S21 MI Laboratory Series Integrated Amplifier

  S21機內使用的元件都是高級製品,包括1%誤差的金屬皮膜電阻,WIMA電容以及小數值的鉭質電容,以及ALPS的音量VR。

 



前級部份使用了Burr Brown的OPA 2604.
  後級部份每聲道共計用了兩對50MHz功率頻寬的SANKEN 25A / 295 / 2SC3264對裝晶體做為放大,加上四顆10,000uF/100v 的濾波電容器以及大型電源環型變壓器.

  頻率運作規格廣達1.5Hz~250KHz(-3dB)這個規格不但遠超過CD的頻寬範圍, 就算對應SACD,DVD-Audio等新世代數位訊源.
