Product Description

Naim NAP155 XS  is a 60W per/ch power amp, and the perfect companion to the NAC 152 XS preamp in an XS system. It features a very large mains transformer - both physically and in terms of its power rating.


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.


We are here to help find the right system for you. As a suggested starting point, you may want to consider partnering the NAP 155 XS with the following:
Separates System:
- CD5 XS
- NAT05 XS
- NAC 152 XS

Upgrade Paths:
- Power-Line


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.

Press Reviews

  • When combined with the NAC 152 XS preamp, this power amp ticks many of the boxes but doesn’t have the wow factor needed to achieve five-star status. The Naim does a superb job of drawing out the framework of a piece of music and defining the leading edge of every note with real confidence. The NAC 152 XS/NAP 155 XS is a talented and well-thought-out duo that has many talents. It just lacks the polish and finesse of the top amps around. (What Hi-Fi Magazine)
