STUTE

 

True Audio Master Clock Generator STUTE, our inaugural product, is a rubidium master clock designed specifically for apex digital audio systems. Through the exclusive technology of Abendrot, STUTE produces the coveted 10MHz signal ideal for digital audio. Combining our expertise with layers and layers of logic and development, some of the most highly-acclaimed and passionate master clock engineers in the world focused on the almost impossible task of reproducing a near-perfect time axis, an integral factor in realising the ultimate digital reproduction experience, which is now known as STUTE. Abendrot strongly believes STUTE is a monumental product perhaps finally capable of materialising the ultimate ideal for digital audio: To supersede the qualities of analog reproduction. This ultimate master clock produces the most precise and sophisticated clock signal the industry has ever experienced, with near-perfect digital-analog conversion. Our ultimate audio collection is certain to lead you into unprecedented boundaries way beyond the capabilities of existing analog and digital sound reproduction methods, bringing those blissful moments from a concert hall to within the walls of your private audio room.

 

 

 

HENGST

 

True D/A Converter for STUTE

Abendrot proudly announces the release of HENGST, a brand new D/A converter born through over three years of intense development with the sole purpose of reproducing the purest audio sound possible. With new technology transfuse clocking of Abendrot, HENGST is optimally designed to maintain the audio conversion quality received through STUTE's almost perfect 10MHz signal. By completely separating the digital audio and clock signals sent from the AES/EBU and S/PDIF inputs, HENGST realises the conversion of pure digital audio to analog audio. The articulate and strikingly expressive characteristics of HENGST are guaranteed 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 when the rich and dynamic sound vanishes back into complete silence, vastly heightening every sense of your emotion in the process. We strongly believe that we have been able to realise the timeless sound quality of high-end analog reproduction devices through our high precision digital audio technology. With strong self confidence we present HENGST, a cutting-edge D/A converter that challenges all technological boundaries to redefine the pinnacle of audio reference. HENGST is certain to bring new discoveries and add rich emotion to your digital music collection.
