WADAX ATLANTIS DAC NUOVO

WADAX has been improving D/A technology and performance for the last 10 years: lowering the noise floor, increasing temporal and detail resolution, reducing the ‘footprint’ left by digital artefacts in the recording. The result has brought digital playback closer to live performance than ever before.

WADAX has been improving D/A technology and performance for the last 10 years: lowering the noise floor, increasing temporal and detail resolution, reducing the ‘footprint’ left by digital artefacts in the recording. The result has brought digital playback closer to live performance than ever before. Fed back into our Fundamental Research Program, these performance improvements have revealed that, once the noise and error levels across the circuit blocks are reduced below a certain point - and in reaching that point, the original Atlantis DAC already surpasses all of the competition - the human auditory system becomes capable of far higher resolution, allowing us to perceive clocking errors, PSU interference and the effects of mechanical vibration that were always present but previously masked. The Atlantis REFERENCE DAC is our response to these findings, with lower levels of clock noise and significant improvements in PSU and mechanical isolation. The result is a masterpiece. The result is the most accurate and most musically satisfying DAC ever designed.Everything about the Atlantis REFERENCE DAC is unique to this product: the clock circuitry; PSU topology and distributed regulation; the implementation of the musIC feed-forward error correction technology; the totally independent, dual-Mono DAC and analog circuitry; the fully modular construction, allowing for future upgrades or updates of key circuit blocks; the physical separation and independent housing of left and right channels, left and right channel power supplies; the mechanical vibration management incorporated in the chassis construction – and that barely scratches the surface of a product that contains 23 printed circuit boards, 10 independent, purpose-wound power transformers and over 5,500 discrete parts…The unique musIC Feed-forward Error Correction Process Conventional digital decoding struggles to achieve its theoretical performance: components and circuits never behave ideally, generating a complex, polluting mix of non-linearities that contaminates the delicate audio signals during and AFTER conversion. The delicate micro-information and expressive nuances in the musical signal are obscured by inter-reactions between power supplies, clocking, grounding, analog circuitry and the digital to analogue converter. To further complicate things, these non-linearities and error mechanisms are load dependent, varying with signal amplitude. Together they form the core of what we have all come to recognize as “digital sound.” Wadax technology is founded on the unique musIC process, a sophisticated feed-forward error correction system that operates in the time domain. By mapping the error mechanisms of a chosen DAC chip under load using Adaptive Delta Hilbert Mapping, we can develop an algorithmic that examines the incoming signal and calculates the induced error (both linear and non-linear) that will result. By applying an inverse signal at the input we can real-time correct for the time and phase error that is so musically destructive in other, conventional decoding systems. This process requires a massive number of mathematical operations and considerable datatransfer: 12,8 GBytes/s. Processing is done at 128 bit internal resolution to precisely render the output and generate the smallest feed-forward corrections. The result is measurably and audibly the most natural and musically communicative digital decoding currently possible – something that’s obvious as soon as you hear the Atlantis REFERENCE DAC. - 23 individual printed circuit boards - More than 5500 discrete parts - Dual-differential musIC 3 128-bit-feed-forward error correction process - Fully balanced, dual mono design with complete physical and electrical separation of left and right channels - 10 purpose-wound, functionally specific power transformers - Digital circuitry time aligned to 100ps - 0.5uV of total rail noise (1Hz-100KHz): ultra sophisticated power supply with distributed regulation topology. - 30 local regulation stages, 5 stages of DC regulation. - User-adjustable gain and output impedance. - Zepto Reference clock: doubled the master clock frequency with only 12fs total jitter.
