你無聽過回頭燒更旺咩
我無聽過, 但我親身證明左...
我也留意到樓主話自己讀電腦所以唔會相信USB線材有甚麼影響。
我個人是文科人，對技術性的講論不熟手。不過昨天看線材Review時就找到一個附文。
PS. On computer-audio differences, resident IT experts Marja & Henk had this: "It's a fact that with network communications (computer data transmissions) there are differences in ethernet cable quality. CAT 5 was superseded by CAT 6. When a standard CAT 5 cable for audio purposes gets switched to CAT 6, there's already a substantial audible difference. But it goes well beyond cables. Think hard disks. We notice differences using various hard drive makes/types for audio playback. In our XXHighEnd dedicated Windows PC our WAV/FLAC files store on USB 3 hard drives. From there data is intermediately stored on another disk before being transferred to memory from whence actual audio ‘playing’ is performed. The kind and type of intermediate disk has an influence on the perceived playback. Western Digital sounds less good than Toshiba where SATA disks are concerned. Disks spinning at 7.200RPM sound better than 10.000RPM spinners. Using a solid-state drive is not as fine/good as a slow-spinning SATA. So far the best is a RAM disk created in physical memory. Audiophiles have trouble wrapping their heads around the fact of no real time component since all data is cached and/or buffered somewhere along the path yet everything still has an influence. The only thing we can think of is that it has something to do with transitions between protocols. For an analogy, computer hacking occurs at the most vulnerable side of software - its protocol boundaries. When HTTP (which is nothing more than a copy protocol) transfers data from server to client (a web browser receives or sends data to a server), there's a conversion of protocols. At that crossing point hackers can interfere. It goes far deeper but the general idea is that at each crossing point from HTTP to XML, SQL or whatever protocol is involved, there's a weakness and an opening. The same seems to be true with audio content at a low level. In computer audio data migrates from one protocol to another. At every protocol translation point there's an influence."

俾你地讀科技的人去理解吧。
我也是文科人, 睇唔明... {:1_332:} {:1_263:}
從小5開始耳機
係黎日本以前出哂所有玩具
黎左日本以前汁左套平野
越燒越低端{:6_203:}

你係日本？
我係東京喎。久唔久去中野新宿「參觀」名機。

我去左次ヨドバシ就執左幾件野，依家家用仲變埋成套MIJ添...

我往橫濱,依邊幾間hifi鋪d機比我玩得七七八八
講真d日本人真係好好人,差唔多日日去聽但咩都冇買過
都仲係好歡迎我,仲仲教左我唔少野
不過冇錢買就係冇錢買

我看了五六次左右。
那IT人嘗試用側面來說USB線是可能給音質帶來影響。
因為數碼數據理論上全是0和1, 當中不能夠有隨意的出錯，否則解碼會失敗。所以大多數人會有一個合理的假設，即傳送數碼數據是沒有可能會有錯誤，不同材質的線也應不可能會影響到數據的傳送，否則DAC就會遇上解碼Error，有點像你在Broswer中打一個網址，但打錯了一個字母，結果也是去不了那網站。所以數碼數據必定是全程資料沒有錯，才是合理的。
而那文是指出雖然在0和1的數據是沒有錯誤，但其實由一個檔案在硬碟中直到你的耳中，有非常多不同的地方，在每一個傳送關口的轉送中，都有可能出現加入影響因素的地方。（也就是這些位置可以進行Hacking）
所以當年大家玩ipod為何由硬碟轉CF Card，再到後期有人玩SSD入iPod一樣，在音質會有變化。（上文也有用硬碟至RAM Disk作舉例，Ram Disk即是將整個OS 及所有要的檔都完全放進Ram中，那電腦使用時是完全不用與硬碟或SSD有任何資料上的交流）
我個人上其實完全唔係線材派成員。當年也只是因好奇而買入了一條二手的Furutech 藍USB線。（當年巿面還沒有現在那麼多發燒USB線）用在我的不算高級的Sym2 已經是有明顯分別，不過我部Dac本身同軸強過USB頭太多，所以最後都沒有繼續用那USB線。
我在理論層面還未了解得到實際上為何有分別。但在聽感上卻是太明顯。就算不說是「提升」但肯定是「不同聲」

都仲係 ...
你去唔去中野耳筒會？我幾年都無去過。
我成日去Audio Union去聽Stax，試過超過不下廿次，最後決定好買Driver卻不是幫襯佢地，哈。
