Dear Audiophiles,

     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. Ulta wide bandwidth coax cable (digital signals opperate 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 instrumentaion 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 impedence. Closest in the industry, as a matter of fact. The Canary 75 ohm RCA connectors are not 75 ohms, just call and ask their engineers. 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.

This cable is priced at $400 for one meter. Additional length is $50 per meter. This is a bargain in this industry. Considering how much time and effort went into design as well as the exotic/specific parts it requires. There are cables costing 10 times more that don't come close to the performance of Nagys Audio cables. Real engineering makes a difference.

Rather than tell us to contact Canare to ask why their connectors are not 75 Ohm, why not tell us how you determine the impedence of your rca connectors to get some discussion going?

Put a 75 ohm load on the RCA connector, send high frequency waves and measure how much they reflect.

That's a bit obvious, what is the theory as too why?

This is a phenomena that happens only at higher frequencies. In consumer products the load is 75 ohms and in military it's 50 ohms. So, when you have a cable that goes from your transport to DAC, everything must be 75 ohms, this includes the female RCA connectors, male RCA connectors and the coax cable itself. If one of these components is not true 75 ohms part of the signal will reflect, but only at high frequencies, like the ones digital signals are transmitted in. If the cable it 75 ohms and the connector is 70 ohms only a small fraction will reflect, however if the cable is 75 ohms and the RCA is 50 ohms (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 30-55 ohms. At high frequencies, the shape of the connector and the thickness of dielectric will determine the impedence. That is why it's so hard to make RCA connectors 75 ohms, their shape and conductor spacing prevent this. BNC connectors are a different story, they can easily be made to be 75 ohms.

Also, our digital cables feature dual shields. Foil shield to reject RF noise and braided shield to reject EMI. For a 100% coverage.
