The LINK II is a digital audio bridge that accepts music files “streamed” from internet subscription services (like Spotify, Tidal, Qobuz etc.) or music files that you might already own and links them to your HiFi system.
Stack Audio has always been focused on source devices, after all, it’s where everything starts. Introduce noise and distortion at the start of the playback process, it damages and disrupts our enjoyment of the music, as a result, the LINK II has been built from the ground up to remove unwanted noise. Your favourite music sounds more realistic and immersive. The LINK II’s new clock has 50% lower phase noise in contrast with its predecessor, Stack Audio’s LINK.
Power supplies are essential to energise circuits and make electronics work. Everything starts with power. However, if they are not implemented well, they can add noise and distortion. The LINK II’s advanced digital processors are powered by uniquely designed, exceedingly low noise, multi-stage power circuitry.
The clock system is the heartbeat of any digital system, it manages and creates a mathematical reference for the various protocols to work from, be that Ethernet or USB.
In our world, that of digital audio file playback, multiple clocks, all running at different speeds tend to cause noise and jitter problems. We typically hear this as it gives an edgy or brittle quality to the sound.
The accuracy and reliability of the clock system, therefore, has a direct influence on the performance of the product.
The LINK II uses an ultra-low phase noise oscillator. Here at Stack Audio we went to great lengths to extract the absolute performance from this clock. It starts by powering it with an exceptionally clean supply. In addition to this, we synchronised the ethernet, USB and the PSU to the audio master clock resulting in one coherent and extremely accurate device.
This ensures that the fluctuations of the switching circuit are in time with that of the audio clock reducing fluctuations and noise. The three independent switching regulators are synchronized to the audio clock, thus when the PSU switches frequencies it is in time with the master audio clock removing clashes and interference.
Solid Aluminium Case
The LINK II is a pure digital system housed in a thick CNC machined aluminium case enclosed with EMI absorbing material. This ensures noise does not escape and enter the analogue domain nor does noise enter and affect the clock circuit.
The LINK II is designed to be as easy to use as possible. You do not need to download new software or learn a new control app to make it work, you can continue to use your favourite and familiar software to control and send music to the LINK II. Afterall companies like Roon, Audirvana, Spotify, Tidal etc. have already invested considerable resources into delivering world class software, which most of us already know how to use.
