My understanding/rationale is that optical transfer digital signal while soundcard provide analog output.  So.  Did I mix up optical fiber and optical cable?  

Well, what a good question! I am not sure if I understand correctly. Anyone please correct me if I am wrong ...

The soundcard CAN do digital-to-analogue conversion. If you plug any thing (active speakers for example) into your traditional green jacket, you're USING this function.

But the soundcard can also just send the digital signal out without doing the conversion. In doing so, it just 'collect' the audio data from xp system, applications and so on and process it and may even do some 'tweaks' and output to the optical link directly.

Take this as an example: (1)you're playing music through Media player classic AND playing MSN, and (2) you then work on the system, which from time to time have system sounds (like beeps). If you do not disable the system sound or other channels, all the sounds will be processed by the soundcard 'in one go' and send it to the optical link. So when you connect your MD walkman to the optical link of your soundcard, you get pure digital signals, which are in turn composed of all the digitals siganls being processed by all your applications and even xp system.

DUnno what I am saying Do you know???

It's HIFIDIY's USB DAC !!
You know how to MOD gears ma??? I envy u so much!
This one should be good. I think you can buy it from Taobao rather safely. I should have bought it when RMB was not  ...

圖中那台機就是我的，我個blog(查看我的資料就有)的DAC版有寫如何mod，我也在亦軒那邊出過post
我覺得它好值得玩，可玩性甚高(因為機箱空間相對其它機大，但也可說是缺點)
買了的用家千萬別離棄它！當然它是走HIFI路向，所以5.1,DTS無它份

無開關....的確是最大敗筆！不過他們說旦因為會出外接升級電源才不加上.....

Dijeridu & Chacha7,

I google the DAC name and found a Club in MK selling it.  Seems the price is going up.    Do you have any store(s) in mind that you think worth trying.  Please PM me if it i ...

WHO hing, are you talking about 亦軒耳機音樂世界  ??? I dunno if other shops sell it.
But you have a MD, try try your MD first. Your desktop may be too noisy to play good sound (even though there are great improvements after connecting the MD or USB DAC). This is my case. My 805D+ MSI motherboard + PSU combo was too noisy to give hifi quality sound, especially desktop system tend to be loaded with a lot of programmes which will interfere music performance. I suggested using MD for the desktop since you have it already, and there will still be some improvement (but there is limit to this improvement!).

But it's worth trying the soundrigor thing for your eeepc and headphone. You will definitely see SUBSTANTIAL difference between using the jacket provided by eeepc and using USB DAC. If not, I'll buy your USB DAC

我無幫人裝機或mod機，一來自己完全無時間...
就算有時間，我都會不段測試、較聲，然後寫出來分享
測試較聲所需時間是非常非常漫長的....
雖然知道香港人 最緊要快和方便
但教會大家去做去mod比起幫人直接改會更，更多人受惠
如果你有朋友會焊接、解拆技巧，建議找他們幫忙，一起玩玩

小弟只算是一個裝配工，不大會電路方面知識，也是small potato呢！

我自己本來係打算901加usb dac加個amp仔在睡房用
但而家打算等到9月30，看看有無新機出，無都要買，因為要準備一台機出國用
見你用eeepc駁hifi忍不住要回應一下

雖然知道香港人 最緊要快和方便 ... dun say this way la We all have limitations ma. It took me years to learn how to manipulate pc (5 years ago, I got fed up by getting viruses and the blue screens of xp so I started to learn pc myself now I know how to assemble desktop myself la) ... I just haven't the time (now) to learn MODDING though I know Hifi fever have courses .. maybe later. But life is too short to learn so many things at the same time

As you said "我無幫人裝機或mod機，一來自己完全無時間..." I perfectly understand ga. I asked since I respect the design and SPIRIT of hifi diy very very much. I want to play their products but really dunno how to make them myself, which is a pity. Yet, your efforts and theirs are SUPERB!
