就算我起房用 EMU-0404 USB + headphone 聽歌，唔用 ASIO or WASAPI， 不如唔聽。{:6_142: ...

一樣0404usb, 夾a3x~~
用asio / wasapi 遠比direct sound 好~~
只係一張千幾蚊既usb sound card, 仲要錄音部份都佔左唔少成本, 都聽得出明顯分別~
之前用onboard 光纖出md deck 當dac, 都明顯聽得出wasapi / ks 同 direct sound 有分別~~
所以唔太同意樓上話普通野用direct sound 就夠~
有沒有試過jplay?

應該USB input 就唔係俾你插電腦用....就算得，都只有48/16，問題係USB Input 果度可能做得未夠好。
一係買個好既純DAC
一係用番CD Player
Thank c hing,
Let me clarify. There are 2 sets of USB inputs - one at the back (Type B) and one at the front (Type A). For Type B, this is used solely for connecting PC.
I am still a newbie to CAS, but from my understanding good sounds does not just reflect in the figures. The Marantz is just 48/16 from PC, but sound much much better than DacMagic Plus with a 98 something.

Yes....Figure is just not all things....
That's why we have to pay much in Hi FI =i{:6_209:}
But from studying the technology, we can know more truth on the sound.

For Optical I/O, it is not better than coaxial since the Light/Electronic Converter is not good enough in Normal Hi Fi....(The Clocking Issue)
Especially for the onboard sound card.
So you cannot use this as a reference...
You can try to connect normal PC Speaker to Analog out of onboard sound card directly or connect to a DAC (with USB / coaxial input)
and output to speaker/headphone...
If your PC environment is ok, you will find that there is no obvious difference.
But of course, if you can use KS/ASIO, just use them.

For normal Hi-Fi use, I would say basically all on-board sound cards are crap, and should not be considered at all.
From Wikipedia:
有部分使用者，套用 ASIO 設定之後，得到音質提升的結論。這是因為，ASIO 避開 Kmixer 的音量、音頻控制，所以不會受到原先音量設定的影響，而得到音量 0dB 的音頻輸出。許多使用者不會特意去調整音效主控台的音量設定，所以當音量 0dB 化之後，聲音變得更大聲（音量的差異），便往往產生「音質獲得提升」的主觀聽感。事實上在其它的 API（DirectSound、waveOut），只要將主音量、Wave（或設備相關設定）拉桿拉至最高（或音效驅動程式定義的 0dB 位置），音質與 ASIO 是完全沒有差別的。TonyTDK 發表於 2012-2-5 13:48 http://www.post76.com/discuss/images/common/back.gif
事實上係音量相同之下 就算ASIO4ALL都比DS有非常明顯既分別 主要原因唔係延遲 而係你都講左 迴避左windows remix
而低延遲同提高buffer固然對音色有影響 詳細可以自己試下

Thanks all C hings,
Actually, there are a lot of things to learn in CAS.
I will keep experimenting. But my PC knowledge is just so-so {:1_260:}
Hope I can learn more here!!{:1_338:}

所以我係話用普通器材，差別很少。

所以要知道多d呢方面既知識，除左多d上網扒文，仲有認識一位資深既音響工程師都好緊要~
