ToneWinner GQ-2 is a Toslink optical cable for passing a digital S/PDIF audio stream from a television, game console, disc player or streamer into a DAC, soundbar, amplifier or surround receiver. Optical transmission keeps the two devices electrically isolated, so the connection cannot introduce a ground loop.
Key specs that matter
The fiber core is made of polymethyl methacrylate (PMMA). Length is 1.5 m, the jacket is black, and it is sold as one cable.
Alternatives
The ToneWinner GQ-6 is a second Toslink optical model in the brand's cable range.
