A DAC WITHOUT A CHIP – A SOUND WITHOUT BARRIERS

At the heart of the SD-188 is Aavik's exclusive Continuum DAC. Instead of a traditional chip, a programmed FPGA circuit is used to convert all digital audio to high-resolution DSD512 – a format that is close to analog reproduction. A custom-made digital filter ensures a smooth, natural signal transition without switching, while simple analog filtering completes the signal path. The result is an undisturbed, organic and deeply realistic audio experience.

STREAMING ON YOUR TERMS

The SD-188 supports both DLNA 1.5 and UPnP AV 1.0 protocols, giving you the freedom to stream from a wide range of network sources and devices. Whether you're playing from your music server, computer or network streamer, the signal is treated with the same respect and precision all the way to the output.

INPUTS FOR ALL YOUR DIGITAL SOURCES

The rear panel offers both flexibility and finesse. The SD-188 is equipped with two BNC inputs, two optical TOSLINK inputs and a fully galvanically isolated USB input, which supports asynchronous PCM up to 384 kHz and native DSD up to DSD256. A BNC digital output and analog RCA line outputs make integration into your system simple and uncompromising.

NOISE REDUCTION THAT MAKES AN AUDIBLE DIFFERENCE

The SD-188 is equipped with a whopping 36 active Tesla coils and 72 active square Tesla coils. These circuits work actively to combat electrical noise and voltage spikes – creating a calm background where even the finest nuances in the music can unfold. It’s technology you don’t see, but you hear from the first second.

DITHER TECHNOLOGY THAT OPENS UP THE SOUND IMAGE

Aavik's 3rd generation analog dither technology is based on radar inspiration and sends precisely tuned anti-phase signals that significantly lower the noise floor. The SD-188 uses three independent circuits that work purposefully to free the signal from digital artifacts and highlight the smallest details. The sound image becomes more vivid, more three-dimensional - and more human.

MUSIC IN THE CENTER

The power supply in the SD-188 is developed with the same resonant mode technology known from Aavik amplifiers. It delivers smooth, sinusoidal current and adapts the frequency to the load. This means extremely low noise and a clean foundation where every note rests in balance – even when the music demands sudden energy.

DESIGN THAT INSPIRES CONFIDENCE

Like the rest of the x88 series, the SD-188 is the result of the creative collaboration between Flemming Erik Rasmussen and Michael Børresen. The design is functional, intuitive and elegant – with a focus on materials, resonance control and visual calm. The SD-188 fits into any aesthetically conscious setup, but will always catch the eye and signal seriousness.
