During development it proved impossible not to make concessions if the designer would have utilized one of the already established techniques. Therefore this particular route was abandoned and a design was created where voltage gain is achieved via a so-called step-up transformer, instead of transistors or tubes. Only two FET transistors are utilized to convert the signal from the step-up transformer into power, which plays into the strength of these semiconductors.
By utilizing this method the Aurix has become a design free of concessions, where the integrity of the sound of tube-amps is combined with the compact practicality of the transistors, without any of their inherent flaws.
The Aurix is a 100% class A amplifier with a very high signal-to-noise ratio and almost no distortion. Because feedback has not been implemented in the design the Aurix has no degradation of the incoming signal in terms of dynamics and imaging.
In order to ensure the Aurix is flexible and applicable for most headphones it has two gain factors so that both low and high impedance headphones can be utilized. Aside from that the Aurix is equipped with two controllable analogue inputs that, in case no headphone is connected, can loop the signal back to your set. This allows the Aurix to be permanently installed in your hifi-set without you ever having to switch the cables around.
The Aurix’s appearance is made the match the Octave Mk II, but works very well with all high-end analogue sources such as the Hex DAC.
It is available both separate and in combination with either Octave Mk II or Hex with an attractive discount. See options.
