Soulution720前级710后级
Soulution 720前级710后级Soulution 720前级+710后级000作为Hi-End音响界的新秀，瑞士Soulution推出的产品不多，却有著硬底子真功夫。
在聆听篇当中，我们已经从赖英智的字里行间，神游Soulution 720前级与710后级搭配Eventus Nebula喇叭所重现的美声，接下来让我们看看720前级与710后级，究竟里面装了什麼好料，值得不凡身价。
先讲Soulution 720前级Soulution 720这部面板只有二个旋钮的重量级前级扩大机（重达30 公斤，很多功率后级的重量还比它轻呢！），搭配一个可以藏在掌心的迷你遥控器，除了媲美第一流瑞士钟表的金属加工外，第一眼实在不清楚它有什麼特别。
Soulution 720前级外观简洁典雅，光从外观很难想像其技术之高超，但金属加工的光泽与质地，则是绝对第一流的水准，完全符合瑞士精致工业的内涵。
根据厂方的介绍，内建唱头放大线路的720前级采非平衡结构，因为越少的零件才能达到最低失真的要求，不过720前级仍提供XLR输入与输出方便用家搭配，当然建议使用RCA接线最好。
720前级看似简单却有丰富聪明的功能，每组输入都能更改命名，调整3/6/9dB的增益，另外有调整频宽的特殊设计。
放在High时频宽不设限制，放在Mid时200kHz时衰减3dB，放在Low时20kHz衰减3dB，以数位讯源连接时建议放在最高1MHz的频宽。
由於Soulution连DC都能放大，所以使用时面板显屏中偶会有红灯亮起，这是侦测到线路中有DC直流存在的警示，如果直流高於15mV，保护线路便会启动一枚交连电容到放大线路，以策安全，当直流降低，15秒后保护线路又会自动关闭。
从完善复杂的保护线路，到720使用的WBT新型Nextgen插座，我们可以知道设计者的用心。
Soulution 720前级采用视讯用的放大晶体，一方面频响响应性能高，一方面能降低输出阻抗，输出峰值电流达到3安培。

ＳＯＮＹ耳塞王朝大阅兵
ＳＯＮＹ⽿塞王朝⼤阅兵1982年，SONY推出了其⽿塞产品的开⼭之作，MDR-E252，时⾄今⽇20余载，建⽴了⽆⼈能⽐的⽿塞王朝，型号多得让⼈眼花缭乱，其中当然不乏为⼈津津乐道的经典之作，虽然SONY如今的⽿塞造诣已不如从前，但是SONY的⽿塞⽂化着实影响了不少⼈，不论是以前2系列，4系列，5系列，还是现在的9系列，EX系列，SONY都在继续书写着⽿塞的历史。
在随⾝听⽿塞产品的发展历史上，能够与SONY⽿塞数量和质量相媲美的品牌⼏乎没有，其⽿塞产品型号通常以MDR-E开头，MDR是SONY⽿机产品通⽤型号字头，E则代表EARPHONE（但是也有另外，⽐如MDR-B114，NC系列，ED系列）。
MDR-E后⾯仅跟三位数字，第⼀个如果是数字的话则⼤致代表⽿塞出⼚年代的早晚，2为最早，9为最新；第⼆位数字则代表该型号⽿塞产品体系中的地位，越⼤越⾼档（但是并⾮绝对，⽐如MDR-E757）；最后⼀个字母若与第⼀个相同表明这款⽿塞为主流⽿塞，若不相同则属于旁系⽿塞。
另外还有其他⽐如ED，EX，NC系列等等众多⽿塞，鉴于⾄今没有见到⼀篇⽐较全⾯的对全线产品介绍的⽂章，笔者就对SONY的⽿塞产品做⼀次⽐较全⾯的介绍......2系列MDR-E212/214/215/222：⽇本制造，2系列最低端型号，造型结构和声⾳风格⼤同⼩异，13．5MM单元，21*和222的区别仅仅在于线材⽅⾯，21*使⽤廉价单股线，222则采⽤成本较⾼的双股线，⽽215则是212的防⽔版，214则是早期⼀些内藏⽿塞机器的配机⽿塞（⽐如1987年2⽉发售的WM-51），由于线材的关系，222会⽐21*略好⼀些，这⼏款⽿塞价格⽐较便宜，尤其是215，现在常常能见到。
虽然价格低廉，但是表现却很不错，属于廉价却不低档的⽿塞，中⾼频出⾊清亮，声场⾮常⼴，凝听⼈声更会让您体会到这⼏款⽿塞的超值之处，但是从21*/222开始到如今的930，⼏乎所有使⽤⼩⼝径单元的⽿塞都有⼀个缺点，低频不强，⽋缺量感。

Doing so could result in personal injury and/or product failure.CAUTION: Ignoring these cautions may cause moderate injury or property damage as a result of incorrect operation.Never disassemble or modify the device, as failures may result.Do not subject to extreme force and do not pull on the cable or failures may result.Keep the microphone dry and avoid exposure to extreme temperatures and humidity.General DescriptionThe Shure SM7dB dynamic microphone has a smooth, flat, wide-range frequency response appropriate for content creation, speech, music, and beyond. A builtin active preamplifier provides up to +28 dB of lownoise, flat, transparent gain while preserving frequency response for a clean, classic sound. The SM7dB's built-in preamp delivers the legendary sound of theSM7B, completely uncompromised and without the need for an inline preamplifier. The SM7dB back panel switches allow customized frequency response and the ability to adjust or bypass the preamp.Powering the SM7dB PreamplifierImportant: The SM7dB requires +48 V phantom power to operate with the preamplifier engaged. It will operate in bypass mode without phantom power.To deliver audio directly to a computer, use an audio interface with an XLR input that provides +48 V phantom power, such as the Shure MVi or MVX2U, and turn phantom power on.When connecting to a mixer, use only balanced, microphone-level inputs with phantom power. Turn phantom power on for the channel your SM7dB is connected to.Depending on your interface or mixer, phantom power may be enabled through a switch, a button, or control software. Refer to the user guide for your interface or mixer to learn how to engage phantom power.Preamplifier Best PracticesThe SM7dB features a builtin active preamplifier which provides up to +28 dB of lownoise, flat, transparent gain that optimizes audio performance.Adjust the gain level on the SM7dB before adjusting levels on your interface or mixer. This approach maximizes the signal-to-noise ratio for a cleaner, clearer sound.In podcast or quiet vocal applications, you are more likely to need the +28 dB setting, while louder talkers or singers may only need the +18 dB setting. For instrumental applications, you may find that the +18 dB or the bypass settings reach the ideal input levels.Using Variable Impedance Mic PreamplifiersSelect the highest available impedance setting on the external preamp when using the built-in preamp.If you are using a low impedance setting to change the tonality for creative purposes, bypass the SM7dB's built-in preamp. Keeping the SM7dB preamp engaged with a low-impedance setting will not yield the same changes in tone.Microphone PlacementSpeak directly into the mic, 1 to 6 inches (2.54 to 15 cm) away to block offaxis noise. For a warmer bass response, move closer to the microphone. For less bass, move the microphone away from you.Velcro Cable TieUse the enclosed velcro tie to secure the cable.WindscreenUse the standard windscreen for general voice and instrumental applications.When you speak, you may hear vocal pops from some consonant sounds (known as plosives). To prevent more plosive sounds and wind noise, you can use the larger A7WS windscreen.Adjust Back Panel Switches1.2.3.4.5.6.7.① Bass Rolloff Switch To reduce the bass, push the top-left switch down. This can help lower background hum from A/C, HVAC, or traffic.② Presence Boost For a brighter sound in mid-range frequencies, push the top-right switch up. This can help improve vocal clarity.③ Bypass Switch Push the bottom-left switch to the left to bypass the preamp and achieve the classic SM7B sound.④ Preamp Switch To adjust the gain on the built-in preamp, push the bottom-right switch to the left for +18 dB and to the right for +28 dB.Switching Microphone OrientationBoom and Microphone Stand Mounting ConfigurationThe SM7dB can be mounted on a boom arm or a stand. The default setup for the SM7dB is for a boom mount. To keep the rear panel facing upright when mounted on a stand, reconfigure the mounting assembly.To set up the SM7dB for a microphone stand:Remove tightening nuts on the sides.Remove the fitted washers, the lock washers, the outer brass washers, and the brass sleeves.Slide the bracket off the microphone.

耳塞的制作工艺
耳塞的材料及制作工艺耳机、耳麦可分为封闭式、开放式、半开放式。
封闭式就是通过其自带的软音垫来包裹你的耳朵，使其被完全覆盖起来。
此类耳机因为有大的音垫，所以个头也较大，但有了音垫就可以在噪音较大的环境下使用而不受影响；开放式耳机是目前比较流行的耳机样式。
此类机种的特点是通过采用海绵状的微孔发泡塑料制作透声耳垫。
它体积小巧，佩带舒适，不再是使用厚重的染音垫，也没有了与外界的隔绝感，但它的低频损失较大。
在听音方面，这款耳机还是不错的；半开放式耳机是综合了封闭式和开放式两种耳机优点的新型耳机（它是一个混血儿，融合了前两种耳机的优点，改进了不足之处），此类耳机采用了多振膜结构，除了一个主动有源振膜之外，还有多个无源从动振膜。
它不仅具有低频描述的丰满浑厚，还具有高频描述的明亮自然、层次清晰等多特点。
如今许多较高档次的耳机上广泛应用的就是这种耳机。
一只耳机主要由四个部分组成：头带、左右发声单元、耳罩和引线。
大厂家生产的耳机使用的通常是工程塑料。
头带的功能是固定左右发声单元，将其置于头的两侧，它的结构和它与单元的连接方式决定了头带和耳罩对头部的压力，影响着耳机佩带的舒适性。
耳罩是头部与发声单元接触的部件，它对于动圈式耳机是至关重要的，其功能是将低频反射回来，保证低频的重放。
耳罩一般有两种样式，一种压在耳朵上，叫压耳式耳罩(Supra-aural)，另一种耳罩呈杯状，环绕着耳朵，叫绕耳式耳罩(Circumnaural)。
耳罩要尽量的柔软舒适，其内部一般填充海绵，外面蒙上皮革或绒布。
耳罩使用的材料对中频和高频有吸收作用，它使耳朵与振膜形成一段距离，并在耳机和头部间形成一个腔室。
大型的绕耳式耳罩内部空间大，声音可以作用于耳廓，形成较好的空间感。
一只设计良好的耳机已经充分考虑了耳罩的作用，所以中高档耳机的耳罩是不可以损坏或随意更换的。
耳机的引线是耳机放大电路输出端与耳机音圈的连接线，优质耳机线常采用多支线芯的无氧铜(OFC)线，经过严格的绝缘和屏蔽处理，杜绝铜内杂质对信号传输的影响和外界杂波的干扰。
HE-R10 使用说明书
维也纳国家歌剧院前言前言HE-R10 使用说明书HE-R10 使用说明书平板耳机的复兴“我对HIFIMAN复兴平板振膜耳机给予高度评价，他们成功在Hi-End耳机市场占有一席之地，也再度激发了市场对平板耳机的热情。
边仿在耳机音质上的先进探索和努力，显然是取得了丰厚的回报。
”——知名测评人 Brent Butterworth这是平板振膜耳机的“文艺复兴”之路，也是HIFIMAN作为耳机制造商的成长史。
早期，HIFIMAN推出过一款平板耳机，型号是HE5。
起初，HE5曾使用实木来制作耳机外壳，实木是品质的象征，也奠定了HE5旗舰耳机的地位。
后来，HE5被HE5LE代替，木质外壳改为高品质ABS。
这个设计大获成功，使HE5LE成为HIFIMAN平板振膜耳机阵营的先驱。
怀着对“提高音质的新技术”的强烈好奇心与执着探索，品牌创始人边仿博士凭借纳米化学的专业学术背景，将一些理论付诸实践。
首先，他成功解决了平板振膜耳机令人诟病的重量问题，从每一个耳机部件下手，在减轻重量的同时，增加了产品强度。
HIFIMAN平板振膜耳机的优势不只体现在技术方面，更体现在对完美表达音乐内含的苛求。
多年以来，HIFIMAN推出了一系列高品质的耳机，如HE6、HE500和HE400等。
但HIFIMAN并没有自我陶醉于成就之中，而是潜心研究，推出一系列更好的产品。
从HE560、HE400i，到震撼全球发烧音响界、被誉为“世界最靓声耳机”之一的HE1000，再到高灵敏度直推型平板振膜耳机HE400S和EditionX，海内外频繁的获奖记录，无疑是对HIFIMAN团队在音质方面不懈努力的最高肯定。
2020年，HIFIMAN推出HE-R10平板振膜封闭式耳机，不止传承了独门的纳米级厚度振膜技术，更对封闭式的平板振膜技术进行了挑战。
八年磨一剑，经历无数次失败的最终调音，只为打造HE-R10这一封闭式平板振膜耳机的新旗舰。

耳机的选择一位发烧实践者的经验之谈（一）

图片没有意义。
我写的东西，大耳机是值得参考的，其次是播放器。
解码和耳放听的不多不少，买的不多不少，如果你跟我口味一样，恭喜你，你可以省钱了，但是口味不一样的不要尝试塞子，我一直拿着大耳机的指标在强人（塞子）所难，你听听看看，不要当真1854楼——1859楼，一定要看！我建议这个烧友单开一贴，我再给置顶帖链接再一次不淡定了铜涡轮1400块。
IE80的价格是1700+。
亚马逊前几天忍了又忍，还是不淡定了，买了一个铜涡轮，心急走的还是快渠道。
预计一周之后到手。
作为一个骨灰级黑魔声的初烧，看到打折，一下子崩溃了。
就跟走在路上发现商场写到打四折，一下子就不淡定了以前只是蹭听过，2800的价格说实话，实在是没办法产生兴趣。
这次是不到1400块的价格，加上运费也就是1450，勉为其难的买了吧。
你们看到这个消息，如果说缺个塞子，预算又是1500块的，我建议还是找找UE900两年保换的行货。
海淘这个东西，是没法保修的如果已经被我坑了，买了UE900，那可以考虑再被我坑一次另外，IE80价格1700+，我认为是合适的。
这个价位，很难去挑IE80的毛病了。
拿着IE80跟2800价位的几个旗舰比，我承认，我鄙视它。
但是1700+的价格，我表示，很难继续黑了看到这个信息的，手上资金宽裕，可以下手。
这两个价格是没话说的——我一直很挑剔，看了我的帖子的就知道的，如果我都觉得没话说了，肯定是值得出手的。
分篇整理分割线———————————————————————————————————————————————————————————————————————初烧大耳机篇——前言跟大耳机相关的一些东西：耳机、播放器、耳放、线、解码、音频文件、耳机线里面最重要的是什么？毫无疑问——耳机我们经常能看到一些忽悠人的说法——XX直推？不能听这个说法，大家别信，真的，坑了很多人一个耳机，如果D50直推，你喜欢，上放了肯定喜欢如果直推你不喜欢，那上了放，你也不会喜欢忽悠人的说法——直推不能听，害人在哪呢？容易让人意淫——你直推了觉得不好听，然后你意淫攒钱买了耳放就行了。
