最近在考慮Lyngdorf TDAI-1120這台擴大機,在John Darko的影片裡,和一些
音響網站都有提到,Lyngdorf的核心技術是全數位放大。
以下內容摘自u-audio:
"Lyngdorf 的擴大機從一開始就不走類比路徑,他們採用數位放大。將所有輸入
的訊號都化成 PCM(Pulse-code modulation,脈衝編碼調變)訊號,就連輸入
的類比訊號也要轉成 PCM 訊號,然後,擴大機以 PWM 的方式將 PCM 訊號直接
放大,中間經過最少的轉換,幾乎都在全數位領域裡處理。"
所以忽然有個疑問,如果在Lyngdorf前面加上DAC會有效果嗎?還是在Lyngdorf
把類比轉數位,接著數位放大,接著再轉回類比後,結果聽起來是Lyngdorf自己
的聲音?
國外論壇也有兩派說法,一派覺得上個好的DAC是有差異的,另外一派覺得不要
接最好,不知道各位大大的看法,感謝。
