不会, 5hz是bass, 你可以听到超超超低的低音, 不是炸出來那种, 是"听到", 所以以前我用耳机看戲, 就知道那 ...

你用什么5hz的耳机?如果用耳机那么5hz也只是震耳朵而已对吗?如果能震到整身就神了!

不会浪费的,带出门就用CUSTOM ONE PRO(带出门的粗用,坏了也不会太心疼)。
CUSTOM容易推,用 ...

COP虽然16OHM而已~但其实用手机推~我估计最多才发挥到40%实力而已~
这架还是需要AMP的。。。
不过我在等VIVO XPLAY3S~到时不用AMP再推来试试~
在家我用喇叭算咯~我对喇叭没什么要求~大声就可以了~

我的要求很简单~VIVO XPLAY3S配个AMP~配个HIFI耳机~
方便。。。。。
希望XPLAY3S DAC功能不会让我失望。。。
不然买多个DAC让我很头痛。。。。
要充电很多个==!!

它不是湿, 不会震破耳朵, 你可以"听"到那股超低音, 感覺到那低音的存在, 但不会震到你身体, 只是在脑里, 不知忘样形容, errr就拿你的湿说吧, 它可以下到低低, 換着dum心口的湿就"听"不到那股低音, 也许我说的比较誇張吧~
我不是耳机达人, 也不是用來听发燒歌, 因为工作需要, 要炸的, 粗用就可, 所以也不是很名贵的 (其実沒錢买 ) 千萬別笑小弟...
其中包括有 pionner hdj1000 (5hz-30khz), stanton dj pro 60 (3hz-28khz), AKG k81dj (16hz-24khz), aerial 7 (5hz-20khz), sony xb500(4hz-24khz)...等等, 当然也有几十块的cheap货色不便例出(当年年少無知 ), 但唯一共同点就是...... 全部都死在我手上
以下图片就是唯一的"屍骨齐全"的三只殘kicik miao:  akg (証実瓜老亲), sony(一边里面断線, 得空拿给友人动手术), stanton (做过手术不宜粗用)


在ipoh, 試机已经很難, 何况是耳机, 現在我想试听BEYERDYNAMIC, 但也怕捉虫入屎弗, 算吧喇

D Class 代表 – NuPRiME IDA-16 數碼多功兩聲道擴音機[size=0.7em]作者: 細B 3 九月 2014 NO COMMENT
玩開純音響兩聲導的發燒友都知道, 系統中越是多模擬媒體越好, 擴音機部份當然是模擬, 他們就連訊源訊號都要使用黑膠唱盤, 而這類發燒友普遍都是較資深, 或說較年長。而事實上, 我每天到J老闆中區家聽他的 Basis Debut Signature, 豐富的音樂訊息和自然醇厚的氣度, 實在靚聲到他的 CD 系統無法比美。但… 打從 CAS 開始, 數碼潮流已經入滲, 那些遠端連接 NAS 聽歌, 電腦數碼當作訊源, 甚至遙距跨國登入 Music Sever 等都很流行的了, 我們是無法途避這個數碼年代的入滲, 我相信未完全普及的數碼式擴音機, 亦將會陸續登入每個發燒友的家。


高性價比的 D 類 DAC AMP
在此之前, 我試過的數碼擴音機不多, 事實上市場亦不多款, 但今天收到的一部數碼擴音機, 無論是外觀之前衛先進, 和功能之強大, 售價之合理, 實在與傳統數碼擴音機全然不同。自從美國廠方決定整合其產品戰線,將原本清一式的NuForce品牌,現在已將高級音響類改名為 NuPRiME (主攻高階音響市場), 而新一代的繼機 NuPRiME IDA-16, 是我聽過的幾部數碼擴音機中, 性價比高得來, 音色最合我心意的一部, 論規格, 它跟本就等於一部最高數據的DAC, 因為其解讀功能是可以處理 384K 和 DSD 數碼訊號, 但就不等於它是一部只顧數碼的器材, 它除可當 DAC 功能外, 模擬輸入亦一併兼顧。如果有用戶只選用其 DAC 部份, IDA-16 亦設有 RCA 輸出, 亦即是飛起其內部的數碼擴音功能, 只當DAC使用。(#) 由於 Sony DSD 版權規限, IDA-16 的 USB 輸入, 是可以直達 384kHz, 和 DSD 的 5.6MHz, 而 S/PDIF 只可到 192KHz。
# Sony DSD 版權規限詳解
[任何一部設有 USB 輸入功能的數碼器材, 理論上由 USB 輸入的訊號是有 Jitter 抑制功能, 亦可提升 World clock 管理 (只看該機有沒有有設罝)。雖然受Sony版權限制, 任何 SACD 機都不能數位輸出, 所以限制了SACD的發展 (始終不及 CD 高級), 任何一間廠商想加強 SACD 效果增設 Digial out, 都必須採用專屬"封閉"式自家研製插頭 (不可用 SPDIF、Coaxol、XLR、Toshlink 等), 要知道想解讀 SACD  的 DAC 廠商, 絕不會為你一部機研製相同的數位輸入插頭。例如市場上就有 EMM Labs 或 Esoteric 等擁有自家 DSD 輸入輸出功能, 但就不能互相使用, 所以全數都是同一品牌的 SACD Transport 和 DAC。由於 Sony 獨攬 SACD 版權, 加上近幾年間生意大跌, 被群插下 Sony 終於開放了利用USB傳輸DSD音樂訊號, 所以近幾年間設有USB輸入的數碼器材, 都可以利用高速 USB 界面解碼 DSD。]

寧靜背景
雖然 IDA-16 的 DAC 部份是很出色, 但 IDA-16 始終都是以其強大的數碼擴音機為首。我接駁使用時給我的首個印象是 IDA-16 寧靜得出奇, 他沒有膽機的輸出牛, 沒有原子粒機的輸入繼電器, 因此我聆聽 IDA-16 時其音樂背景靜如深海, 每個錄音每首歌曲都特別清晰, 播放樂器如絃樂時, 琴音之餘韻因為 IDA-16 的寧靜而燮得非常立體通透, 琴腔殘響聲尾更長。音色感染力和絃樂獨有的木味, 物理下雖然無法與膽機相比, 但以數碼擴音機有這樣理想的絃樂音色, 已很難得。IDA-16 採用超低噪音數碼音量衰減器, 全頻分成九十九級調節, 每格 0.5dB 衰減, 比起一些前級, 雖然說九十九級不夠細節, 但以 0.5db 衰減又有不錯的分佈, 加上短距離的輸入輸出訊號, 對於 IDA-16 寧靜背景來說, 這組音量衰減器幫助很大。

出色的電容設計
IDA-16 獨家的矩陣方式排列 (CMA) 大型電容儲電備用設計, 可以讓充足的電流於瞬間供給主功率行動所需, 加上專利變頻切換開關供電 (SPMS) 技術, 令IDA-16 每聲道產生強大的 200W, 推動市場上大部份喇叭都能應付, 我曾試推動過大中細 Focus Audio FP90、Rockport Monitor、TAD S+A4SPT-VP, 都能發放出通清明快, 動力強大的音效, 當中予以樂器聲更為清徹, 型態感極佳, 當中有一次推動FP90, 播放林佳靜的《Night Stories》內李斯特的《愛之夢》, 鋼琴音色立體度像真, 氣氛和諧有質感, 音色動感與細節兼備。


細 B 沒有長時間使用數碼擴音機的經驗, 但由上星期測試至今, 我不斷嘗試循環更換 Transport 和喇叭, 發現 IDA-16 的適應性很強, 但無講我接駁的是 PS Audio Perfect Wave Transport 或 Weiss Jason Transport, 推動的是 ProAc Response D20R 或 Sonus Faber Cremna Audior Elipsa, 動態強烈, 細節清晰的特點, 我相信, 當 Run-In 得一段時間, IDA-16 相信穩定後音效將會更好。

我没玩过Audiolab 8200A。不方便发表意见

3000~5000 的Integrated Amplifier可以有很多选择。
尝试接触Audiolab以外的品牌也许会有惊喜。

如果你是在KL区。带着5000个银子和自己平时最常听的私家碟
到Sg Wang或Amcorp Mall 的音响店寻找预算内的Integrated Amplifier。
播放你的私家碟试听。把最满意的带回家。

带自己平时最常听的私家碟方便你寻找到你最满意的声音。
因为那张CD你已经听到滚瓜烂熟了。比较容易分辨好声和衰声。

如果可以的话,建议把自己的音箱也载过去。这样做可以避免“吃炸糊”
玩两声道HIFI的最高境界是要把音响的潜能完全发挥出来。
宝剑必须配绝世剑手。盲目购买Int Amp回去无法把自己的音箱完全发挥
是一个悲剧。你在音响店试听未必有卖你使用的音箱。

哗! 果然系颠佬!原来价钱平到不得了!一定要买部回家!

Trinnov Audio's "ultimate amp" supports Dolby Atmos and Auro 3-D


Trinnov Audio has launched the Altitude32 – "the ultimate AV pre-amp" – capable of decoding Auro 3-D and Dolby Atmos, provided you've got the necessary £26,900.

The Altitude32 is clearly geared towards professional environments - or particularly discerning customers - but shows the increasing support for Dolby Atmos across the wider AV industry and, as Trinnov Audio modestly states, paves the way for "a whole new generation of luxury home cinema processors... driven by 3D Audio, 4K and HDMI 2.0."
As the name suggests, the Altitude32 has an impressive 32 discrete channels on board (Dolby Atmos can support up to 34) and, provided you pay an extra £1950 for the 3D Audio package (!), can decode both Atmos and the similar Auro 3-D format

Without the 3D upgrade, it supports the more commonplace Dolby Digital Plus, Dolby TrueHD, DTS Digital Surround and DTS-HD Master Audio codecs. The processor also supports high-res WAV and FLAC files up to 24-bit/192kHz, too.
The pre-amp’s processing is driven by a single, multi-core Intel processor, and claims to be future-proof thanks to the ease of releasing software upgrades.
The Altitude32 also pioneers the French company's own patented 3D mapping and room optimization technology, which claims to enhance performance according to a specific room’s shape using the company’s £550 3D Measurement Probe (microphone to me and you).


It’s not surprising that a product of this spec isn’t shy of connections. Of its "118 digital and analogue inputs", there are eight HDMI, four optical and four coaxial digital inputs, as well as 16 balanced analogue inputs. As for its "80 audio outputs", digital outputs include two HDMIs and one coaxial and optical apiece, while 32 are balanced analogue outputs.
There’s built-in wi-fi and a web-interface display. Its aluminum casing comes in a black or light grey finish as standard, with a silver finish available... for a £650 premium.
Beneath this top-ranging model are three other versions with 8, 16 or 24 channels and fewer connections, the most stripped down available for £14,950. Other products in the range include the Magnitude32 multi-channel processor and Amethyst hi-fi pre-amplifier

Auro Technologies - Mensa AV Processor

         

Auro Technologies New Mensa Processor Will Include Both Dolby Atmos and Auro-3D Processing

The lure of Dolby Atmos is global, people! Belgium-based manufacturer Auro Technologies has announced plans to put Dolby Atmos into its new flagship AV processor, the Auro-3D Mensa.
Dolby Atmos is an audio format that can reproduce sound from just about every direction, including overhead. Although it was previously limited to select movie theaters, Dolby is now bringing the format to home theater equipment. That way, you can actually have it sound like helicopters or birds are flying above your living room.
Just in case you need to be completely wrapped in sound at all times, the Auro-3D Mensa will also have the Auro-3D format. In other words, there's a lot of immersive audio under that single chassis! According to the company, Auro-3D Mensa owners can enjoy multiple speaker configurations up to Auro 13.1, with immersive 3D sound capabilities. It also has the Auro-Codec Decoder for playback of native Auro-3D content, while the Auro-Matic upmixing algorithm makes it possible to upmix 2.0, 5.1 or 7.1 soundtracks into the Auro-3D format.




Created in conjunction with Datasat Digital Entertainment, the Auro-3D Mensa promises stunning audio via 16 output channels. Other features include Dirac Live room optimization, memory profile settings, stackable multiple EQs, room optimization/correction and automation controls.
"The Auro-3D Mensa features Auro-3D, and will also support Dolby Atmos. The Auro-3D Mensa is a high-quality, feature-rich, versatile and customizable audio processor that delivers a movie and music experience unlike anything you've ever heard before," said company founder, Wilfried Van Baelen. "We are sure that you'll be blown away by it!"
The company says that additional products packing both Auro-3D and Dolby Atmos will be released in the near future. In fact, Trinnov just debuted the Trinnov Altitude32 32-channel preamp, with Datasat announcing the same for the company's RS20i digital audio processor.

甲类的20W比甲乙类20W更强劲吗?

接理说,驱动能力跟放大器的电路形式没有关系,只应该和机器的输出功率有关,
“甲类的20W比甲乙类20W更强劲”这种说法是没有根据的。
放大器的输出功率有一个国际上普遍遵守的测试标准:通常是输入1KHz的正弦波信号,
在放大器的输出端接上8Ω的纯电阻负载,然后逐渐开大音量,
并用失真度测试仪监视输出端的失真情况。随着输出功率增加,失真度也开始加大,
当失真度达到一个预设标准时(例如1%),停止加大音量,然后测出此时输出端的电压值,
根据欧姆定律再换算成功率,此功率就是放大器的额定输出功率,也叫RMS功率。由此可见,
测得的输出功率本身就是最终结果,与机器的内部结构没有任何关系,不论哪种工作状态的机器,
不管它重几斤几两,也不管它是胆机还是晶体管机,20W就是20W,只要输出功率一样,
驱动能力也就不应该有区别。

然而,不少人的实际听感都表明:很多时候同等功率的纯甲类功放就是感觉更有力一些。
如何解释这种现象呢?其实人们的听感没有错,
但造成这一现象的原因却不是因为采用了纯甲类放大的缘故,
而是因为纯甲类功放的电源供应通常更为充沛,这才是导致听感更有力的真正原因。

原来,纯甲类功放的效率很低,算上各种损耗,平均效率只有30%左右。
这样,一台20W的功放,就得配备65W以上的电源部分,双声道就是130W。
而甲乙类功放的效率相当高,通常有60%以上,同样20W输出的甲乙类功放,
配40W以上的电源就够了,双声道80W。实际上,出于成本的考虑,
20W甲乙类功放的电源部分往往还没有80W,可能也就40—50W左右,
因为甲乙类功放的耗电基本上是随着输出功率的增长而加大的,你不可能开到满功率输出来听音乐,
所以一般不会耗尽80W的电源功率。但纯甲类功放不能这么干,为什么?
甲类功放在没有信号输入时耗电就达到最大值,
换句话说,20W的纯甲类功放肯定会用尽130W的电源功率,一点折扣都不能打。

现在您看到区别了,同样20W的功放,纯甲类机器的电源有130W,
甲乙类只有40—50W,相差了3倍左右。这三倍的电源供应之差会导致什么结果呢?
比如喇叭阻抗随频率的变化下降了一倍(这种情况很常见),甲类功放因为有充沛的电源供应,
瞬时输出功率可能成比例增长一倍(即所谓的大电流功放),
而甲乙类功放一般做不到,从而导致“脚软”的现象。由此可见,
普通甲乙类功放在电源供应上的节省,才是导致其听感不如甲类功放有力的真正原因。
高档的甲乙类机在民源设计上不惜成本,功率余量超过实际需要很多,
此时不会再出现驱动力不及同功率纯甲类机的现象。


注意其中几处错误
1. “也不管它是胆机还是晶体管机,20W就是20W,只要输出功率一样,驱动能力也就不应该有区别。
    ”这句话是错误的,驱动能力还和其它因素有关,比如阻尼系数等

2. “纯甲类功放的效率很低,算上各种损耗,平均效率只有30%左右。
    ”也是错误的,甲类最高效率不会超过25%,而且是理论上的最高值

鬼佬呢排好長進喎﹗唔錯唔錯~ 又多部Auro-3D前級﹗

Full Immersion: Auro-3D Auriga Home Theater Receiver
          By Bob Ankosko • Posted: Sep 5, 2014                  
              
      


    Note to readers: See Clarification at the end of this article for an update.Weeks before Onkyo and Pioneer announced the first Dolby Atmos-equipped AV receivers, we received a press release touting the “first ever immersive sound receiver”—the Auro-3D Auriga from Belgium-based Auro Technlogies. Intrigued by its high-end looks—and $16,700 price—we reached out to CEO and Auro-3D inventor Wilfried Van Baelen to learn more about the product and the Auro 3D surround-sound format at its core. Auro 11.1, which adds height and overhead channels to an existing 5.1 surround-sound setup, debuted in theaters in 2011 and today supports almost 500 screens worldwide, according to the company. Recent movies mixed in Auro 11.1 include Oculus, The Amazing Spider-Man 2, How to Train Your Dragon 2, and a number of foreign films.


S&V: Tell us about Auro-3D.

Wilfried Van Baelen: Auro-3D is the next generation three-dimensional audio standard. The format is designed as a “one cross-market solution” for movies, games, broadcast, and music. By fully immersing the listener in a cocoon of life-like sound, Auro-3D creates the sensation of “being there” by adding a very specific ingredient to the sonic mix: height, the crucial third and final dimension in the evolution of sound reproduction.


S&V: How does Auro-3D differ from Dolby Atmos?

WVB: There are many differences. The only thing we have in common is that we add height to the existing surround format. Immersive sound is all about the vertical spread of sound in a hemisphere around the audience, so the speaker layout is crucial. Dolby Atmos has two vertical layers while Auro-3D has three vertical layers around the audience to achieve a more natural spread of sound energy and more precise location of sources and their reflections in the vertical axis, starting from ear level to the top. What is unique to Auro-3D is the vertical stereo field of 30 degrees in front of and around the listener, which creates a more natural reproduction of the sound sources and their 3D reflections compared with our competitor’s format.

Another major difference is that Auro-3D is based on high-resolution audio (PCM) in each channel, while Dolby Atmos uses the [new] AC-4 lossy codec (successor to AC-3). Additionally, to achieve the precision of object based technology like Dolby Atmos, you need more amplified channels. I wonder if people are really going to install a true 3D speaker layout to listen to a lossy quality of sound like AC-4. Having PCM sound quality is very important for true 3D sound—lossy codecs delete spatial information that is crucial for our subconscious brain to achieve a true 3D sound experience. Our technology also allows you to use your existing Blu-ray player without the need for any upgrade. These are just a few differences but there are many more.


S&V: What’s special about the Auriga AV receiver?

WVB: The Auriga is the world’s first integrated 3D sound processor for consumers. It’s a state-of-the-art device that has multiple HMDI inputs, 16 output channels—13 of which are powered by high quality 200-watt amplifiers—and it’s upgradeable to 4K. 3D processing is handled by the Auro-3D Engine, which automatically recognizes whether an Auro-encoded track is present or not. When it is, the Auro-Codec Decoder reproduces it from that Auro-encoded standard 5.1 PCM track as it was intended by its creators without any audible loss in the sound quality. Auro encoding is contained in the same file as the standard 5.1 PCM surround master on the Blu-ray disc.
If there is no metadata, the Engine will recognize which legacy format is present (mono, stereo or 5.1/7.1 surround) and send that signal through the Auro-Matic algorithm, which enhances the emotional connection and brings the audience subconsciously closer to the soul of the artist or to the action on screen. That means you can enjoy Auro-3D with everything you are listening to or watching because it creates a life-like envelopment of sound that can only be reached by adding height speakers as defined by the Auro-3D format.


S&V: Why Auriga?
WVB: I was always intrigued by the magic of the universe. I had already named my company Galaxy Studios in 1982 and I wanted to bring the names of star constellations to our devices because they are based on an audio format representing the three-dimensional space around us. Auriga is a special star constellation and I chose that name for the first AV receiver with true 3D Sound capabilities.

S&V: Can you run through the possible channel/speaker layouts?

WVB: Auro-3D has scalable true 3D sound formats for different size rooms. For a smaller home cinema, Auro 9.1 is the most efficient system with height channels in front and around the listener, and it is backward compatible with 5.1. This compatibility is the basic idea behind all Auro-3D formats. Having that “vertical stereo field” between ear-level and Auro-3D’s unique height layer all around the listener creates the most immersive experience.

For larger rooms, we add a center height channel and a top (overhead) layer directly above the listeners, which results in Auro 11.1. I designed this format especially for the theatrical world and it has been embraced by our partner Barco, the worldwide leader in digital cinema projectors. The Auro 13.1 format is the same but based on an existing 7.1 surround system.
Another difference with Dolby Atmos is that our speaker layout in theaters is based on the existing 5.1 and 7.1 surround standards while Dolby Atmos is not. The distance between speakers is smaller and they are all directed to a reference position in the room, which creates more clustering and phasing effects. Last but not least, Dolby Atmos surround speakers are elevated more than the 5.1 or 7.1 surround standard, which doesn’t allow vertical precision of ear-level sounds, which is where most sounds in nature occur. This is not the case with the Auro-3D, which can playback the 5.1 and 7.1 tracks as defined by the standards used in theaters worldwide as well the ITU standard for home applications.


S&V: How many Auro-3D movies on Blu-ray do you anticipate by the end of 2014?

WVB: The number of Auro-3D films coming out on Blu-ray before the end of the year is not yet defined but it will be an impressive list. The consumer market is also now demanding more titles, which will help bring more Auro-3D movies to the home market.
But Auro-3D is not only about films—music is very important as well. Auro-3D is a mixing format as well as a native recording format, which Dolby Atmos is not. We have developed a range of professional audio production tools and are working closely with the industry to release music titles. Several labels will announce Auro-3D content within the next few weeks. Blu-ray is an ideal format for high-resolution audio encoded in Auro-3D.


S&V: Will Auriga be available in U.S. retail stores?

WVB: We are currently in the process of executing agreements with U.S. distribution chains to bring the Auriga into people’s homes. Right now, you can order directly through Auro Technologies or email us at [url=mailto:%20sales@auro-technologies.com]sales@auro-technologies.com[/url].

Clarification: After our publication of this story online and in the October issue of Sound & Vision magazine, Dolby Labs contacted us to clarify what they saw as inaccurate statements by the interviewee in his description of its Atmos technology. The company supplied the following information:


  • Dolby Atmos is currently supported for Blu-ray through the Dolby TrueHD codec, a lossless format that is equivalent to uncompressed PCM sound quality upon playback. The lossy codec Dolby Digital Plus supports Atmos for streaming and broadcast applications, and has been updated to carry Atmos soundtracks without compromising spatial information.
  • Existing Blu-ray players meeting current Blu-ray specifications can pass the Dolby Atmos bitstream with no upgrades required, though Dolby always recommends updating to the manufacturer’s latest firmware.
  • The channel-based bed component of Dolby Atmos as used in theaters is based on the standard 7.1 surround configuration.
