for the most part seems to keep out of the way of the music, delivering it without overt coloration."

SGA1 的声音比真正的中性更温暖，并具有干净的声音特征。它不会让人感觉过于“数字化”或刺耳，或在很大程度上感觉似乎远离了音乐，只是做没有任何感情色彩的传达。

"It’s not quite the sterile clean quality that the THX amps bring to the table, and has a slightly more organic character, likely due to those increased harmonics created by the digital volume control implementation. I expected to hear more significant differences based on the distortion measurement findings above, but in truth, it’s a well-mannered amplifier for most uses."

它并不完全像THX 放大器带来的枯燥乏味的干净音质，它具更多的自然特性，这可能是由于数字音量控制实现所产生的谐波增加。根据上面的失真测量结果，我预计会听到更显着的差异，但事实上，它是一个性能良好适用于大多数设备的放大器。

"The extension seems expansive, with no part of the frequency spectrum appearing clipped or unnaturally presented. If the source material is detailed, it comes through nicely from the SGA1, with nothing seeming boosted or overly clinical. It’s a solid performer, without any glaring sonic flaws, nor dazzling strengths."

声音的延伸似乎很广阔，频谱的任何部分都没有出现剪切或不自然的呈现。如果音源很详细，那么它很好地通过 SGA1，听起来没有任何夸大或过于冰冷的东西。这是一个坚实的表演者，没有任何明显的声音缺陷，也没有令人眼花缭乱的优势。

"As I expected from an amplifier seemingly designed to excel with high impedance loads, pairing the SGA1 with the 300 Ohm Sennheiser HD650 is a very successful combo with sufficient power and huge dynamics from both outputs. However, power limitations from the SE output are evident with the power-hungry planar Audeze LCD-2 headphones, even with the gain maxed out at 6dB."

正如我对一个似乎专为处理高阻抗负载而设计的放大器所期望的那样，将 SGA1 与 300 欧姆Sennheiser HD650配对是一个非常成功的组合，两种输出都具有足够的功率和巨大的动态。然而，对于平面Audeze LCD-2耳机来说，SE输出的功率限制是显而易见的，即使增益最大达到6dB。

"Using the convenient balanced cable and SE adapter included with the soon-to-be-reviewed HarmonicDyne Poseidon headphones, I can (somewhat) easily switch   between outputs. No question, there is far more power on tap from the balanced output and I’d recommend using this interface for most full-sized cans."

使用即将上市的HarmonicDyne Poseidon 耳机附带的平衡线和SE适配器，我可以（稍微）轻松地在输出之间切换。毫无疑问，平衡输出的功率要大得多，我建议大多数全尺寸设备条件允许都使用此接口。

"When using the fairly efficient (impedance: 23 Ohms, sensitivity: 112dB) Thieaudio Monarch IEMs, even with the single-ended output set to 6dB of gain,   it takes   about 50/100 on the volume control to achieve a moderate listening level."

当使用相当高效（阻抗：23 欧姆，灵敏度：112dB）的Thieaudio Monarch 入耳式耳机时，即使将单端输出增益设置为 6dB，音量控制也需要大约 50/100 才能达到中等的聆听水平。

"Appreciate it or not, SONCOZ is never a copycat brand, and Ben’s designs are always distinctive. Rather than pushing out an amplifier virtually indistinguishable from the pack, SONCOZ took a more controversial approach with the SGA1. The compromises made by the spartan accessories, digital volume control, variable power and gain, and the display interface will be embraced by some, and leave others nonplussed."

不管欣赏与否，SONCOZ 从来都不是山寨品牌，Ben的设计总是与众不同。SONCOZ 在SGA1 采用了更具争议性的设计，而不是推出一个几乎没有什么区别的放大器。简朴的配件、数字音量控制、可变功率和增益以及将被一些人接受，而让其他人感到困惑的显示界面。

"I admit, I’m not entirely in love with the SGA1, but that being said, it works well and will likely remain as the anchor of my office desktop setup. I appreciate the high quality of the internal design and componentry. Volume and gain memory, perfect channel match, and solid performance with high impedance headphones are all strong plusses in my books."

我承认，我并不完全喜欢 SGA1，但是，它工作得很好，并且可能会继续作为我办公室桌面系统的固定设备。我很欣赏它高品质的内部设计和元器件。音量和增益记忆、完美的通道匹配以及搭配高阻抗耳机的稳定性能都是在我文章中所描述的强大优势。
