Aura Fidelity Audiophile Amp 110 Class A-A


















Traditional

The basic DNA of almost any  audio amplifiers has been the same for many years. You can clearly see  the three stages found in many audio amps. They are differential, voltage gain and current output stage. The design and building of these stages can be very advanced. It can also output alright and to a point beautiful music. However they are far from perfect.

​The mixing of feedback signal with pure input signal in the differential is a disaster.  Inverting the signal phase twice  through a not entirely perfect designed signal path results in a lot of small errors.

It results in a kind of “electronic fog. The biasing of the current output stage could be better with  new thinking and renewing.


Aura Fidelity has designed and built a totally different audio amplifier system.

It starts with two non inverting voltage gain stages with 1/25 gain. The first one works with the positive part of the signal phase, the other one the negative part. The distortion in these stages is close to zero. The signal gets energy from the non inverting current gain. From there it is directly transfered to the output current stage.

The design allows operation without any form for feedback. An advanced Bias Servo Circuit, free and independent of line swings provides max efficiency to the high linear output transistors.

The Aura Fidelity Audiophile AMP 110 stands for a superb music reproduction - it is well defined and pure over the whole frequency range. It is purely designed for audiophiles and music lovers.
