I use simple thinking.
In step 1, music on CD is converted into 0101, you copy the 0101 file among harddisks won't change the sound quality.  In the last step, this 0101 is somehow sent thru  ...

相對來說是正確的，因為問題還有每次播拾取CD訊號都會不同
其實不只是0101的，還有Jitter及外來扞擾影響著
是否準確保持原有數碼訊號也是問題
但我都朝這個方向去玩，繼SB2後，遲d再玩獨立APE player

Whoa ... I think we're getting too deep here. Yes, Jitter is the 'timing' data of the audio signals, as I first mentioned in the post. If timing is incorrect, music sound bad.

But there're a lot of factors affecting performance, perhaps too many (the discussion can go on forever). Having right jitter is one key step, but there're many 'steps' awaiting you.

So WHO hing, my experience is up to a point, let all those technical jargons go! Just try the simple setup first, if it's good, then forget about learning more for a while and enjoy your music! Cos I realise I can spend a lifetime learning the technical side of music and end up having no time to enjoy music

SO now what are you planning to experiment? I think it's ...

(1) eeepc + EAC + Foobar2000 --> $330 USB dac (USB cables) --> headphone (or speakers)??

(2) Desktop + EAC + Foobar2000 --> FREE MD ($50 optical cables) --> speakers

It's less than $400!!!
From a cheap cheap point of view, try MD first

"Dare not say any report la, just some subjective feeling when comparing the output quality of
1/  UA processing digital audio data (I start to wonder how "true" it is ); and
2/  Philips chips set processing mp3 format data
Right now I have absolutely no idea"

Sorry, what do u mean here ... What is UA??

I think I will go for option 1.
I anticipate that it will give me more fun.  I can actually use it and share the experience with friends.  But for the cable, I don't think I will play with it for more ...

Really wanna know how your experiment will lead you to ... will you use headphone? There are issues about matching the "impedance" of headphones and the output of the USB DAC ... I have been thinking about whether mentioning this issue or not since I think more info will destroy the impluse and fun .... but I think you're those who prefer to learn and know more and i dun want to be beat by you after you have bought the dac ..

So one final question, will you be using headphone or speakers???

What is it? Seems very convenient? Model no??? I'm interested in gadgets ...

NX-U10. Of course it is convenient, you can find it at tom-lee music.

You say YAMAHA cheap ?!?  no way la

The NX-U10 may not be the ultimate in high fidelity... When I first spied the NX-U10 USB powered speaker system at CES, I was pretty impressed.

Simple is the BEST
越簡單越直接越好
還是那句，不要麻目追求器材

耳機的而且確要注意與耳擴之阻擴匹配
但我覺得可以簡單點分 低阻抗 細過120ohm 和 高阻抗 120-600 就OK

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 ...
