NX-03 Class A currently not available

An extraordinary performer although a clean and simple amplification unit, encased in a fascinating hi-end box. An exercise of technology and design, to give the audiophile the best sound and the pleasure to own a piece of artwork.

The sound quality and performance are absolute, this amplifier can drive any headphone from 4 to 1000 Ohm. The Distortion (Linear, Harmonic and Intermodulation) is so low, at any frequency and level, that it is even very hard to measure!

The amp is completely linear from DC to 100KHz, and the damping factor is so high that this amp can easily drive small speakers.

No capacitors are used on the signal path, no global negative feedback is used.

The amplifier uses OPAmps as signal amplifiers and bias voltage servo actuator, in a simple but effective circuitry, with a very short signal path, and usage of few selected components.

The current output devices are Darlington Bipolar transistor assisted by a solid state constant current generator.

NX-03 still is extraordinarily fast, this added to the high dynamics and overall power, generates a sensational punch feeling. The neutral sound, deep-end controlled bass, and the transparent highs, are the best way to describe the sound of this small great amplifier.

The amplifier is completely dead silent; noise floor is reduced down to -113 dB, so it is the right choice for SACD, given the superior dynamic range.

A simple layout, an accurate selection of components, for a quality and performing design. Highest quality stainless steel casing, 10mm CNC machined faceplate, engraved faceplate graphics, chromed aluminum hand-made knob, give the NX-03 the right look for high class performing.

Thanks to totally dark floor-noise, NX-03 is a perfect combo with high-end IEM
