DIY your own high-grade power cord for Hifi use

You can make your own power cord. Just buy the wire and components and wire it up. Steps to do this are shown here. Disclaimer : if you wired up wrongly, you could smoke your equipment. Beware.

Components (all from LHS Electronics at Sim Lim Tower);
1. Belden 19364 power cord.
2. IEC connector (Choose a good brand, Hubbel, Wattage for example) The one I use is Marinco who OEM for other big brands.
3. MK hospital grade power plug.
4. 10 cm of heat shrink for the drain wire.
