Naim NAP 155 XS Power Amplifier

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 NAP 155 XS employs similar construction techniques to the NAIT XS integrated amplifier with a castellated heatsink 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.
