請問CAS是什麼？麼該要點樣搞呢？
只知道是用電腦接駁DAC再駁AMP聽歌，其實同用電腦聽MP3駁AMP聽歌有什麼分別呢？是否一定要獨立DAC再駁AMP呢？CAS是否不可以用MP3檔？如果是？麼該是什麼檔？什樣可以下載到呢？
我用緊ONKYO 808，前置 QUAD 12L，如果想玩CAS，應該要加什麼呢？
請指教。 CAS=computer as source, 你用電腦做訊源已經叫係CAS Ching 咁插隻手指落blu-ray聽咪即係一樣？ 本帖最後由 TommyLCW 於 2011-4-30 11:54 編輯
CAS ( Computer As Source) normally means using some computer softwares to play music files into analog signals. e.gmedia player, real player , but especially, iTunes, FOOBAR2000, APE player , FLAC player.
The latter group, mainly free at present, makes uses of the LOSSLESS formats and equalizers for decoding and processing. Then feeds the analog signals to a2.0 or multi-channels pure analog amplifier.
As the software upgrades, esp. in preset equalizers effects, you get upgraded SQ (sound quality).
Simply speaking - Software converters free of hardware DAC's.
Music are downloaded and lossless , processors are free ( in updates, at least and ...)in contrast with different DACswhich are needed to buy for newer versions/ parts periodically. Finally, you also enjoy the convenience of huge storage of continuous musicsinside a single low cost Hard disk ( say 1 TB) .
