No op-amp, no feedback loop

Even the most sophisticated op-amp relies on feedback action. That’s the nature of any op-amp. Years ago we found out, that loop feedback has a bad influence on sound, so we constructed our circuits without that emergency measure. Sorry, op-amp are not an option for us, although discrete circuits costs more, consume more power and inhabit more board space.

Asynchronous USB transceiver

any form of jitter in the incoming data stream is compensated by a small buffer. The audio data is clocked out by a local high precision quartz master clock. With this operation mode, the DAC is the master, whereas the computer is the slave. Timing errors are effectively eliminated.


The asynchronous USB mode not only plays an important role in handling PCM signal, it is even more so for DSD signal, as re-clocking of DSD signal is not applicable.


USB數據非同步傳輸, 差不多是公認而有效減低時差low jitter的方式 ; 更重要的, DSD數據本位支持, 即沒把原有DSD數據轉換成PCM, 當中亦不可能作任何re-clocking時基重組... 這是最理想和最直接的DSD數據處理模式, 需要配合格外精準之時基主控。
ARIOSO內置極高精度主時鐘, 誤差只是3 ps, 即佰萬份之三秒, 規格明顯比市場上其他同價位產品更具優勢。

DSD support

DSD64 and DSD128 are supported natively. A direct signal path between the USB transceiver and the DAC chip modulator leaves out the digital interpolator stage common in PCM processing.


DSD數據本位支持, 從usb輸入直通解碼部份, 中間無須經過PCM轉換, 減免了當中的interpolation [挿值]誤差。

找機會把兩者公平對比一下....

Arioso耳擴部份

初步開聲, 首先打算測試一下它耳機驅動部份有多少斤両, 是否隨意奉送, 跟市場上幾仟元耳擴產品怎樣比較 ? 既然Airoso全新機器已不停煲練了幾天, 那麼便粗略地比試一下...

OK 二話不說, 利用Linnenberg 自家的cdp-3e CD機 :
音頻輸出以xlr信號線連接上Violectric V100 ;
同時利用 vdH DIGI-COUPLER 75 Ohm同軸數碼線 把Arioso連接到cdp-3E數碼輸出。

熱機大半個小時, 接上Beyer T1, 隨手放上一張Eric Clapton “one more car one more rider” 現場錄音 ....

第一印象, 兩者的推力沒感覺到有明顯分野, 基於600 Ohm T1需求足夠電壓擺幅來推動的情況下, 初步估計Arioso應有條件對付高阻耳機。

跟著慢慢反覆比較V100, 有以下發現 :

1. 不難察覺, V100聲音少了些靈活和敏捷感覺, 尤其中低音段收放反應未夠利落, 變速帶點遲鈍...

明顯程度視乎曲目要求和錄音水平, 這CD出自樂界知名母帶工程師Bob Ludwig, 音响迷的大師級人馬, 音效水平無容置疑, 亦難到很多平庸hifi組合。
這CD裡面收錄了大量繁複又強烈的電子合成低音聲樂, 和採用動態擴展dynamic expander的鼓組 (大家可以想像得到這類大型戶外巡迴演唱營造出的宏大聲响效果) , 若然含糊攪作一團的話 實在沒甚好聽。

2. 用音箱來比喻, 類似低頻注波未能及時消散, 並干擾至中/高頻段清晰度, 令到整體聲音畫面帶點混濁, 起動和爬升都有些少笨重感覺

3. 人聲和樂器發聲線條較粗, Eric Clapton吉他最明顯, 每首曲目每枝吉他都好像配上了粗魚絲或粗鋼線彈奏, 加上聲音起落幅度沒做到很廣闊, 容易給人錯覺, 以為[高密度]和[聲音豐滿]

4. 的確, Violectric高頻段範圍內之訊噪比水平較為弱勢, 至使高音聽感始終未算開揚明朗, 空間透視不足, V100亦不例外。 但點評必須公道, 事實上很多產品也同樣出現這毛病, 高頻訊噪比並不優秀, 妨礙了錄音內極之真貴的空間透視信息, 造成聲場空間較暗欠缺光亮度, 亦掩蓋了樂器應有的玲瓏光澤, 只不過分別在於是否容易顯露出來而已

換上V200試試, 同樣地利用xlr信號線接往cdp-3E音頻輸出。

相比V100, V200信息明顯增多了, 畢竟cdp-3E價格為4,800歐羅, 檔次絕對不低, 宜選用非入門級別組合才有機會反映這高質信源和錄音真正水平。

首先, 頻寬方面bandwidth我覺得V100 / V200兩者無明顯分別, 然而V200的能量就的確比V100增大了尺碼。

可惜當應付mid-high region(中高區域) 複雜又緊湊之強音時, V200似乎有點消化不來 ; Eric Clapton吉他能清楚反映 : 強聲彈奏出現渾濁和拉緊狀態, 打個比喻來形容, 好像演台上guitar amp overload吉他音箱超負荷, 過荷過熱耗散不來令聲音粗啞擠壓, 弦線尾聲短鈍, 泛音散射不開。這很考驗'中高區域'之瞬變反應mid-high transient response, 重播吉他, 琵琶這類樂器容易暴露出毛病。

與Arioso相比, V200鼓擊之激烈程度(snap)没那麼狠辣明快, 力度變化都少了花樣, 節奏起伏略嫌平淡。Eric Clapton當然是殿堂級數, 相信參與本次巡迴演唱的各方樂手也不會是平庸之輩, 此錄音當中不難感受到樂手們非常雀躍地落力演奏, 氣氛熱烈, 這方面Arioso反映得相當傳神, 值得稱讚。

另外, V200低音段傾向濃而圓厚, 之不過針對繁複低音的分解能力和瞬變反應未能乾淨利落, 線條未算清晰明朗。是的, 低頻余音滯留時間確實比較長, 聽感上底盤沈厚, 適宜匹配AKG 701/702 這類低音線條纤细的耳機。
