不是小改款的進階線路改版

假如我們從ARC的前級演進來看，Reference 6應該與之前的Reference 5與Reference 5 SE，Reference 5面板還是方形黑色按鍵，到了Reference 5 SE已經比照40週年紀念版本，換成小圓型按鍵，而現在的Reference 6則與G系列相同，換成大圓形按鍵，至於線路的變化，從5到5 SE，主要是換上與40週年紀念相同等級的鐵氟龍交連電容，外加ARC新開發的變壓器，但是到了Reference 6，5 SE的特別零件都在，但是放大線路又有改進，原本5與5 SE只有4只6H30訊號管，到了Reference 6變成6只，看來放大線路改了不少。電源供應部份依然維持6550配6H30，不過ARC說這部分也有細部的改良，譬如變壓器尺吋增大了些，只不過沒有擺在一起比較，外觀上看不太出來差異。
