小弟我之前在DIY Coral時.........
也是被單端接地該接那邊弄的頭暈暈........ =.=
所以直街寫信去問了AQ........
以下是回信......
===============================================
Dear XXX,

The drain wire (the silver wire) should be attached at the #2 (or receiving
end) of the cable only. Do not attach it at the sending end.

I hope this helps.

===================================================
所以說AQ是將單端接地的那一端接在後級/耳擴端.......
訊源端則是不接........
也就是CD-Player (X) -> AMP (O)
===================================================
Dear XXX,

Do you already own the Coral? Or do you intend to order raw Coral? You
should know that factory terminated Coral uses a proprietary Resistance
Welding technique which is vastly superior to soldering. Either way, I
would recommend letting us take care of it for you.

If necessary, you can call us at 949 585 0111 to request a Return
Authorization Number.

Regards,

Alasdair Patrick

這一封是我第一封寫去問時.....
AQ的服務人員建議我購買廠製線....說AQ的廠製線用的是特殊焊法............
會讓聲音更好.........不過這點我就不清楚了................
