都睇下咩牌字 o既，我自己野唔講啦，Asus 咪真 balanced o羅，有埋異步 USB 同 preamp，加對 pro grand o既 active 喇叭，配埋線都可能幾皮搞掂。

好多人話用DAC做埋pre啲聲會乾啲，係咪真?
同埋佢嘅pre係真正放大定係衰減?{:1_342:}

咁係 Fully Balanced 定 Differential Balanced ?

排除pre做得差，用DAC做埋pre啲聲會乾多數係因為個pre係無源，冇真正放大，只係衰減，output/input impedance唔match引至signal lost。
其實真正有源pre有放大會overall system gain 夠高保証到動態同擺幅之外，就係個gain補償返output/input impedance唔match引至signal lost。
Asus佢嘅pre係真正放大，如果無源衰減式，最少可以行少兩粒opamp。

想上堂！？未交學費喎！{:1_253:}
我當你講緊 o既係正確理解 o既 Fully Balanced 同 Differential Balanced，理論上，一定係 Fully Balanced 好，Differential Balanced 只係借差動電路個負端接 balance，變相行少一級，同正端會有輕微 cross talk disustortion 同相位差失真，但實際上，fully balanced 如果正、負 amp 唔 match，負面影響大過 Differential Balanced o既 cross talk disustortion 同相位差失真，所以 fully balanced amp 會貴，好似我都 int.amp，如果唔係 fully balanced，最少平 2K。

呢部好似$4XXX，如果係咁都算幾抵玩喎。
