  DH-Labs Silver Sonic D-750 Digital cable

  The new Silver Sonic D-750 is an ultra-low loss digital coaxial cable that has been engineered to deliver precision 75 ohm signal transmission. It replaces the popular D-75 and improves upon that cable’s well-regarded ability to accurately transmit today’s complex and sensitive digital signals. The most common use for this cable is to connect the digital output of a CD or DVD transport to an outboard Digital to Analog converter or other processor. Several features built into this product make it superior for digital audio use.

  A solid, silver-coated center conductor is used to maintain the most uniform impedance. A solid conductor minimizes signal reflections, a characteristic that is crucial to accurate digital data transmission. This center conductor is encased in DH Labs’ proprietary Air-PTFE Matrix dielectric, featuring an astonishingly low dielectric constant of 1.4. This material yields the lowest loss and most uniform attenuation versus frequency curve of any dielectric material.

  Noise rejection is maximized by a 2 Layer shield. This provides 100% coverage for complete noise immunity. The combination of an aluminum Mylar shield and a heavy braid keeps ground resistance as low as possible. The braid is precision wound with carefully controlled tension to minimize a phenomenon called “VSWR spikes”, more commonly referred to as jitter.

  The result of these efforts is a cable that delivers precise signal transmission with optimal balance and superior dynamics to well beyond 2 Gigahertz. The D-750 is available in bulk, or skillfully hand-terminated with our matching coaxial RCA-750 connector. For maximum performance, 75 ohm BNC connectors are also available.

  Continuing with the DH Labs tradition of providing maximum value, the D-750 costs much less than its superior performance level would suggest.

  USB

  The new DH Labs USB cable continues our tradition of offering state-of-the-art digital audio cables at affordable prices. As with our other digital cables, our new USB cable combines top quality materials with precision manufacturing and solid engineering. Although the USB interface is very different from the S/PDIF and AES/EBU interfaces, the requirements for a good USB cable are similar to those for conventional digital cables. We start with silver-coated OFHC copper conductors, and we insulate them in a low-density gas-injected dielectric. The combination of these two materials provides a more uniform attenuation vs frequency curve, which helps to preserve waveform shapes at the Megahertz frequencies where digital cables operate. At these frequencies, it is very important to maintain the very tight control over the insulation thickness, and we also cable (twist) the conductors on a machine that runs slowly and with uniform (constant) tension. These techniques combine to maintain a highly uniform characteristic impedance, which minimize signal reflections (and thus cable induced jitter). At Megahertz (and Gigahertz) frequencies, cables behave as wave guides. Dimensional discontinuities - such as inconsistencies in insulation thickness or non-uniform spacing between the conductors - are a major reason for poor digital cable performance. Finally, we use 100% shield coverage (the shield is also wrapped at constant tension, to avoid "VSWR spikes") and top quality connectors.
