THE REAL phono MK2 旗艦唱放
經過2年半的究發,THE REAL phono MK2終於完成.
聲音和功能都超越前作(無論是4件式THE REAL phono 或 2件式的THE REAL-TU phono).
全新設計的放大線, 大幅減小使用交連電容, 改用直接交連, 失真率和對輸入容許度亦改進了, 聲音得到實質的大進步.
MK2電源供應部份比前作4件式THE REAL phono再加強一倍, 前作1個電源供應只有1組高壓穩壓供電, MK2的電源供應部份內有4組高壓穩壓供電分別獨立供應左右input和output級.
內置2組MC step-up 牛, 各有獨立阻抗選擇制.
主Gain制配合雙再加low/high gain 有6×5= 30個變化.
