所有貴既電容己買(Full Blackgate capacitor, Black WIMA capacitor)
NS Op-amp LPF 己有
面板PCB (單面板layout 中)
MP3, AAC, WAV to IIS module layout 中
機箱八月中
最快九月中閞班, 不過..........
可以先砌 PCB先, 砌完個 25磅鋁箱就番
乜孔都吾駛鑕, 只用上screw
Plan A, B : Difference on the components
Plan C, D : Difference on the base unit
Plan E,F : Balance config VS Un-balance config.
If you don't have balance in preamp, suggest you make the un-balance one to save money and have better performance.
Common section:
SRC + USB module
New design front panel (can upgrade to AAC to IIS)
2 R-CORE (Analog and Digital)
6 button on front panel
Play, FB, FF, Source, SRC On/Off . Display On/Off
