24 BIT / 96 KHZ DIGITAL TO ANALOG CONVERTERS
The ALTMANN DA is a high performance digital to analog converter for professional and high-end audio applications. It is designed using the latest available technology, and implements a new approach of analog post-processing and output interface, resulting in ultra high speed line driving and unrivalled performance.
The ALTMANN DA implements the ASRS design topology which is capable to supply the most authentic and pleasing audio reproduction of the industry.
The ALTMANN DA is covered by a 5 years limited warranty.
AUTHENTIC SOUND REPRODUCTION SYSTEM (ASRS)
Since every gain device, by nature, injects a specific amount of distortion into the signal-chain, the output signal will be degraded to a specific extent.
A DAC chip may be seen as a gain device with exceptionally high distortion in general, and particularly with a high out of band distortion.
In all common DA converters, the - out of band part - of the generated distortion will partially be removed by analog post processing circuitry. The residual distortion is then ´glued´ inside the output signal and cannot be removed in following processing steps.
This residual distortion generates sonic artifacts, that prevent even the most advanced digital equipment to faithfully reproduce certain natural sound sources, such as: vocals, strings, horns/reeds, pianos, organs, acoustic & electric guitars, drums, etc.
Even today, recording engineers and large parts of the audiophile community complain about artifacts in digital sound reproduction, and there is a consistent tendency to use high quality analog equipment, whenever possible.
The ASRS design topology overcomes the limitations of all existing DAC systems by implementing proprietary filter elements, that remove distortions directly from the chip-surface of all gain devices, before the signal can leave the specific component.
This effective reduction of residual signal corruption promotes a perfectly authentic reproduction of all natural and synthetic sound sources, while maintaining an unrivalled level of overall performance.
The ASRS design topology is implemented into all ALTMANN DA models.
The ASRS design topology is a proprietary development by AMM.
