Ultrasone NX-02
Hi-fidelity headphone amp designed for the PL750 and PL2500

The NX-02 Sistema gives a clear, natural sound with a sensational feeling of actually being there with the music. This system is manufactured in Italy and has exceptional detail, tight powerful bass and clear highs for an all around impressive listening experience. And with Ultrasone's patented S-Logic technology you can listen for hours with greatly reduced risk of hearing damage and fatigue.

The sound quality and performance are absolute. This amplifier can drive any headphone from 4 to 1000 Ohm, with distortion is so low that it is hard to measure.

Linearity is perfectly flat from DC to 100 kHz. 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 headphone amp uses operational amplifier's as signal amplifiers and a 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 solid state constant current generator.

NX-02 is a neutral headphone amp that gives your headphones a lot of punch.

The amplifier is totally silent, the noise floor is reduced down to the extraordinary figure of -113 dB, so it is the right choice for SACD.

This headphone amp offers headphone protection circuitry. If an unsafe condition is detected the headphone is immediately electrically disconnected from amplifier.
