首先要知道甚麼不是數碼amp：數碼amp不是加了DAC的合拼機、數碼amp也不等於class-D amp！

A amp？CLASS A 呀！？可以好大！天價之嘛。。。。。但如果真正純 CLASS A 200W，已經係無敵，世上冇喇叭推唔到，所以你講 o既弊處係多餘 o既。

不是A amp
我想寫 D amp => Digital Amp才對, thx!

D amp could easily have 500W even 1000W, but it does not mean good. A ching found that his old 1000W D amp could not drive his Adam passive speakers well but a Class A 60W amp can achieve an amazing performance.

可能寫得唔夠好引起誤會，我這裡不想 out topic 討論有關 class D

小弟所說 "功率不大的弊處(約200W)" 是指 >>Digital Amplifier


#2 一開始亦有ching說了 >>>  第一件事，數碼amp 同 class d amp 係兩樣野，別誤會

  I understand your meaning, but how about "用威馬部DAC, 又平又抵用", can it read wav file by external USB HDD???
