Here is an interview with Igor Levin published by Audio Times in 2012. Igor answers questions about some critical aspects of A/D and D/A converters and master clocks design.
 
Irrespective of the sampling rate, what are the really important elements within successful A/D and D/A converters designs?
About 20 years ago when I built my first D/A converter I had also to build a clock for it. At that time, clocks were not something that you just go out and buy. So I built my first clock for my first D/A converter. People liked the converter, but what they really appreciated was the clock. This was when I realized the importance of the stable clocking reference for digital audio.
 
I still believe the accurate clock is the basis for successful conversion. In fact as the chips get better and the circuit artifacts we struggled to overcome fall away, the significance of good clocking has come to the fore as never before. Today I would say it amounts to at least 75% of the overall sound. Of course there is a list of other important factors such as proper layout, stable power supply, the analog-based volume control etc.

CES 203 2013 Innovations Honoree

Санта-Моника, Калифорния, 13 ноября 2012 – Сегодня представители Antelope Audio объявили, что компания получила одну из самых престижных наград – CES Innovations Design and Engineering Awards 2013 на Международной выставке потребительской электроники (CES) за Rubicon, новейший 384 кГц цифровой аудио предусилитель, в который интегрированы рубидиевые атомные часы 10 МГц. Престижная премия присуждается группой независимых экспертов, выдающихся промышленных дизайнеров, инженеров и представителей СМИ, в нескольких различных категориях продуктов потребительской электроники. Премии удостаиваются самые передовые продукты с лучшим дизайном и техническими характеристиками.
 
Rubicon стал ответом Antelope Audio на возрастающий интерес потребителей к аудио высокого разрешения. В нем учтены все потребности энтузиастов высокотехнологичной пользовательской электроники в точном построении звука и подробной «звуковой сцене» при воспроизведении как аналоговых, так и цифровых записей. «Rubicon» – первый предусилитель с ЦАП, имеющий рубидиевые атомные часы, точность которых по сравнению с обычным кварцевым генератором увеличилась в 100000 раз.
 
«Это невероятная честь – получить премию CES Innovations Design и Engineering Awards», – заявил Игорь Левин, генеральный директор и основатель Antelope Audio. «Рубикон, безусловно, стал выдающимся инженерным решением и для нашей компании, и, что более важно, для потребителей, так как он значительно улучшает общее звучание».

Luna – Eclipse 384 Remote Control Prototype Also to be Unveiled at the International Music Business Fair

 

Frankfurt, Germany, March 16, 2012 — Antelope Audio will demonstrate its professional-grade 384 kHz A/D and D/A converter, master clock and monitoring controller at Musikmesse 2012 in Frankfurt between March 21st and March 24th at the Exhibition center in Hall 5.1, Stand C 55.

 

The Eclipse 384 is the first multifunctional audio device capable of providing 384 kHz A/D and D/A conversion clocked by Antelope’s 64-bit technology and powerful, flexible monitoring control. Previously, the Eclipse 384 won both the “Best of Show” and “Gear of the Year” awards from two highly respected industry publications shortly after its launch last October.

 

The upcoming Eclipse 384 remote control – Luna will be demonstrated in prototype form at the Musikmesse. It provides users with a flexible way of placing key aspects of the Eclipse 384 within reach of any listening position. With the exact same functions featured on the front of the Eclipse 384, Luna enables sound engineers to easily control the device while sitting in front of the console.
