NX-03 steel Class A headphone amplifier
An extraordinary performer although clean and simple amplification unit, encased in a fascinating hi-end box. An exercise of technology and design, to give to the audiophile the best sound and the pleasure to own a piece of artwork.
The sound quality and performance is absolute, this amplifier can drive any headphone from 4 to 1000 Ohm. The Distortion (Linear, Harmonic and Intermodulation) is so low, at any the 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 use OPAmps as signal amplifiers and bias voltage servo actuator, in a simple but effective circuitry, with 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 steel is extraordinary fast, this added to the high dynamics and overall power, generate a sensational punch feeling. The neutral sound, deep-end controlled bass, and the transparent highs, is the best way to describe the sound of this small great amplifier.
The amplifier is totally dead silent; noise floor is reduced down to -113 dB, so it is the right choice for SACD, given the superior dynamic range.
and many more..
