Aavik DAC D180

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-PSRR) 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 ground. This isolates the signal path from both potential ground noise and signal-induced ground modulation.
