Aavik D-280 Reference DAC

0.00 inc V.A.T.

Digital To Analog Converter

Aavik鈥檚 ultimate goal in developing their separate DAC models 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. To reach this goal, Aavik鈥檚 engineers have been extremely fastidious in selecting the electronic components and have spared no effort to exploit any opportunity for acoustic improvement.

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 aims 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 minimise timing errors in the digital-to-analogue conversion, all DAC circuits are isolated with 13 onboard, separate, low-noise, high PSRR (power supply rejection ratio) 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 Asynchronous Sample Rate Converter, where they are re-sampled and re-clocked to 200 kHz/24 bit Pulse Code Modulation, 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.

To best accommodate individual listening preferences, and fit hand in glove into your existing audio system, Aavik has designed 4 individual settings. Since the selected signal source connected to the input can tinge the actual sound performance, up-sampling can be switched on and off. There is also a choice between a slow (soft high-frequency roll-off) and a fast (steep high-frequency roll-off) filter.

The D-280 is the second model in the Aavik DAC range and offers exceptional performance, sharing much of its DNA & technology with the state-of-the-art D-580. It contains significant noise reduction technology that results in a black ultra-quiet background from which micro details emerge with great clarity and resolution. It delivers a world class audiophile sound that has a level of articulation and liquidity that defies belief. Looking for a destination DAC that will surpass expectations?

Unique Technology

PREMIUM TECHNOLOGIES FOR UNCONSTRAINED SIGNAL FLOW

Aavik collaborate with their sister company, Ansuz-Acoustics鈩 and draw on their experience and extensive R&D in the fields of resonance control and noise cancelling technologies. Aavik have fitted all of their streamer models with with Tesla coils, dither circuitry and anti aerial resonance coils. These innovative technologies are geared towards paving the way for an absolutely unconstrained signal flow. Aavik has also prepared the top and bottom surfaces on all the servers to accommodate the Ansuz Darkz鈩, which represent the most effective way of preventing mechanical vibrations.

RESONANT MODE POWER SUPPLY 鈥 QUIET BUT EXTREMELY POWERFUL

The new Aavik series is designed to ensure massive power resources with ultra-low noise. Unlike the square waves used by conventional switch mode power supplies, the new Aavik series boast a resonant mode design which is principally driven by sine waves. When more power is needed, the operating frequency increases, which, in turn, has the advantage that the power density also increases, thus allowing higher peak power when required by the music.
The noise floor in the raw power supply is extremely low but could be even further lowered by the ultra-low noise regulators supplying the different parts of the circuit. The noise of these regulators is measured in a few microvolts respectively nanovolts, which is significantly lower than the noise level of conventional regulators.

SCANDINAVIAN DESIGN AESTHETIC

The Aavik design language is Scandinavian understatement and expresses simplicity and minimalism featuring only a few buttons for logical operation. The multifunctional main knob allows simple navigation and control of the various functions. A distinguishing design feature of the new Aavik series is a huge red display, which makes it easy to read all details of the selected operational settings.

A CABINET WITH EXCELLENT SONIC QUALITIES

Aavik have designed the enclosure to minimise the use of aluminium and its associated mechanical resonance. Over the years, Aavik have been testing various materials and ultimately designed an innovative natural-based composite material, which reduces the mechanical influence, particularly the hysteresis. The sonic result is distinctly audible and reflects a further prominent cornerstone in Aavik鈥檚 quest for the ultimate music experience.

The Aavik DAC Range

Aavik have produced 3 levels of performance within the acclaimed D-180, D-280 and D-580. The D-180 represents great value with a high-end performance capability beyond its price level. The D-280 adds significantly more resonance control techologies resulting in an even lower noise floor, resolution and accuracy. The D-580 introduces the unique copper inner chassis, Titanium level resonance control, and the maximum Ansuz Acoustics resonance mitigation technology, taking performance to a statement level.
