Antelope Audio will introduce the Rubicon, a groundbreaking 384 kHz digital audio preamplifier which integrates the world renowned 10M Rubidium atomic clock during the Munich High End Show, May 3rd – 6th. Rubicon caters for the ever-increasing interest in high resolution audio, addressing the specific needs of high end consumer electronics enthusiasts for accurate audio representation and detailed soundstage of both analog and digital recordings.

Rubicon is the first DAC to integrate a Rubidium atomic clock, which is 100,000 times more stable than a traditional crystal oscillator. Coupled with Antelope’s 64-bit Acoustically Focused Clocking technology, the Rubidium achieves a breakthrough in jitter management, improving the sound quality in an unprecedented way. The same technology is implemented in the company’s flagship master clocks used for scoring blockbusters such as Avatar and available at the best recording and mastering studios around the globe.

Housed in a sturdy, machined-aluminum enclosure with a vintage Art Deco design, Rubicon incorporates a discrete phono preamp, ultra linear, dual stage headphone drivers and Antelope’s renowned gold-plated relay volume control.

The transformer-based, ultra-low noise, discrete JFET phono preamp is a complement that will be highly appreciated by many vinyl lovers.  In addition to the 384 kHz DAC, Rubicon also includes ultra-high sample rate A/D conversion. These functionalities together with the high resolution USB recording capability provide the users with the sublime experience of digitizing their favorite tracks, still keeping the depth and the warmth of the original analog recordings.

In addition to the 384 kHz USB streaming, Rubicon offers extended flexibility and smooth user experience provided by the implemented DLNA capability. The DLNA streaming gives users the opportunity to wirelessly push audio files from their smart phone, PC or NAS (Network-attached storage) server and play the content through the high-sample rate DAC.

Rubicon inherits the D/A conversion technology from 384 kHz Zodiac Gold DAC – the 2012 winner of the Audio Excellence Award in Japan and often described by reviewers and prominent sound engineers as “future-proofed”,  “clean”, “neutral” and “accurate”. The A/D circuit comes from the 2011 winner of the Audio Media Gear of the Year award, high-end professional mastering converter Eclipse 384.
