Found this info from the manufacturer of the cable from Audio Sensibilities.
"The Lumin X1 power supply (PSU) provides five independent DC rails of power (one high current, four lower current). The Lumin X1 power supply cable uses top grade 10 pin Japanese DC connectors. All 10 pins of the connector are used with the required five twisted pairs of wire.
Like all high-end equipment manufacturers, Lumin provides very basic AC and DC power cables with the X1. This keeps the base cost of the X1 as low as possible. The customer can then independently decide if they wish to upgrade either of the stock cables.
The stock Lumin DC cable uses PVC insulated tough pitch copper (TPC) which is of a lower grade than OFC (better) or OCC (best) copper. Estimated cost is $2.00/m.
The Audio Sensibility DC cable uses cryogenically treated Teflon insulated OCC silver. This is the same OCC silver used in premium audio cables such as the Wireworld Platinum Eclipse 8 line.
OCC silver is very expensive and is the primary material cost of our cables. The Japanese DC connectors are also not inexpensive.
BTW: For this DC cable we are currently using Neotech solid core OCC silver wire. Wire use is 115% of the stated length of the cable."

The DIY parts alone add up to 2/3 of the price of the AS X1 DC cable.
