　　B.M.C. Audio的产品一向以物超所值在市场上具有相当强的竞争力,享受High End不用天价,务实的订价策略造福了许多发烧友,B.M.C.的成功绝非偶然,而是总裁Carlos Candeias先生所带领的团队在High End产业具有强大的研发与制作能力.PURE系列更是B.M.C.产品线中最热门的,平易近人的价格享有B.M.C.的技术与声音,获得许多好评.
　　现在PureDAC已经近化到MK2版本,虽然外观一样,但里面线路已经完全更新,其与一代主要的不同在於:
　　● 非平衡耳扩输出大幅升级,拥有自己独立的放大模组,声音品质大幅提升,更接近平衡耳扩输出的表现.
　　● 新的耳扩放大使用了新一代的DAPC-I/V模组 (digital/analog power conversion),采用混合式LEF (Load Effect Free)架构,双极(Bipolar)的设计在MOSFET电晶体的电流供应同时控制着电压输出.
　　● 类比输出部份(line output)也采用了改良後的混合式架构,声音品质也提升.
　　● 新的SPDIF解码,完全支援24bit/192kHz,并且对不同取样频率的讯号来源拥有更高的容纳能力.
　　● 固定增益的DAC输出模式,只要同时按下音量控制就可启动,此时音量就会固定.
　　● USB管理改进,拥有更稳定的启动程序及解除保护.
　　● 时钟管理更为精进,声音品质更好.
　　看来原厂说的"Better is the enemy of the good",还真是一语中的,"更好"是"好"的敌人,原本PureDAC就已经很好了,但现在MK2硬是更好.PureDAC是一台带有平衡前级及平衡耳扩的DAC,搭载了B.M.C.专利第二代的Digital Intelligent Gain Management (DIGM)增益管理技术,不需改变输入的讯号就能进行增益控制.为了讯号的纯净,前级与耳扩的音控是独立分开的,当然在PureDAC上还有B.M.C. link端子,用以连接B.M.C.的扩大机,以发挥B.M.C.专利的Current Injection (CI)技术.PureDAC采用全铝金属本体,并附有专用遥控器.
