PowerSwitch A2

Ethernet Distribution

Spacious presentation of a pristine sound

The Ansuz PowerSwitch A2 is equipped with other Ansuz technologies that significantly amplify the music signal and add more energy to the music, which is presented on an expanded and holistic soundstage.


Technologies and Components

Clean streaming signal.

The Ansuz PowerSwitch has been designed with the aim of delivering a very clean streaming signal to the hi-fi system. To achieve this, Ansuz employs its most advanced and truly groundbreaking audio technologies of noise reduction and resonance control. Ansuz audio technologies ensure that virtually no noise is transmitted from the PowerSwitch to the audio components.

Natural-based composite cabinet material

The cabinet design is an important Ansuz characteristic and is design to eliminates sonic distortion. The disturbing sonic influence, which emanates from the material the cabinet is made of – mostly aluminium – results from its mechanical resonance. To eliminate this sonic distortion, the challenge was to minimize the use of aluminium in the cabinet. Ansuz’s sister company Aavik began testing various materials and 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 Ansuz’s quest for the ultimate music experience.




The Tesla coil principle

The key operating principle of the Ansuz Tesla coil is to have two coils wound in opposite directions – one coil and one counter coil. In Ansuz words, this is called “A double inverted coil”. The two coils both carry voltage, and when one of the Tesla coils encounters a voltage spike, a counter spike is activated to eliminate the noise. Since noise spikes are pure voltage carrying virtually no charge, the cancelation is quite good, but not perfect. Adding more Tesla coils in parallel, increases the noise cancellation and the perceived blackness in the music increases significantly along with the purity and clarity of the sound. Ansuz uses various types of Tesla coils, as their individual properties ideally complement and reinforce each other.



Active cable Tesla coil

Active anti aerial protection.

The active cable Tesla coil is wound directly on the outer part of the cable and protects the signal from absorbing the airborne RF noise. This noise is absorbed in the Tesla coil. The active version is about three to four times more efficient than the Passive cable Tesla coil.


Active square Tesla coil

Embedded efficiency.

The active square Tesla coils are embedded in our printed circuit boards – a coil on the top and the counter coil on the back. The principle is exactly the same as the active Tesla coil and thus has a greater ability to eliminate noise than the passive Tesla coils.





Analog Dither technology

Musical information from the depth.

Analog dither technology originated in radar, where it ensured a stronger signal and thus greater range. Ansuz adopted this technology. Their active Tesla coils send pulsating signals at precisely defined frequencies. These signals are sent in anti-phase. This significantly amplifies the musical signal and eliminates the background noise floor.




Built in Ansuz PowerBox

Ansuz PowerSwitch features the Line/Digital section from the Ansuz Powerbox. This section transfers and adds even more noise cancelled signal from the Ansuz PowerBox to the more advanced series of Ansuz cables.

"A side note... I don't tend to list the music we play when listening or reviewing simply because it becomes more of "what do you want to hear"... and it goes from there. Our tastes range from noise to alternative to post-punk to reggae to rock to industrial to ambient to shoegaze to slow core to hardcore to punk to electronic to... well, pretty much anything but classical, jazz, country, and female vocals." - Dave Clark

"Anyone who invests in a switch even under such conditions can benefit from the sonic enhancement and is thus technically prepared for a further expansion of his music network. However, the switch is no substitute for a high-quality connector cable. Very soon Dirk Sommer will reveal in a test whether a low-cost optical Ethernet connection is a good solution, or not. This is where we stop for today, be continued in a few days." - WOLFGANG KEMPER



"In my system, however, the Audioquest took the lead. That probably would be significantly different if my system was completely equipped with power cables from Ansuz instead of Audioquest - at least according to my theory and conviction. Ansuz as well has complete power concepts on offer, including line filters and the Sparkz noise suppressors as well as a grounding concept. " - WOLFGANG KEMPER

"The Ansuz X-TC is an excellent network switch, the A2 is a clear step better with
higher resolution, better timing and an ability to open up the soundstage that’s very appealing. The need to keep noise at bay means that the switch is as important a part of a streaming system as the streamer and DAC, the lower the noise the more natural and revealing the system. Adding Ansuz’s matching A2 power and ethernet cables allow it to do an even better job and bring clear benefits in a revealing system, if you want to hear as much music as possible they are a key part of the package." - Jason Kennedy
