I accept the challenge. Here are 12 reasons why certain power cords could sound better than others.
1. Higher purity metal (oxygen free, 6 nines, etc.)
2. Higher conductivity metal, I.e., silver
3. Better dielectric material
4. Solid core vs stranded conductor
5. More effective shielding
6. More effective plugs (e.g., better conductors, tighter connection)
7. Conductor wires and strands controlled for directionality
8. Conductors are long crystal copper
9. Solid core metal wires are highly polished
10. Power cord cryogenically treated
11. Thicker conductor
12. Dielectric bias system
