The ultra precision technology that we use in our interconnect 
    cables is now incorporated into our latest digital cable design. 

    This is a digital cable by which all others are judged. 

    Painstakingly hand crafted by real engineers, engineers who 
    hold Ph.D degrees in electronic science with 30+ year experience. 
    Some of which includes engineering technology for Russian 
    submarines and fighter jets.

    This cable will be your ultra link of transporting digital data. 
    It will preserve the signal to the very last micro bit of information. 

  Key Considerations During the Design Phase

    1.  Ultra wide bandwidth coax cable (digital signals operate at 
         higher frequencies), with Teflon insulated conductor. 

         Teflon is arguably the best dielectric one can use in a cable, 
         although Kapton comes pretty close, taking everything into 
         consideration. 

         All precision instrumentation or military equipment use Teflon 
         and Kapton, sometimes both in combination. 

         This solves a lot of the phase and time distortion, jitter, etc. 
         Square waves actually look like squares and they are not 
         shifted (not in phase). 

         How does this translate into sound? Life like! 

         Dynamic range increases and transient response becomes 
         much faster.

    2. Precision RCA connectors, extremely close to 75 ohm 
        impedance. Closest in the industry, as a matter of fact. 
        75 ohm RCA connector prevent signal reflections, which 
        would ruin everything covered above.

    3. Unique attachment of RCA connectors to coax cable, in two 
        separate parts. One is a pressure fit and the other is soldered 
        using a proprietary technique, with specific solder made 
        especially for precision instrumentation electronics. 

        Having a good connection between the cable and connector is 
        critical, otherwise all sorts of impedance accidents and 
        reflections could occur and ruin everything in steps 1 and 2.

    Real engineering makes a difference!

  RCA Impedance

    This is a phenomena that happens only at higher frequencies. 

    In consumer products the load is 75 ohm and in military it's 50 ohm. 
    So, when you have a cable that goes from your transport to DAC, 
    everything must be 75 ohm, this includes the female RCA connectors, 
    male RCA connectors and the coax cable itself. 

    If one of these components is not true 75 ohm part of the signal will 
    reflect, but only at high frequencies, like the ones digital signals are 
    transmitted in. 

    If the cable it 75 ohm and the connector is 70 ohm only a small 
    fraction will reflect, however if the cable is 75 ohm and the RCA is 
    40 ohm (which is typical for most expensive/fancy so called audiophile 
    RCA connectors out there) significant part of the signal will reflect. 

    First, this reflection makes the signal weaker and second, the  
    reflection can cause an avalanche effect where it disturbs the signals  
    behind it. 

    This is all very bad for an instrumentation type cable.

    Most RCA connectors are 40 ohm. At high frequencies, the 
    shape of the connector and the thickness of dielectric will determine
    the impedance. That is why it's so hard to make RCA connectors 75
    ohm, their shape and conductor spacing prevent this. BNC connectors
    are a different story, they can easily be made to be 75 ohm.

    Our digital cables feature braided shields to reject EMI (electro- 
    magnetic interference).
