Great performance and value Lots of audiophiles feel that digital coaxial cables perform better than optical cables in demanding systems. And when it comes to high-resolution audio, coaxial connections support audio transfer all the way up to 24-bit/192kHz, while optical connections are usually limited to 24-bit/96kHz. We've also noticed a recent trend of some Blu-ray players including a coaxial digital out, but no optical. Anyone looking for a high-performance digital coax cable that's also reasonably priced should consider Monster's 400dcx2. Ideal for stereo and surround sound Whether you're connecting surround sound sources like a cable/satellite box or Blu-ray player to your home theater receiver, or hooking up an old CD player to a new outboard DAC, Monster's 400dcx2 will keep those digital bits flowing correctly. Working from the inside out, Monster starts with a high-purity solid-core copper conductor, surrounds it with a special gas-injected dielectric material for low signal loss, then wraps that in a 100% foil shield to suppress external noise sources that can harm audio clarity. Product highlights: solid-core copper center conductor gas-injected dielectric for low-loss signal transfer, even over long runs or when cable is bent 100% foil shield rejects noise and interference patented 24k gold contact 6-cut Turbine® RCA connectors with split-tip center pin for a reliably snug fit Duraflex® protective jacket is extremely flexible for easy routing and installation warranty: lifetime
