There are 2 pairs of 12 V output. I only used the red + black pair.

灌沙線

To eliminate harmonic vibrations, I have experimented with many different materials for 灌沙線. I tested, (深)海底幼沙, 碳粉, 鋼沙, 石英沙 & 澳門黑幼沙 (contains 海綠石). Each of these materials have different properties. Hence, they will have different audio characteristics. After much research, numerous tests & experiments, I conclude that high density, non intrusive materials with small grain size are the key factors for the best outcome. A portion of 碳粉  is added to eliminate EMF. The best results for music (分析力, 細緻度, 高中低, 密度等) are:

1. (深)海底幼沙 + 碳粉
2. 澳門黑幼沙

Note: 鋼沙會上磁
Electric current induces magnetic fields. 鋼沙 is not a natural but an intrusive material that will intrude the flow of electric currents. So it's not a good shielding material. Overtime, 鋼沙 will cut some frequencies.

I have made:
沙沙1號 (古河314Ag灌沙線)
沙沙2號 (Belden 83803 灌沙線)
沙沙3號 之 派拉利 1.5mm 灌沙線

沙沙一號 (古河314Ag灌沙線)
From the original 314ag &  沙沙一號, the improvements are not very significant. Hence, I gather the original shielding of 314ag was already very good.

大開眼界!

沙沙2號 (Belden 83803 灌沙線)

83803 has very poor shielding. It is ideal for 灌沙線. Since 83803 is more suited for amps & sub woofers, I use this for Sub-woofer.

沙沙3號 之 派拉利 1.5mm 灌沙線

派拉利無味精 & high c/p! Some chings said, "派拉利 is 中性 & 無音染". This is not true. U need much time to run it in to realise its full potential. As a ching explained, "theoretically, 單支 is better than "multi-支" within one cable as 單支 prevent "cross talks" among conductors of multi-支!" 老板個老爹在LCDTV試過沙沙3號 MK I slim 版, 曾是電工的他驚訝說: " 正左好多!"

MK I:  派拉利 1.5 mm + (深)海底幼沙 + 碳粉
MK II: 派拉利 1.5 mm + 石英沙 + 碳粉
MK III: 派拉利 1.5 mm + teflon coating + VDH solution + (深)海底幼沙 + 碳粉
MK IV: 派拉利 1.5 mm + teflon coating + VDH solution + 澳門黑幼沙 + 碳粉 + 雙水喉

Noted: While PVC is a relatively inexpensive plastic, it only has moderate dielectric (insulating) properties—pass it up in favor of Teflon. From an electrical point of view, Teflon or it's generic types such as FEP or PTFE, are far superior.
