STUTE & HENGST


True Digital / Analog Conversion System

31 January 2015 - New Product HENGST is released.

In 2010, Abendrot Audio was established as a high-end audio company by some of the world's most prominent engineers from the aerospace industry and leading designers from the audio industry. "Providing the very best in stereo sound reproduction": Here we provide a centennial milestone in audio history to realise this ultimate goal, with products developed through the master engineering of experts with more than 30 years of experience in designing various circuits that have almost transcended the limits of human capabilities. Our state of the art audio technology and continuous pursuit for perfection is certain to fulfill even the wildest dreams of seasoned audiophiles. Abendrot Audio products are designed by professionals from Japan and the UK, manufactured carefully and individually with the same level of expertise and precision perhaps previously only seen in the creation of ancient Japanese samurai swords, heightening our products to the level of art.

STUTE

 

True 10MHz Rubidium Master Clock

STUTE, our inaugural product, is a rubidium master clock that is certain to highly contribute to the advancement of high-end digital audio reproduction in the coming generations. Installed with the world's most accurate rubidium clock, only possible through the unique technology of Abendrot Audio, STUTE produces the 10MHz signal that is ideal for digital audio.

Prior to beginning the development of STUTE, Abendrot Audio conducted many surveys for the purpose of researching master clocks in the current market. Although a plethora of products were available at the time, it became clearer and clearer by the day that there were no rubidium master clocks developed with the precise expertise worthy for the world's most acclaimed high end audio systems, and we decided to take it upon ourselves to produce this much-needed apex product.

STUTE is designed by one of the most highly-acclaimed master clock engineers in the aerospace industry and is installed with a rubidium oscillator that has the accuracy of a single second difference every 1,000 years - an almost-perfect accuracy not possible by any existing products in the market. This ultimate master clock produces the most precise clock signal the industry has ever experienced, with near-perfect digital-analog conversion.

Abendrot Audio strongly believes STUTE is a monumental product capable of materialising all the ideals of digital audio. Our ultimate audio collection is certain to lead you into unprecedented boundaries way beyond the capabilities of existing analog and digital sound reproduction methods.

 

 

 

 

 

 

 

HENGST

 

True D/A Converter for STUTE

Abendrot Audio proudly announces the release of HENGST, a brand new D/A converter born after three years of intense development. HENGST has been created with the sole purpose of reproducing the purest audio sound possible.

The STUTE audio clock, highly acclaimed by audiophiles and audio professionals alike, provides the ultimately pure 10MHz external clock signal to the HENGST D/A converter which is designed to fully utilise this 10MHz signal and maintain maximum audio conversion quality. By completely separating the digital audio and clock signals sent from the AES/EBU SPDIF input, HENGST realises the conversion of pure digital audio to analog audio in conjunction with the almost-perfect clock signal generated by STUTE.

HENGST has been developed as the ultimate device for sound aiming for nothing less than perfection. The supreme mechanisms of HENGST are gauranteed to heighten your emotions through every moment of the 'sound' experience, from the fraction of silence right before the sound pours out into the air, all the way up to to the moment the rich and dynamic sound vanishes back into complete silence. HENGST materialises the subtlest of sound reproduction and its vast sound field produces sound clear enough to make you feel as if the artist was singing or playing his instrument right there in front of you. We strongly believe that we have been able to realise the genuine sound quality of high-end analog reproduction devices through our high precision digital audio technology.

With strong self confidence, we present HENGST, the only truly genuine D/A converter in the market, as an attractive product that challenges the technological boundaries of audio reproduction. HENGST redefines the pinnacle of audio reference, and is certain to bring new discoveries and add rich emotion to your digital music collection.
