Integrated Amplifier

Origine A2 evo

This integrated amplifier uses a new amplification architecture, with only two stages and no overall negative feedback: a very low distortion voltage amplifier and a very high capacity current buffer.

It has taken almost 5 years to improve the Origine A2 amplifier through working on “details” that, in combination, make a huge difference. The Origine A2 evo differs from the Origine A2 in two main respects:

  • The resistors upstream of the potentiometer use two separate technologies, different from those used previously. The result is better transparency and greater openness in the mid-high register.
  • A new technique for stabilizing the output stage negative feedback has been implemented. The result is perfect control of the most difficult loads (low sensitivity, low impedance speakers). In terms of sound, the image is incredibly stable with exceptional control of the low register.

As always at Neodio, balance is our mantra. Because music is made up of contrasts, and even paradoxes. Energy rubs shoulders with fragility, brutality coexists with gentleness.

The Origine A2 evo succeeds in proposing supreme balance, combining density and sound material on the one hand, and transparency and naturalness on the other. Whether your speakers are low or high sensitivity, Origine A2 evo will produce the best possible results.

Innovative technology for outstanding musical quality

The ultra-compact amplification circuit is assembled on a 4-layer printed circuit board. The Origine A2 evo incorporates a high-power supply with a 1000VA transformer combined with a bank of 16 VISHAY 105°C capacitors mounted on a Delrin support. The purpose this combination is to drain the high-frequency vibrations towards the bottom of the chassis rather than the amplification circuits. Zero Vibration technology is included in the Origine A2 evo through B1 supports and internal cabling. Home Cinema programming is possible for any of the 4 inputs for use as a power amp (maximum gain).

The ultimate integrated amplifier

input stage

The input stage is based on an operational amplifier with very low noise and high bandwidth. This drives bipolar transistors to create a voltage source without distortion or noise.

output stage

The output stage, with negative feedback, uses a set of bipolar transistors which drive 4 very high capacity MOSFET transistors (16A each).
