1. 不要指望能夠處理電腦裡面那一堆雜訊
什麼無風扇、關掉HT都嘛杯水車薪
光是頻率產生器的PLL模組就夠受的了
要解決也很簡單,光隔離就好
便宜的方法就是用S/PDIF
主流廠商Realtek的內建音效卡都支援到 24bit 192kHz 足堪使用
但S/PDIF只支援到兩聲道,所以超過兩聲道就要靠別的方法
(請參閱: 音響光耦合)
基本原則就是把電腦與音響系統的直流地完全隔離
2.數位音效不會因為傳輸線材品質而丟失任何解析度,只會因為數位處理而丟失
那種貴上天的光纖線、USB線還是各種數位線材不會有幫助
(那種爛到會鬆脫或是掉封包的線材當然還是不行,基本品質還是要)
請把費用花在類比線材
3.直流地以及直流電壓是務必要隔離的,至於交流地隔離是比較昂貴的目標
這已經有很多資料了,從最困難的自建水力發電
到相對便宜的從總電箱拉獨立電源給音響系統都有
你也可以選擇用鋰電池跟充電隔離的方式(人工換電池)
