The NAP150x's good looks and compact dimensions discretely house an extremely fast, powerful and musical amplifier.

Designed with meticulous attention to detail, it sets new standards in its class with performance and flexibility to match.

The heart of the amp circuit is a version of the world class NAP 500 with a substantial and very quiet power supply using a custom designed and manufactured toroidal transformer.

Improvements over the original NAP 150 include: a new toroidal transformer for improved regulation; separate transformer windings for CH1 and CH2 and Pre-amp (the NAP150 combined CH1 and CH2 windings); an up-rated pre-amp power supply to improve the performance of the preamp.

Where required the NAP 150x can be used in most series of systems, both passive and active.
