最近陪朋友去試一部ARC REF. 75後級, 此後級只係得75w per channel, 每邊行兩支KT120 POWER TUBE. 試聽推動WILSON AUDIO SASHA. 唔聽尤自可, 一聽就"O"晒咀.
每邊75W輸出既膽後級, 在二百多尺既環境下, 其推動力及控制力竟可令對SASHA貼貼服服!
這次試機經驗, 令我對KT120這款新膽有著十分高既評價!
過兩日, 收到新漢通知, 會SEND部OCTAVE V110合併比我測試. 唉! 我對屏風係大食怪, 一部合併機仔, 推屏風有無聲出都成問題啦.
但當我知道依部V110係用四支KT120做功率管後, 立即雙眼發光. 
用四支KT120究竟推唔推到我對屏風呢? 我自己都好想知.
新漢易十分貼心地為我著想, 送多部METRONOME CD8s比我夾OCTAVE V110, 順便可以比併一下!
開箱既OCTAVE V110, 使用三層紙皮盒, 再加上兩個盒仔用黎裝住D大膽細膽, 十分安全.
先copy番V110官網既簡介先.
The Octave V 110 integrated amplifier is a push-pull pentode design delivering 2 x 110 W RMS output power (into 4 ohm loads). As with all Octave models, all research and development (R&D) and production has been conducted exclusively in-house, and the amplifier is comprehensively safeguarded against user error and parts wear – including catastrophic power tube failure.
The V 110 is a new member of KT 120 based amplifiers containing our proprietary Amplifier Technology. Ultra Low Noise and precise regulated Power Supply voltages ensure stable operation independent of mains fluctuations and high frequency noise distortions of the mains voltage. The V 110 improves upon the V 70 SE predecessor, with upgrades made in the amplification stages as well as the power supply. Ultra-low leakage Tantalum electrolytic caps are now used instead of Aluminum electrolytic caps in the driver circuit.
The heater voltage of the driver tubes has been precisely stabilized to reduce hum and noise that would otherwise be caused by the heater system. The heater and the supply voltage are both controlled via the power management circuit. The stabilization of the heater and power supply voltages ensures the stable, drift free operation in the mains range of +/- 15%. Every output tube in the V 110 is protected against over-current and other tube problems caused by aging.

部V110既外型與之前既合併都係差唔多樣, 我最欣賞佢既面罩設計, 又夠實用, 又夠晒有型. 因為我屋企有小朋友, 佢有時會喺屋企玩踢波, 如果部膽機無[保護罩]既話, 套膽一定頂唔到一個星期就被[撃]破. 哈哈.
全機既牛牛放置在機尾部份, 前面就用來插膽, 四支KT120功率膽就係插喺前面, 當然再前D有三支膽仔, 12AX7 & 12AU7.
訊號輸入方面, 有四組RCA & 一組XLR INPUT, 其中一組RCA輸入是BYPASS.
根據說明書所講, 機背後有粒制, 可調較輸出功率, 70W / 110W. 當使用跟機既KT120時, 輸出功率可調至110W. 如想轉吓口味, 用使用6550 / KT88等等既膽使用在V110上, 咁就要將輸出功率調較至70W. (之後會作詳細測試依個功能對音色音質上既改變)
當然, 仲有個BLACK BOX接口, 比用家可以選擇性升級電源BLACK BOX 或更高型號既SUPER BLACK BOX. (聽聞加左BLACK BOX後, 其控制力會有明顯提升! , 最衰今次無得試啦 )
我測試器材有個習慣, 駁好晒線後, 開聲煲機, 一路煲機, 一路攞佢本說明書出黎, 直至睇晒本說明書, 才開始認真咁測試.
今次用黎測試既CDP, 就係我用緊要耐既AUDIO RESEARCH CD8, 我成日都同網友講, 在這個range內, 最全面既CDP, 一定係ARC CD8.
當然, ARC CD8既OUTLOOK又唔係咁多人接受到, 佢地大都會反問, 咁METRONOME CD8s呢? 邊部好D? 兩部都差唔多價位喎.
果陣時因為我未聽過METRONOME CD8s, 所以NO COMMENT.
但今次唔同了, 我打算用OCTAVE既合併機V110做膽, 試埋ARC VS METRONOME既CD8s.
再介紹埋Metronome CD8s先,

外觀上, METRONOME CD8S真係靚仔, 就算我係ARC FANS都好, 我都係覺得METRONOME既CD8S靚仔過ARC CD8好多好多. 尤其係佢果三隻釘腳, 真係靚到爆.
開左個CD 蓋, 又有藍色LED, 加添了現代感. 
仲有部METRONOME CD8有得玩CAS, 得USB輸入, 的確比ARC CD8更多樣化.
唯一美中不足係佢果[膠remote], 好鬼簡陋.
今次既REPORT首先測試OCTAVE V110合併機, 在我屋企230尺既聆聽環境中, 夠唔夠力推動我對屏風3.7.
使用器材及材線:
AUDIO RESEARCH CD8 使用 SHUNYATA ZITRON COBRA PC, 平衡線就使用CARDAS CLEAR XLR,
OCTAVE V110, PC使用SHUNYATA ZITRON COBRA,
MAGNEPAN 3.7 使用TRANSPARENT ULTRA SPEAKER CABLE.
當然, 為左有更多線材配搭, PC仲有NORDOST VALHALLA, XLR仲有NORDOST VALKYRIA.
測試軟件就用2004 LPCD.
首先試左套ARC CD8 + OCTAVE V110先, 聽左兩首就覺得唔對路, 音質好薄好薄, 密度嚴重不足. 尤其係播小品人聽, 好鬼難聽, 大聲小小, 仲有小小燥添.
之後我立即將對CARDAS CLEAR改走, 換用NORDOST VALKYRIA 上陣, 密度不足依然嚴重, 但已順耳好多. 之後再換PC去NORDOST VALHALLA, 再幼細D, 但動態又有少少不足. 睇黎ARC CD8唔係太夾OCTAVE V110喎.
咁唯有試下用METRONOME CD8夾OCTAVE V110, 聽左兩首小品, EEE...正路番喎, 有高有低, 密度好高. 咁算啦, ARC唔夾OCTAVE, 無唯勉強!
咁我就可以專心咁測試METRONOME CD8 + OCTAVE V110既實力啦.
OCTAVE既器材, 一向以動態見稱, 所以首先以一首古典來測試佢既速度及控制力, 第10首既RIMSKY KORSAKOV. SCHEHERAZADE, OP35就正正能反映到V110既優點, 背景寧靜, 高速既瞬變, 超強動態, 往往能輕易帶領聆聽者進入歌曲既意境.
開頭既小提琴當去到大爆棚既時侯, 佢既瞬變比我用開既ARC+PASS更快, 抽上去既速度真係好爽, 低頻量感及質感, 竟然比我用開既PASSLABS XA100.5更實淨.
聽完首古典, 當然唔少得播埋第十二首既牛鬥虎, 有無攪錯, 低頻力感比PASSLABS XA100.5更好. 鼓皮震動既餘韻, 每一下鼓聲既力度表達得超乎想像咁好. 依D就係所謂既低頻分析力. KT120真係好堅.
試完D大動態曲目, 當然唔少得人聲小品啦, 講真, OCTAVE一向給我既感覺是快, 偏冷, 中頻人聲我不存任何冀望. 就算加上METRONOME CD8, 人聲既感染力應該毒唔到我.
但當JHEENA LODWICK開聲果時, 我有少少跌眼鏡既感覺, METRONOME果然係CDP既專家, 竟然可以令V110推屏風, 都出到應有既感染力, 尤其係人聲既微動態, 歌者既情緒都可輕易表現出黎. 試完女聲, 當然聽埋第三首男聲, 人聲分析力依然強悍, 但男聲既喉底又好似薄左少少. 有見及此, 立即換上CARDAS CLEAR XLR, 人聲厚度立即得到明顯改善. 收晒貨.
最後, 試埋第二首既FRITZ KREISTER: LIEBESIEID小提琴, 高頻伸延都好盡下, 最正係支雞既肉地, 竟然可以喺屏風上播到. 又真係估佢唔到.
總結:
依套入門組合在我家聽了足足一個星期, 以價論聲, 收晒貨. METRONOME CD8既厚暖分析力, 加上V110既冷艷大動態. 簡真係天作之合, 如以佢地既實價黎睇, 佢地既表現比廿幾萬既CDP+前後級有過之而無不及.
數到最驚喜係部OCTAVE V110, 每邊得兩支KT120功率膽, 輸出只有110@4ohm, 其推動力與控制力之佳, 竟然可使我對大食怪屏風貼貼服服. 以我聽過既合併機黎講, v110既力水控制力應該係最好既一部!
當然, 有好多OCTAVE既用家並不同意我既COMMENT, 佢地話只需幫部V110更換前面果三支膽仔, 對於改善人聲厚度, 加強音樂味, 都有明顯分別. 各用家仲有D咩建議, 可在此多些分享. 謝謝.
