What's in the box
Written by Crutchfield's Steve Kindig
Thanks to HDMI, optical connections between components are no longer as common as they used to be. But you'll still find Toslink connectors on CD and Blu-ray players, cable and satellite boxes, TVs, sound bars, and more.
AudioQuest has refined their line of high performance OptiLink cables, starting with Pearl. Pearl is AQ's most affordable Toslink cable, but it's been carefully engineered to provide a distortion-free connection whether you're feeding stereo music to a DAC or Dolby® Digital surround sound to your A/V receiver.
Optical cables carry signals as pulses of light rather than a stream of electrons, so they are virtually impervious to magnetic or electrical interference.
