The NAP 155 XS is the perfect companion to the NAC 152 XS audio preamplifier in an XS system. It features a very large mains transformer - both physically and in terms of its power rating - and at the heart of its power supply uses the same reservoir capacitors as the award-winning SUPERNAIT integrated amplifier.

The NAP 155 XS employs similar construction techniques to the NAIT XS integrated amplifier with a castellated heat-sink and reduced earth reference routing to deliver enhanced performance and more music. The NAP 155 XS is a power amplifier straight out of the classic Naim mould: fast, detailed, dynamic and single-mindedly musical.

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 previous NAP 150x include: a new toroidal transformer for improved regulation; separate transformer windings for CH1 and CH2 and preamp; and an up-rated preamp power supply to improve the performance of the preamp.

Where required the NAP 155 XS can be used in most series of systems, both passive and active.
