請問一下這是什麼啊？

SB4.1(你沒看錯，就是早期那張4.1的版本)和1723我都有和現在的ALC888比較過，
說實話，我實在聽不出差異，所以就使用內建的ALC888其他都賣掉了 :jolin:

HD Audio Realtek ALC880 demonstrates rather good audio quality for integrated audio. It sounds very much like Creative Audigy. If you strain your ears to hear the fragment details, you may notice the slightest difference (a bit better transparency at high frequencies for Audigy). However, if you extend the interval between HD Audio and Creative Audigy auditions to five minutes, it will be impossible to hear the difference.

Comparing the audio quality of HD Audio Realtek ALC880 with that of Live!5.1, the superiority of Realtek ALC880 is obvious: better-balanced and smoother playback without the abrupt, rough tones. Note that the difference between ALC880 and Live!5.1 is much more pronounced than with Audigy. While Audigy and Realtek ALC880 sound almost alike, the Live!5.1 playback differs even in tembre of some instruments.

AC'97-audio Realtek ALC650 playback also differs from that of HD Audio Realtek ALC880. Their divergence is of a different nature, than in two previous comparisons. HD Audio performs in a more pronounced and detailed manner in the low and medium frequencies range, but the high frequencies are subjectively better in ALC650. Nevertheless, AC'97-audio, unlike HD Audio, possesses a rather flat stereopicture with blurred details. Surely, everything is known in comparison, but a closer match to the reference playback is HD Audio Realtek ALC880.

Thus, the subjective comparative tests demonstrated that the audio quality of HD Audio Realtek ALC880 is of an evolutional rather than revolutional nature. The achieved level of audio quality is right up to such sound cards as Creative Audigy. Don't forget though, that the today's HD Audio sample was based on the top Realtek ALC880 codec.

請問上面這段英文是指單ALC880的晶片來是說ALC88x系列都有含在內??

用ALC88X系列的內建音效 foobar掛SSRC,ASIO
先把ASIO4ALL裡面所有BUFFER和SAMPLEs數都調到最大
再去foobar裡把Secret Rabbit Resmpler的output sample rate調大
我最多可以調到96000Hz (再上去會有爆音)
這樣音質好像變好 不知是不是心理作用
有興趣的試試

目前組合..ALC883驅動R1.84
foobar2000 0.9.5(final)+ASIO4ALL 2.8 beta2
單純用內定值播放不會有爆音了

聽起來跟之前感覺一樣
如果跟灌官版的OEM X-Fi Music比起來不會差太多
改灌游飄版的X-Fi Music勝出就明顯
簡單說ALC883比較毛躁、表現容易over，X-Fi沉穩平順、音場開闊

ALC883算是瑞昱最低階的HD，音質真的已經很不錯，至少聽音樂
搭上Foobar2000不輸外接音效卡了。最近也是下載新版的R1.84
for vista，控制介面真的很討喜，反觀SoundMax的AD1988b.......噁...這家公司到底在幹嘛。
真不好意思，連發兩文都是在鞭AD.

我今天再試了一下AUDIGY 2 和內建 ALC883
皆用FOOBAR 掛ASIO , SSRC播放
用SENNHEISER MX55VC耳機聽
AUDIGY2應該是完勝，低音夠沉比較不糊，音色較內建冷一點
不過ALC883也不差，至少沒聽到有底噪，音樂該有的細節是有。

用普通喇叭的話我滿質疑聽不聽的出明顯差異
至少我用BOSTON MM覺得插不插卡沒啥差

重取樣率不是設定為音效卡預設的48000Hz才會對音質有所提升嗎
設定到96000Hz會有幫助嗎?

另外，
重取樣還有PPHS用這個如何??
聽說SSRC很耗資源呢?
