The NAP 155 XS power amplifier 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. It makes the perfect match for the NAC-152 XS and NAC-N172 XS pre-amplifiers.

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.


Why is this item collection only?

This is because some items require more setting up than others (e.g. multi room systems) or have advanced settings.

To ensure you get the most from your equipment we need to take you through the process of setting it up correctly.

Sometimes the equipment is simply not suitable for shipping (e.g. glass stands that have been built up).

Simply reserve your product today and then arrange to pick it up from your nearest Audio-T store.

Items showing as "In Stock" are within the Audio T group and we may need additional time to transfer to your selected branch.
