Aavik Unveils Latest U-Series Integrated DAC/ Amps
Aavik has expanded its range of integrated amplifiers and DACs with the new U-180, U-280 and U-580.
The new Aavik U-series components combine the integrated amplifier and DAC (the Aavik I and D 180,280 and 580, respectively) into one unit following on from the success of the U-150 and U-380 before them.
We are told that the Danish company has replaced the two original separate boards with a single redesigned mainboard and created the shortest possible signal path between amplifier and DAC.
The U-series shares the same basic DNA as Aavik's series of separates and is equipped with the same advanced electronic components and made from the same innovative materials.
The flagship Aavik U-580 is easily recognisable in no small part due to the large titanium brace inlaid in the top plate that's said to control resonance. Meanwhile, the inner chassis is made of solid copper. This premium series is also equipped with additional “Ansuz noise reduction control”.
Aavik says that this new series of components is designed to ensure massive power resources with ultra-low noise, which is apparently achieved through specially chosen regulators.
Noise reduction is the main differentiator between the three new models, as shown in the following chart.
Naturally, the Danish high-end company has also called upon its patented UMAC amplifier technology for the new U trio's 2x300W @ 8ohm units. This technology was developed to mitigate against the flaws of regular switching amplifiers and primarily focuses on two areas of modulated amplifier design.
Firstly, the PWM (PMW: Pulse-Width Modulation) generation is produced with sine wave modulation rather than the more common triangle modulation, which Aavik says “require far less inductive filtering at the output”. According to the manufacturer, the lower inductance in the output gives the amplifiers a much better damping factor and distinctly better speaker control. Secondly, the advanced dual mixed-mode feedback allows damping factors “characteristic of the very best linear amplifiers”.
Finally, the DAC section fed by a pair of BNC, brace of optical, and single USB input is said to operate without any digital signature. Additionally, only digital circuits with the best high-frequency capacities are employed in their design. By using time-aligned, ultra-short, 4-layer PCB traces, Aavik aims to preserve the natural sound quality of the wide and complex range of different signals. The DAC circuits are also fitted with ultra-low jitter onboard clocks.
You can also switch up-sampling on or off and choose between a slow (soft high-frequency roll-off) and a fast (steep high-frequency roll-off) filter.
The Aavik U-180 (€9,000), U-280 (€15,000) and U-580 (€30,000) are all available now.
