Technology & Craft

The NAP 155 XS is flexible enough to be used in most types of systems, both passive and active but retains an unwavering focus on performance.

The heart of the amplifier 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 its predecessor, the NAP 150, include: a new toroidal transformer for improved regulation; separate windings for each channel and preamp; and an up-rated preamp power supply to improve the performance of the preamp.
