Resonessence Labs是近來非常火紅的牌子，臺灣也終於有代理引進
其主要設計者都是DAC與ADC的專家，是ESS的中心人物，也難怪第一個推出的Invicta就能引起注目
這次試聽的正是Invicta，就由一樣火紅的Brown熊大揭開序幕吧

彩色的說明書，官網也能下載
http://www.my-hiend.com/leoyeh2/2013a/IMG_8990ss.jpg
體積不大，中間為顯示螢幕，左方有兩個耳機輸出，右方為取樣頻率顯示，控制按紐
左方的DXD與DSD宣告了最高的規格解碼能力
特別的是可以看到有一個記憶卡插槽，Invicta可以直接解碼記憶卡中的音樂檔案
http://www.my-hiend.com/leoyeh2/2013a/IMG_8994ss.jpg
背後的端子非常齊全，包括平衡類比輸出，各式數位輸入，SYNC應該是時鐘接口，還有一個HDMI可以接到螢幕顯示...對於要使用大螢幕控制顯示的數位玩家很是方便
http://www.my-hiend.com/leoyeh2/2013a/IMG_8998ss.jpg
更精彩的當然就是要看看內在美了
http://www.my-hiend.com/leoyeh2/2013a/IMG_9002ss.jpg
先來一張內部全圖，超級有料
http://www.my-hiend.com/leoyeh2/2013a/IMG_9003ss.jpg
期待更深入的评测，看到支持双D(DSD、DXD)就更期待了
小而豐滿的內在真是讓人興奮
遠遠就看到那個ESS晶片，這麼小的體積，以DAC來說，這顆環型變壓器超出誠意了
內部各個部份都有隔離區分，井然有序
仔細看，ESS那個解碼中心有下上兩層線路喔
Invicta共使用了兩顆32 Bits ESS Sabre晶片
原廠56頁的技術說明，嗯............晚點來看

接上後發現不知道怎麼開機，原來盒子內下方還有一層，有擺了遙控器與配件
http://www.my-hiend.com/leoyeh2/2013a/IMG_9052ss.jpg
驚！使用的是Apple Remote，跟之前的Alluxity一樣
http://www.my-hiend.com/leoyeh2/2013a/IMG_9053ss.jpg
待機左方的Logo是紅色的，開機後就會變成藍色

Incivta的解碼輸入有很多種，我是先用USB

Invicta有一個非常特別的功能，就是前方有個SD的記憶卡插槽，可直接讀取SD卡裡的音樂檔案，一樣可支援到DSD 5.6MHz與DXD
因此今天主要就是測試這個部份，把要聽的音樂檔先拷貝到SD卡中
http://www.my-hiend.com/leoyeh2/2014a/IMG_9777ss.jpg
特地挑了DSD 5.6, DSD 2.8, RR 176.4(WAV與AIFF), 還有MP3
http://www.my-hiend.com/leoyeh2/2014a/daily001514.jpg
從前方放入即可
http://www.my-hiend.com/leoyeh2/2014a/IMG_9782ss.jpg
輸入要切換到SD Card Audio
http://www.my-hiend.com/leoyeh2/2014a/IMG_9786ss.jpg
直接就可看到各個子目錄
http://www.my-hiend.com/leoyeh2/2014a/IMG_9788ss.jpg
DSD 5.6，第2排的燈就會亮起
http://www.my-hiend.com/leoyeh2/2014a/IMG_9789ss.jpg
DXD, 352.8kHz
http://www.my-hiend.com/leoyeh2/2014a/IMG_9793ss.jpg
DSD 2.8，第一排燈亮起，右下也會顯示DSD
http://www.my-hiend.com/leoyeh2/2014a/IMG_9794ss.jpg
WAV與AIFF都可，但MP3，很抱歉，太Low End，沒支援！
另外也試聽了耳擴的部份，共有兩組，尚未看這兩組有無不同
先接再第一組，兩組都有單獨的開關，不用可以關上，藍燈是指示燈
推Sennheiser的HD 800，沒想到效果相當好，推力足夠，各頻段包括音場都有推開，很是厲害
若要吹毛求疵，就是低頻的量少了一點點

這台DAC體機不大, 比一張A4紙還要小, 但是昨天聽了一陣子發覺蠻不簡單的,
雖然有一陣子沒有在試音室好好聽音樂了, 但是昨天搭配的器材以及試音室的ㄧ些特性基本上都是熟悉的, 相對陌生的是這台DAC, 昨天聽得多半44.1KHz, 由CD Rip過去的音樂, 整體來說, 聲音開闊, 音像井然有序, 整體感很好
高端的延伸很完整, 聲音散得很開, 解析很好, 發聲點穩穩地控制在該有的地方, 不前傾, 不會過於刺激
昨天還特地利用相同的曲目, 以這台DAC為中心, 比較USB (Mac mini) 以及 透過轉盤 (Teac PD501)的差異, 比試之前其實我自己知前的經驗已經心有偏見, 認為應該是轉盤勝利, 但是幾首曲子ABA比較後, 我發現差異真的小的可以, 硬要說, 我當然還是私心認為轉盤好上ㄧ些, 但是其差異真的是非常非常小,
當然對於電路這些我是不懂, 但是這樣的結果告訴我的是, 這台DAC有對於USB訊號的隔離下了比其他DAC更多的功夫, 讓電腦 + USB這種電氣很糟糕的環境能夠與轉盤這種相對單純的環境一較高下!
總得來說, 這應是一台以中性為訴求的DAC, 聆聽的過程, 我聽到更多勞倫斯喇叭, Onix前後級的聲音, 我想, 如果我能聽到更多喇叭與擴大機的聲音, 應該就代表這台DAC自己的聲音比較小了吧! 哈哈! 以最前端的器材來說, 這是好的, 也是更為耐用的, 把搭配的事情交由後面的器材, 前端好好扮演好還原的角色.
聆聽的時間不多, 但是這台DAC已經留給我很好的印象!
Invicta的功能實在非常強大，越是接觸把玩，越是覺得他的厲害
就像這個數位音控，居然最低可以到-127.5dB
http://www.my-hiend.com/leoyeh2/2014a/IMG_9962ss.jpg
這是以另外一台CD為轉盤，利用Invicta的SPDIF(BNC)進行解碼試聽
由於手邊沒有BNC的數位線，用了一個RCA/BNC轉接頭
http://www.my-hiend.com/leoyeh2/2014a/IMG_9964ss.jpg
强烈关注这台DAC，特别关心其SD卡的播放效果，因为玩的时间长了后还是希望归于简单，目前看来直接读取SD卡这种方式最为简单，所以还请叶大详细谈谈SD卡的播放效果如何？相对比连接电脑的差别在何处？
SD效果目前聽起來就是比較好 背景更黑 音質更純淨 也能支援到DSD128
您的意思是，SD卡一样可以解码：DSD 128, DXD, PCM 384吗（SD卡功能与其他接口一致）？
还弱弱的问一句， Invicta 直解DSD码？还是PCM转码？
yes SD 可
ES9018可直接解DSD
再请教一下叶大，在使用SD卡播放时，能否用 智能手机遥控音量和选曲？
如果可以，一对主动式喇叭加上一部Invicta和智能手机，就全搞定啦！
iphone或是ipad可能可以，因為他的遙控器是apple remote
有機會我研究看看
Invicta內部的數位濾波高達7種，是我目前試聽過最多種的 (當然有其他DAC可能有更多種)
用家可玩性非常高
其實Invicta的設定蠻多的，但都很直覺與方便，且都是具有意義與功能性的

Up-sampling Filters in the INVICTA rev 3.0 Software
• The internal Fast Roll-off filter pre-installed in the Sabre DAC.
On the OLED display panel this appears as “Sabre Fast Roll-Off” This is a ‘classic’ FIR filter with symmetrical coefficients, hence it is linear phase and nondispersive.
It achieves excellent suppression of -115db, and so has to have a relatively large group delay of 35 samples. That means, that for a CD at 44.1Khz the group delay is about 800uS. (less for higher sample rates). This filter exhibits pre-ringing, but achieves perfection in rejection: no sample rate artifacts above 22.05Khz are present in the output.
• The internal Slow Roll-off filter pre-installed in the Sabre DAC.
On the OLED display panel this appears as “Sabre Slow Roll-Off” This filter is designed to reduce the group delay present in the Fast Roll-off filter. It is a symmetrical impulse response (i.e. it has symmetrical coefficients), it is linear phase and non-dispersive. It achieves good rejection but the rejection begins slowly, 24Khz or so is
present in the output if the music content has signals near 20khz, but signals higher than that are suppressed. The group delay however is much less, being only 6.25 samples or 140uS at 44.1Khz. This filter also exhibits pre-ringing.
• Resonessence designed, Minimum Phase, IIR Filter
On the OLED display panel this appears as “Minimum Phase IIR” This filter is designed from an analog filter prototype and exhibits no pre-ringing at all. To achieve this, it has to compromise the steepness of the filter; it corresponds to a fourth order analog filter. This is a dispersive non-linear phase filter, but the dispersion has been optimized to the absolute minimum consistent with no pre-ringing.
• Resonessence designed, Minimum Phase Slow Roll-off.
On the OLED display panel this appears as “Minimum Phase Slow Roll-Off” This is a FIR filter that exceeds the specification of the above IIR filter achieving -100db stop band. It is not a linear phase filter because it has non-symmetric coefficients but has been designed to exhibit virtually no pre-ringing (but it does have some) with the minimum of dispersion.
• Resonessence designed, Linear Phase Apodizing Filter.
On the OLED display panel this appears as “Linear Phase Apodizing” Perfectly symmetrical impulse response, hence linear phase and non-dispersive, this filter achieves a high -96db rejection at fs/2 and exhibits the minimum of pre-ringing possible while achieving this excellent rejection. This is the preferred filter of many of our beta-testers.
• Resonessence designed, Linear Phase Fast Roll-off
On the OLED display panel this appears as “Linear Phase Fast Roll-Off” The ultimate FIR filter in the ‘classic’ linear phase category. This filter delivers ultra-high suppression of -120db and extreme flatness in the band. It exceeds the performance of the Sabre DAC pre-installed Fast Roll-off filter.
• Resonessence designed, Linear Phase Slow Roll-off
On the OLED display panel this appears as “Linear Phase Slow Roll-Off” Designed as an enhanced version of the preinstalled Sabre DAC Slow-roll off filter, this is a
linear phase, hence non-dispersive, low group delay filter that has less ripple in band and higher rejection that the Sabre Slow Roll-off filter
再请问叶大，SD卡模式可否直接播放SACD ISO文件？
只能dsf或dff....
小葉站長有試過iPhone或iPad能否操控他了嗎？引用:

Remote 用的是紅外線
iPad 沒紅外線
所以不行
那顆變壓器看起來怎麼感覺像中製或台製的阿?
挖!查了一下真的是中國出品!!!!
