Egenskaper
Analog, warm and detailed
The D-180 DAC is handling the enormous amount of information contained in the digital source to a natural, warm yet detailed soundstage.
Analog signature.
Our ultimate goal in developing the Aavik DACs has been to transfer the digital signals into a natural, harmonious, yet, dynamic music experience without losing any of the enormous amount of information contained in the digital source. Our engineers have been extremely fastidious in selecting the electronic components and have spared no effort to exploit any opportunity for acoustic improvement.
The DAC section
Secure the signal transport and the tonal balance.
The Aavik DAC section is designed around 5 digital inputs, which all excel in audio performance. The DAC operates without any digital signature. This makes any music sound natural and authentic. The digital circuits boast the best high frequency capacities and great care was devoted to the set-up of the *PCB design. By employing time-aligned, ultra-short, 4-layer *PCB traces, Aavik wants to preserve the natural and pristine sound quality of the wide and complex range of different signals. The DAC circuits are also fitted with ultra-low jitter onboard clocks. To minimize timing errors in the digital-to-analogue conversion, all DAC circuits are isolated with 13 onboard, separate, low-noise, **high-PSSR voltage regulators, each feeding only one stage of the signal handling. The USB input is galvanically isolated to avoid noise pollution from the host. The digital inputs are routed to an ***ASRC, where they are re-sampled and re-clocked to 200 kHz/24 bit PCM, feeding current output DAC chips. For the current-to-voltage conversion, Aavik uses a differential floating topology with virtual ****GND. This isolates the signal path from both potential GND noise and signal-induced GND modulation.
