7.1 ch 電腦sound card及喇叭

我買了部可駁7.1 ch 的HP電腦 ，Windows Vista，有onboard sound card: Realtec High Definition Audio (不知exactly 是那個model)。發覺sound card十分不理想。用耳筒聽有些古典音樂樂曲也有吱吱聲 (即是不因喇叭質素問題)，聽音樂時音色不夠靚，又好似有點偏向高音，低音又有點老牛聲。

我想聽音樂好聽 (主要是古典音樂) , 加甚麼sound card 適合? (註︰古典音樂經常有雜音問題)

非常期待...... 有人介紹Creative，Signal to Noise Ratio 是104db。貴一些的有109db 至120db不等。請問是否Signal to Noise Ratio 越高越能解決上述問題? 104db 是否足夠?

有些Sound card 沒有寫明是否support Windows Vista ，是否到時會有問題?

另一條問題: 想在睡房放電腦喇叭聽古典音樂(左右兩個喇叭)，怎樣的configuration 既經濟又好聽?

1. Seperate the noisy source from SMPS (power supply)

2. The S/N ratio show in the sound card may be the figure of the S/N ratio of DAC (from DAC datasheet)

3. Suggest sending out the SPDIF to decode in external source. Like DAC.
Or direct drive the Class-D using Digital input class D. (HiFifever coming soon)

Thank you, KK.

However, I'm very green regarding hifi and can't understand your termiology.  Can you advise whether 104db can solve the above problem?  Thanks.

No.

You can use simple measuring equipment to test your S/N ratio.

Asus ge Xonar DX around 700 quite well, I just buy it
