師兄。。可以講解多些嗎？小弟想玩CAS.乜嘢係MPD?線性電源又係乜？I2S又係乜？ ...

有空睇下呢幾條 link。

我懶得攪

早玩早享受，遲玩平幾舊。

latency 係咩意思?

Latency is the time it takes for an event to process.

This is just a rough figure, because you not just want to know the average latency of the system but the figure for a specific task (e.g. read data and play music)

How to achieve low latency? For example:
-Faster CPU
-Less Jobs running (also means less multi-tasking)

More technical, setting of job scheduler in the operating system is critical to the latency. Two scenario for you to more understand what this means:
1. Imagine like 紅隧口, if there is a lane (from Causeway Bay to Hung Hum) always reserved to your car, you can go from Causeway Bay to Hung Hum in 5 minutes. (an example is to reserve a single core of a multicore CPU for a specific (group of) job(s)
2. Imagine in local bank, instead of just one queue, we categorize the accounts into two "classes", those with 1M in account belongs to "privilege account" and there is a separate queue for them. (an example of job prioritization)

我本來是第一種方法:win7 +fidelizer+iusbpower+gemini+ddc+dac，
宜家剛轉了第三種方法: soundaware d100  ...

睇嚟 Soundaware 啲產品都唔錯喎！不過我好高興見到有人用這種方法，因為用最直接的方法可減少問題出現，而且可以多番啲時間來聽歌，對於不想煩惱電腦問題的師兄來講，這是個不錯的方案。

技安呢兩年反反覆覆想玩CAS/FAS ；連NAS都買左set埋 ！
不過一開聲發覺同CDP差好遠（只是用Baby級 : NAS > CA 751BD > Naim DAC > Naim 202/200） ；
考慮好耐決定如果投資落CAS/FAS…倒不如將果筆錢投放落現有CDP更實際  ！

謝 obee兄解釋，簡單地說，你可以當 latency 為產生 jitter 的其中一種途徑，雖然原理不同，但結果一樣，它會導致聲音變差。理論上電腦所產生傳輸上的 latency 會通過非同步方式消除，但聲音傳輸利用實時方式進行，所以並不適合用於多工的電腦上，結果會令音樂出現停頓、沙聲或者變差等情況。

技安兄，你用乜嘢做 Player 呀？如果用普通電腦或手提電腦想好聲都難喎！
