Hemingway Z-Core Beta power cable for sale. Minor blemishes on the FMCF module, but the connectors and the cable have no flaws. It's the quietest power cord I've ever experienced in my very transparent horn based high efficiency system.
Price new: $4800 2m
Asking: $1650 (firm)
From the review
https://www.soundstageultra.com/index.php/equipment-menu/1054-hemingway-audio-cable-z-core-alpha-beta-and-sigma-power-cords description:
"—patented in South Korea by Hemingway and developed over a 13-year period—called Frequency Modulation Cavity Fundamentals (FMCF), which is designed to convert RFI and EMI into magnetic energy. According to Chung, this conversion is accomplished via a spherical gold-plated network device that in the case of a power cord is placed over the conductors, about 7″ from the male connector. The company claims the conversion alters the conductors’ resistance, dramatically reducing noise and sonic artifacts."
Price is firm. Buyer pays $25 flat rate shipping anywhere within US. Pick up from Brooklyn, 11205 is welcome.
