Sound Card!!---------一陣再講!

作者: dynamicdog 時間: 2006-6-7 00:19
問你死未! 有得玩OPAMP
一個聲道一粒雙運放! 我用2粒AD797AH聽歌
7.1 ch
光纖out
遲下得打算改同軸
原先打算買Creative Audigy4 或者俾多d錢買onkyo , 一睇呢張野D用料...真係不得了. 平靚正! hkd$300!!! 有找! 國產好野!

作者: dynamicdog 時間: 2006-6-7 00:24
功能齊全!
我就用foobar聽歌.
聽戲用Media Player Classic
DTS-ES , DOLBY DIGITAL EX 玩齊, 入onkyo 702睇戲

聲方面唔係話天下無敵,不是什麼必買之作,唔算絕對係同級中之最
但是筆者真係放左入自己部PC度玩緊

作者: deepsea 時間: 2006-6-8 00:06
利害！利害！
最重要自己玩得開心

作者: dynamicdog 時間: 2006-6-10 15:25
Deep Sea 師兄:
你部電腦Audio個part點玩? 交流下啦

作者: dickson 時間: 2006-6-15 09:58
dynamicdog, deepsea 兄:

見你地玩得咁開心, 真係十分想一齊玩, 但是要等搬屋後(很快!!!).

dynamicdog 兄的sound card 是否在"新高登" 二樓買?

啊! 重有想請教你Capture有Freq Response Curve是用甚麼設備?

請多多指教!!

Dickson

作者: dynamicdog 時間: 2006-6-15 19:51
Dickson 兄
sound card "新高登" 二樓買, 個間野最正係好多風扇賣, 有埋幾多dB,幾多轉, 清清楚楚. 幾好
走去其他地方問sale,十問九唔識
設備我唔清楚, 我網上搵圖

作者: dickson 時間: 2006-6-16 15:51
Dynamicdog兄:

請教有否用Onkyo的Shielding Card, 在這間Shop有得賣!!! 你的DAC AD797換了有多大及那方面的進步? 見你出Signal是用DVI轉色差, 還是S-Video出電視? 我現在是用ATI9550, 有DVI及VGA output, 是否有DVI to 色差 Adaptor? 問題多多..... 還請多多指教!!!!!

Dickson

作者: deepsea 時間: 2006-6-17 23:26
Dynamicdog,

小弟是用小弟用傳說中的 RME HDSP9632 :-({|=

作者: happy4 時間: 2006-6-30 13:15
Hi Dynamicdog,

Is that sound card have digital out ? Thanks.

I like the OPA socket.

Happy4

作者: dynamicdog 時間: 2006-6-30 15:22
Happy4 兄 ^_^
張sound card有digital out, 有光纖! 欠同軸!!
但係.....我見張card有同軸既位...遲下試下加上去用唔用得

作者: happy4 時間: 2006-6-30 22:58
Hi Dynamicdog 兄,

I see, if the coaxial digital out work, it should be great.

Waiting for your good news.

Happy4

作者: deepsea 時間: 2006-7-5 23:36
Sound Card 中的 AES 會比 coaxial 好聲，但只能運行單聲道或雙聲道。

作者: happy4 時間: 2006-7-6 23:53
Hi Deep Sea,

Do you mean, analog output can use AES ?

作者: deepsea 時間: 2006-7-7 16:51
[quote:9aa4eae2b4="happy4"]Hi Deep Sea,

[/quote]
AES only for Sound Card digital output.

作者: happy4 時間: 2006-7-8 14:37
Hi,

I buy the sound card, however the OPAMP is surface mount no socket.
After modification, using 2111 for 2 channel.

Happy4

作者: dynamicdog 時間: 2006-7-9 01:33
Happy4 兄,
手工幾好! 2111聲我都幾鍾意, 聲底清, 分析力又高, 音樂感又好.
你可以試下搵2粒111,加個單轉雙座,加2粒0.1uf - 1uf電容,有驚喜
我就試過用2粒627, 幾明顯

張soundcard除左OPAMP, 仲有無其他地方可以升級呢? 比D意見Ar

作者: happy4 時間: 2006-7-9 15:10
Hi dynamicdog 兄,

手工just ok, 2111 performance good by listening, however the test result not so good compare to the orignal one.

2111 result
Frequency response (from 40 Hz to 15 kHz), dB: +0.41, -4.36
Noise level, dB (A): -83.2
Dynamic range, dB (A): 80.8
THD, %: 0.021
IMD + Noise, %: 0.036
Stereo crosstalk, dB: -81.6
IMD at 10 kHz, %: 1.026

Your suggestion is good but much expenisve. 2粒111 加個單轉雙座,加2粒0.1uf - 1uf電容 should expensive than the sound card
I will try 2粒627 first, since I have 2粒 on hand.

Further improvement plan, may change the cap to OS-CON & add copper shielding on the chip.

Any different for 2粒627 & 2粒AD797 ?
And have you try the 637?

Have Fun on this sound card.

Happy4

happy4,

最重要玩得開心，玩死了又不會肉赤！

作者: dynamicdog 時間: 2006-7-11 23:44
玩死左都無所謂啦. 三百蚊學費都要啦
其實我都想換Caps..但我見有D難度

作者: happy4 時間: 2006-7-12 01:31
Hi,

Learning from expert, use 2 soldering guns together is much easy to remove the surface mount Cap.

Happy4

作者: dynamicdog 時間: 2006-7-12 02:33
Happy4兄,
講個秘密你知, 唔好同人地講
.....
我未試過換surface mount Caps, 你唔講我都唔知可以咁樣拆出黎
之前見到呢d野都怕怕

作者: happy4 時間: 2006-7-26 01:06
Hi dynamicdog 兄,

Just buy the Cap, & quick do the modification.

Hope sound had improvement.

作者: dynamicdog 時間: 2006-8-1 00:33
Happy4兄,
改左OS-CON有咩感受?
清左, 實淨左?

作者: happy4 時間: 2006-8-1 01:01
Hi,

改左OS-CON後,
真有喜出望外的感覺,
家中像多了一台迷你 Hi Fi.
背景清左, 低音實淨左, 樂器感覺真實了很多,整體分析力增强.
非常值得改. 成本少, 效果大.
如換上更高級的OPAMP, 應有更佳的表現.

以上only for 2 channel 的表現

Very happy

作者: happy4 時間: 2006-8-5 16:11
Hi,

Beside sound card, I find my 2.1 speaker also have space to modify.

I change the opamp, cap, connecter, diode.

The performance improve a lot, very funny.

作者: deepsea 時間: 2006-8-6 23:51
會否保品貴過主人 :roll:

作者: happy4 時間: 2006-8-7 01:52
Hi,

You might be right, let be count on the cost.

Sound card around $300
mod part
Cap around $60
Opamp 2111KP + IC socket $75
total $135
Upgrade cost 50%

PC speaker (around $250)
mod part
RCA socket around $10
inter connect cable $27
Cap around $50
IC socket $10
Diode $12
OPAMP 627APx2 + adaper $80
Upgrade cost around 75%

I think 75% for upgrade seem too expensive.

Just for Fun.

作者: dynamicdog 時間: 2006-8-24 20:13
我個張換左幾隻ELNA
試下同張Audigy2ZS比較下...

作者: dynamicdog 時間: 2006-8-24 20:14
OP用 BB OPA2111KM 平靚正, 分析力高, 又夠清!

作者: dynamicdog 時間: 2006-8-24 21:39
加入同軸輸出! WORK!

作者: dynamicdog 時間: 2006-8-24 21:44
剛才上左去觀塘音響借左部DAC-AM試下張sound card
一試之下, 可以提升到24bit 44.1KHz, 48KHz, 96KHz!!! 再入部DAC解碼!
分析力緊係堅啦!
乜話? 你部CD機仲行緊44.1KHz? 咁OUT呀! 我部電腦都96KHz啦 ...ha ha ^^
最衰人家要收工, 遲下再上去比較Great March!

作者: happy4 時間: 2006-8-27 16:44
Hi,

Good New for me!
I will try 加入同軸輸出!
However Bad new on my card, after I change all the Cap to OS-CON, the sound become worst, may be OS-CON doesn't suitable work in all position on the sound card , I need change back some of Cap to orignate.

I also visit the Kwun Tong Shop on last week.
I like the sound for great march(modify version) more than the DAC-AM. (just my opinion)

Waiting for your result

作者: dynamicdog 時間: 2006-10-3 21:44
OS-CON應該只合Digital用

作者: dynamicdog 時間: 2006-10-3 21:50
great march個jitter做得好. 打開見有3隻clock

作者: dynamicdog 時間: 2006-10-11 11:31

呢件野好似０岩我地玩

作者: dynamicdog 時間: 2006-11-29 21:30
整左部新玩具!

又可以USB直入
