Atomic gadgets: world’s first atomic AD/DA preamp


Antelope Audio, the manufacturer of state-of-the-art, high-end devices addressing the demands of the most discerning listeners, introduced Rubicon, world’s first Atomic AD/DA Preamp, a sophisticated 384 kHz digital audio preamplifier which integrates the world renowned 10M Rubidium atomic clock.

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,” said Antelope Audio in a press release.

The same technology is implemented in the Antelope’s flagship master clocks used for scoring blockbusters such as Avatar and available at the best recording and mastering studios around the globe.

“I find the idea of an audio enthusiast being able to hear his/her favorite recordings clocked by the world’s most stable clock very exciting. I believe this will bring the music appreciation in the home environment to a completely new level compared only to the precision and sonic detail representation available at the finest professional listening rooms,” shared Igor Levin, CEO and founder of Antelope Audio.

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.
