ToneWinner AC-1 is a stereo RCA to RCA analog interconnect that the maker lists among its entry-level signal cables. It connects sources, DACs and preamplifiers to amplifiers or receivers over unbalanced line-level links.
Key specs that matter
Its 5N OFC oxygen-free copper conductors are specified at 99.999% purity. The cable is 1 m long, finished in black, and terminated with 24K gold-plated non-magnetic RCA plugs.
Engineering and use context
Shielding is layered. A thick aluminum foil wrap sits under a high-density braided net made of 5N oxygen-free copper, and an electromagnetic shielding ring of special material is added as well. ToneWinner presents this construction as protection against radiated interference and noise from nearby devices.
Alternatives
The ToneWinner AC-6 sits above it in the same interconnect range and uses 6N OCC single crystal copper conductors.
