Best DIY power cable. Why not make?


Ok perhaps I don't get it.  You have hot, neutral, ground and connectors.  I am looking for advise from those that have found the secret sauce in making power cables or at least those that have had great success.  With all the quality cable and connectors why not make your own?  I refuse to pay $2,000 plus for a power cable that would take a hour to build.  I am seeking your guidance and suggestions.  Thanks!

@czarivey,

Please do tell us which component in your setup currently powered by McMaster $10-$20 powercord.

Thank you for your time!
My new component will that will need a PC is the Lumin T1 Streamer/Dac power supply.
@goose,

The following components are required for a typical configuration of a LUMIN system:

- LUMIN Audiophile Network Media Player.
- iPad running LUMIN iPad App.
- Home Network including Wi-Fi connection.
- LUMIN L1 Music Server or NAS (Network Attached Storage) including a UPnP server (QNAP or Synology are recommended).
- Computer (optional) used for ripping CDs, downloading music and configuring the NAS.
- Amplifier and Loudspeakers.

You won’t need your existing preamp, PC and DAC anymore if you choose to get Lumin T1 and L1 music server.
