玩CAS前前後後大半年了，可以將小小心得與大家分享。
個人認為CD係最主要音樂訊源，所以系統一定要將16bit/44.1khz處理好，更高解像的音樂檔案相對比例較少，質素也不一定高，在高質素音樂檔案未成為主流以前，還是攪好基本的red book format來得化算，說實在的，red book format實在不比CD player 差，超出的也有很多。
很多人都用電腦做訊源，pc 兩大系統windows 及Mac，兩者均有眾多軟件。
在windows，我選用的是musichi 及StealthAudioPlayer, 兩者特點均在於用wasapi，同時又不用太依賴windows o/s，出來的聲音非常乾淨，前者要幾十歐元，但其music library 非常好用，開發者下了一番心思在古典音樂的資料整理，能按作曲家，指揮，曲目類型等多達數十種類別來整理，喜愛古典音樂的人一定覺得非常有用。
Mac 聽音樂的效果相對較差，好的軟件又很貴，還原基本步用itune,vox其實勉強可以接受，花一點錢用decibel或audirvana就已經更上一層樓。
無論用windows或Mac其實最大問題在於其內置音效卡太差了，很多人都用外置音卡以改善音質，但又面對電源、硬盤或這或那的問題，最後要添置種種防噪去噪的補品，有違CAS簡單易用的原則。其實最有效最簡單是用usb to spdif將音訊導出，既方便又有效，市面產品多的是。
當然如果懂linux的話，audacious是不二之選，音質絕對比Mac或windows勝一籌。
如果不想佔用電腦，那麼voyage mpd 或SBT 都是價廉而效果上佳的選擇。
至於近來湧現於市場的music server，大都是運行linux的電腦而已，聲音大都不俗，只是性價比不高，特別是那些有ripping功能的，總會對音質產生影響吧！這些廠商總是在抄襲，毫無創意可言。要是選擇，還是最早放棄CD盤的Linn值得捧場。
要說是最好的CAS播放器，現時是剛剛到手的SD transport 384, 呢部日本仔嘅作品的確好聲，一下子將我所有電腦及CDP打低，成為現時最主要播放器。
玩CAS另一重要部份是DAC，過去幾個月用過的不下十部，體會甚深。
第一點是不要過份迷信於晶片，須知晶片只是處理器，是DAC的其中一個組成部份而已，其他如電路，時鐘等都影響著整體效果。很多國產DAC用與Linn同樣的晶片，但有多少能有同級的聲音呢?又好像近來熱爆的ESS9018，這晶片最主要功能一個是播放DSD檔，另一個是八聲道播放，最先採用的其實是oppo，好定不好就自己判斷啦！而家可以同時有八聲道同DSD嘅產品印象中只有exasound，呢班加拿大人開發咗usb to i2s driver，因此可以將八聲道或DSD送到9018晶片作解碼。其他流行嘅9018DAC，有幾多有八聲道呢?如果得兩聲道，點解唔用好的嘅9012 chips??

CAS目的不一定為方便易用，玩得精set得好係好過轉動的盤子。
Linux environment 何不試mocp :) ...
TMSulcata hing is right.
In Linux environment, Audicity and MOCP (with or without serial console mode) are sonically much better than Audacious.
However, Audacious can play CDs & output the digital signal directly whereas Audicity & MOCP can only play files.
Chow hing,
it's already a player, just plug in sd card, then you can play the songs. It only can play wav files and if you have appropriate connector and 9018 chips, you can play DSD files as well.

CKKeung hing,
mocp is good but MPD has same kind of architecture, ie command line operation, so i don't think any big sonic difference.
audacity is for studio use and a bit too complicated as far as configuration is concerned. people are easily to get stuck on Jack server and to be frank, i don't find it sounds far better than audacious.
The advantages from linux o/s is real time kernel which make it superior than other o/s.
foobar 2k is good, but the configuration too complicated for newbies.
actually, many good tweaks around on the web but i find most of them a bit artificial.

hkborn hing,
This time I have to disagree with you on the sonic qualities of Linux music player softwares. In my & my friends' systems, the difference is very significant : MOCP > Audicity > Audacious.
However, I do agree with you that Audicity is not user-friendly and real time kernel is the reason why Linux is much better than Win & Mac OS.

CKKeung hing,
no worry, it's extremely normal that people have different views on listening experience, otherwise there will be only one same system we all use . You may have a go on voyage mpd, or try mocp on voyage linux, at least u can use putty to control the terminal

TM hing,
how if you build mocp on voyage linux, you can then control the terminal by remote interface like putty, then no need to use serial port, worth trying wor

I haven't tried, but expect it to be good sounding
Anyway, the minimal Linux that I used is a super tweaked one that I expected it would sound a margin better.
The tweak incl hardware(seperate linear psu to CPU,mobo,SSD,soundcard,isolation of the soundcard from mobo by optical mean), software (bios, Linux OS)

no wonder you can get good sound then, it's the job of a perfectionist. It's extremely difficult for everyday user. people don't want to touch settings at bios level, theoretically it should help but today's chip is so fast that the sequence of processing should not be that significant gwa??On the hardware side, i think fanless embedded system may save a bit on your tweaking work.
Anyway, congratulate on your successful work.
