The NAP 155 XS is the perfect companion to the NAC 152 XS 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 NAP155XS 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
