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.

Full Description

 

The ideal partner for our NAC 152 XS preamplifier or NAC-N 172 XS streaming preamplifier, the NAP 155 XS features a substantial, custom-designed toroidal transformer with separate transformer windings for each output channel. It delivers 60 watts per channel (into 8 ohms) and will become the musical engine of a modern or traditional hi-fi system, whether the source is a digital stream, CD or vinyl.


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.


Features

    60W per channel output into 8 ohms
    Internal power supply to allow direct connection of a NAC 152 XS, NAC 202 or NAC 282 preamplifier
    Custom-designed toroidal transformer with separate transformer windings for each output channel
