Ascent Ultra S/PDIF

The Atlas Ascent Ultra 75 Ohm SP-DIF digital cable is a superb cable which gives a considerable insight into the state-of-the-art performance of our ‘high-end’ Mavros interconnect at a very reasonable price. Ascent was designed to be technically and sonically superior to competing digital cables currently available at similar prices.

Designed to maintain a true 75 Ohm impedance.

The central conductor is made from OCC copper which is insulated by an extremely low-loss PEF (Foamed Polyethylene) dielectric. The tightly woven wire mesh together with an aluminium outer foil provides 100% rejection of RFI (Radio Frequency Interference) ensuring the music signal is free from any external noise. The cable is covered by a soft PVC sleeve and finished in a grey woven fabric.

The Ascent digital cable is terminated with our cold-weld connected wideband Ultra RCA plugs. The result is a smooth, uninterrupted signal path which behaves as one continuous entity, with minimal degradation of the signal compared to soldered connections. This is particularly important in a digital cable, connectors which compress the cable can actually alter the cable’s impedance, which drops below the 75 Ohm specification, typically by up to 50%, reducing accuracy of the signal transfer.

    Ascent Ultra S/PDIF

    The Atlas Ascent Ultra is, in my opinion, an essential addition to any digital-sourced hi-fi system.

    When a single cable can manipulate, modify and refocus your music in this way then the ‘mere’ £175 (and I’ve seen it a lot cheaper than that on the Internet) can be viewed as true value for money.
