Stack Audio launches a new audiophile USB music streamer

This is as true with digital audio as it is with analogue. The LINK has been built from the ground up to counter noise and interference. In particular, Stack Audio has spent the last five years investigating the effects of phase noise, working with legendary engineer John Westlake who has extensively researched phase noise and its effects on timing accuracy. 

At the core of the detox system is an ultra-low phase noise USB audio clock circuit. The ethernet input is synchronised to the audio clock toreduce the small variations in the timing of the digital signals.A dedicated USB audio output buffers the signal to purify it and EMI filter circuitry removes remaining interference.

The LINK is powered by an extremely low noise, multi-stage power circuit. Three independent switching regulators are synchronized to the audio clock ensuring that the fluctuations of the switching circuit are in time with the clock, reducing fluctuations and noise. The LINK’s bank of 9 low ESR capacitors and a triple linear regulated circuit further help to ensure the power source is clean.

The LINK’s sensitive electronics are protected in a high-mass case machined from solid aluminium. It features EMI shielding and is designed to absorb physical vibration. The LINK is finished in anodised black or silver because Stack Audio loves hi-fi and believes it should look as good as it sounds.
