High-performance digital audio interconnect Before he founded Tributaries in 1991, owner Joe Perfito spent 15 years working for McIntosh Laboratory, Inc. Back then, he says, the concept of designing cables based on sound scientific principles was considered extremely radical. That became his company's mission, though, and it continues to produce audio cables designed to curtail distortion, deliver reliable tonal balance, and reduce the noise floor to near zero to bring your music to life with rich detail. The clearest signal transfer for your components with optical connections Use this cable for digital connections between compatible components - CD players, Blu-ray or DVD players, A/V receivers, DACs, and even some sound bars - and you'll get transparent, articulate signal transfer for great-sounding music and soundtrack audio. Cables made of wire require a metal-to-metal connection to transfer the signal between components. Optical cables carry signals as pulses of light rather than a stream of electrons. That means they're virtually impervious to magnetic or electrical interference. This cable uses a 1mm crystal-clear fiber core, and the connectors are the polished ends of the fiber itself. The "lenses" of this cable are machine-polished to reduce light refractions, so it can deliver your music with clear, uncolored brilliance.
