QED’s Reference Digital Audio 40 Lead-Establish is a very good digital audio cable that improves sound quality. It is designed to connect audio systems. Such as CD players, DACS, Blu-ray players, and amplifiers and receivers. Usually, the best audio products are in the latter group.
QED Reference Digital Audio 40 Lead
The QED Reference Digital Audio 40 Lead uses a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals.
Silver-plated conductors deliver a low-resistance path for high frequencies. The QED Digiloc2 plugs more closely match the cable’s characteristic impedance. Reducing return loss by up to 1.5 db compared to conventional RCA plugs. This ensures optimal signal transfer and improves audio signal micro-timing.
Delivery of Superior Digital Audio Signals
Silver-plated signal carriers, effective high-quality shielding, and impedance-matched cordage. And plugs all combine to create audible sonic improvements compared to the competition.
Triple Layer Electromagnetic Shielding
By implementing factory-controlled geometry and low permittivity foamed polyethylene dielectrics. The Reference Digital Audio 40 lead maintains the correct characteristic impedance to precisely match the transmission line between the digital source and sink. This makes for a very low jitter signal transfer, which, listening tests have shown. Leads to clearly audible sonic improvements.
Impedance-matched Digiloc2 RCA plugs
Domestic S/PDIF output makes use of the traditional RCA phono connector. Which is not impedance matched to the 75 Ohm transmission line. This results in the insertion loss that can be physically measured and an increase in jitter due to signal reflections at the connector boundaries.
The new Digiloc RCA plugs will be even more closely impedance matched than prior models and test results indicate that they can reduce the insertion loss by as much as 1.2 dB in comparison with standard RCA plugs.
Triple Layer Electromagnetic Shielding
Electromagnetic triple layer shielding consists of a double layer closely woven 99.999% OFC shield braid and an aluminium mylar wrap with 100% coverage. Which are coaxially spaced around the central signal carrier within a foamed polyethylene dielectric.
This arrangement guarantees that signals of interference induced by nearby high current noise sources will not produce a higher level of jitter of the signal than in the normal situation. In addition, the shielding will bar unwanted voltage induced interference from escaping the cable that could otherwise affect nearby analogue signal carriers.
The all-new Digiloc2 design substitutes high-rigidity thermoplastic material for the inner support structure. Plus, the Reference Digital 40 cable strain relief to eliminate the distorting effects of eddy currents. Which are always present in ordinary plugs where bulk brass is used instead.

QED’s Lead to the Future with Digital Audio 40
The triple layers of electromagnetic shielding are made up of a dual layer closely woven 99.999% OFC shield braid and aluminium mylar wrap with 100% coverage. all arranged coaxially around the central signal carrier within the foamed polyethylene dielectric.
Thus, any interference signals arising from nearby high current noise sources that get into the cable will not result in increased signal jitter. Similarly, the shielding stops any undesired voltage induced interference that could be escaping the cable and affecting neighboring analogue signal carriers.
Superior Resistance to Mechanical Damage
The QED Analoc plug is designed with a very low eddy current structure. It replaces the large volume brass body, which is typical in ordinary high-quality plugs. With small segments of high purity copper as the conductors. This greatly reduces or completely gets rid of the problem of the changing magnetic field in the conductor. Giving rise to eddy currents which can alter the micro-timing of the audio signal.
Great User-Friendly Features
Besides offering supreme audio reproduction. It is also very suitable and handy to your regular sound requirements. The perfectly molded connectors are very easy to plug or unplug without damaging the cable or the device. Being able to harness the full capabilities of the cable makes it suitable for a single room as well as a complex apartment thorough installation.
