B.M.C. Audio的產品一向以物超所值在市場上具有相當強的競爭力,享受High End不用天價,務實的訂價策略造福了許多發燒友,B.M.C.的成功絕非偶然,而是總裁Carlos Candeias先生所帶領的團隊在High End產業具有強大的研發與製作能力。PURE系列更是B.M.C.產品線中最熱門的,平易近人的價格享有B.M.C.的技術與聲音,獲得許多好評。
現在PureDAC已經近化到MK2版本,雖然外觀一樣,但裡面線路已經完全更新,其與一代主要的不同在於:
● 非平衡耳擴輸出大幅升級,擁有自己獨立的放大模組,聲音品質大幅提升,更接近平衡耳擴輸出的表現。
● 新的耳擴放大使用了新一代的DAPC-I/V模組 (digital/analog power conversion),採用混合式LEF (Load Effect Free)架構,雙極(Bipolar)的設計在MOSFET電晶體的電流供應同時控制著電壓輸出。
● 類比輸出部份(line output)也採用了改良後的混合式架構,聲音品質也提升。
● 新的SPDIF解碼,完全支援24bit/192kHz,並且對不同取樣頻率的訊號來源擁有更高的容納能力。
● 固定增益的DAC輸出模式,只要同時按下音量控制就可啟動,此時音量就會固定。
● USB管理改進,擁有更穩定的啟動程序及解除保護。
● 時鐘管理更為精進,聲音品質更好。
看來原廠說的”Better is the enemy of the good”,還真是一語中的,”更好”是”好”的敵人,原本PureDAC就已經很好了,但現在MK2硬是更好。PureDAC是一台帶有平衡前級及平衡耳擴的DAC,搭載了B.M.C.專利第二代的Digital Intelligent Gain Management (DIGM)增益管理技術,不需改變輸入的訊號就能進行增益控制。為了訊號的純淨,前級與耳擴的音控是獨立分開的,當然在PureDAC上還有B.M.C. link端子,用以連接B.M.C.的擴大機,以發揮B.M.C.專利的Current Injection (CI)技術。PureDAC採用全鋁金屬本體,並附有專用遙控器。
