基本同意老马褂个"10倍价格"的理论, 但是我问这个问题不是没有原因的: 我台式机在Foobar的output里面选ASIO驱动时候 (好像ASIO和DS(DirectSound)确实能听出区别, 可能我Asus Xonar D1声卡驱动问题) 一遍听音乐一边 浏览网页 会有drop-out/pop/"噗噗"声音 (什么都不动就没有这种声音) 在head-fi上有些人有一样问题 不过没有完美solution,有人提到可能是电源的问题 (想到我装了一个GTX460显卡,但是电源是OCZ 450W的) *link: http://www.head-fi.org/forum/thread/526734/emu-0404-usb-pops-while- scrolling#post_7118607 *参考: What is DPC latency? “If any kernel-mode device driver in your Windows system is implemented improperly and causes excessive latencies of Deferred Procedure Calls (DPCs) then probably drop-outs will occur when you use real-time audio or video streaming applications” – http://www.thesycon.de/eng/latency_check.shtml
