Synergistic Research AC Master Coupler X2 AC cord. 5ft 15amp version. Former DEMO pc. $675 MSRP.

Stereophile recommended AC cord for basically any components. Affordable AC cord upgrade that will bring about a nice improvement over stock cord and one of the best upgrade options for under $300 now. Cables look good for its age, just minor scuff marks/stains here and there. Cable was a former DEMO piece so the label states it as such. Wall wart power supply has two available prongs so it can be used with another Synergistic Research AC cord if you find one and want to run it through the same power supply.
