新手揀機一問

For me........

CD player IIS output --> Upsampling convert to 192/24KHz IIS --> Digital amp. (300W x 2 x 2).
Stereo bi-amp class D.
KK.

Digital input class D controller  with cross over filter inside.

最近試緊有粒森美既20W class -D
體積衹有3x3mm,成塊板都係1/8 張咭片咁大
出奇好聲
塞入電腦机箱話咁易

45nM process + 0603 SMD components

對我來講是乏味,我正職是......
天天對住呢D野,价錢,貨期,樣辦,演示板
各大牌子analog input class d 20W 不超過美金1蚊
TI 綱上有价錢,你可上去睇睇

當然數量不是一粒啦
亦不是普通DIY友隨時買到

CD 5003  = CD 6003 PCB circuit but............

1. 5003 no ipod, USB interface
2. 5003 output level 2.25V, 6003 output 2.35V,  you will feel 6003 more punch and force.
3. 6003 mechanical (chassics) better than 5003.

You can buy 5003, change the following items, will 4 times better than 6003.
1. Full mod capacitor, no need blackgate. Budget dependent
2. Up-sampling converter to 24/192 then feed it back to internal DAC.
3. Dampling material.

For detail, please join KK CD modification class 2010.

摩机吾難,信我
除非你手震
你肯上堂,肯揸焊雞
吾難,二隻腳以上既零件,我幫你摩
衹益你

包然埋你都吾然會用

Modify the R-CORE to replace the default 100V Square EI transformer.

R-Core > Trodorial transformer >>>>> EI transformer.

Not suggest PM5003 or PM7003.

I cannot modify PM5003 then win PM7003.

Reason:
Output power.

It is totally difference circuit design of PM5003,7003.

For me, try to look at 2'nd hand of PM8001.

Modify the trodorial transformer or adding MODI isolated trasformer (1.5KW)

Please contact admin, we provide this service.

Good luck.

For your information only.

PM 4001 circuit................alll in one PK.

PM-7001 circuit..... (Seperate Preamp and Power Amp).

PM-7001 Signatue (Trodial transformer, good capacitors)

If you bought 100V water good of 2'nd hand from Japan, modify the transformer and capacitor, you will similar to KI signature version

PM-8001 is more than that.

PM 4001 circuit

鴨寮街永盛電子零件(西九龍方向)隔離有間二手餔近西九龍中心方向

$2680  PM7001  220V

吾係KI signature ver

傲版主算係咁嗱掛

買左,再教你摩

You can consider our DAC1955 DAC.

After that, you will think your CD5003 no use.

I can take it to your home to test.....

Admin 己準備好, 衹欠我的時間

好,我就帶以下東西來

1. DAC1955 KK ver with BG, SRC 狂改版
2. Lxxx PCM1702 x 2 膽輸出DAC
3. MUSXXLAND 192khz 24 bit DAC

你定好時間及可上來人數話我知

我試下請我師父Modi 上來

先旨聲明:21-26-June絕不在香港,又出差了
