NAIM NAC 112X + NAP 150X

Pre owned. In excellent condition. Free from noticeable signs of wear. Supplied with remote control and original packaging.

The combination of the Naim NAC122x preamplifier and NAP150x power amplifier represents one of the most accessible entry points into Naim Audio's design philosophy, offering a separates system that brings much of the technology and sonic character of the company's higher-end components into a more affordable range. Designed to operate as a perfectly integrated system, these two components deliver their best performance when used together with Naim's dedicated cables, following the British manufacturer's philosophy of achieving maximum electrical and sonic consistency.

At the heart of the design is a distinctive engineering approach that sets Naim apart from most Hi-Fi manufacturers. The connection between the preamplifier and power amplifier uses the company's proprietary 4- and 5-pin DIN connectors, a solution developed to create a single grounding point between components while minimizing hum, interference, and grounding-related noise. Naim's renowned NACA5 loudspeaker cable is also specifically engineered to maximize the stability and performance of the company's power amplifiers, preserving the intended balance of the original design.

Another defining feature is the preamplifier's power supply arrangement. The NAC122x does not incorporate an internal power supply, instead receiving its power directly from the NAP150x power amplifier. This design eliminates the transformer from the preamplifier chassis, reducing the influence of electromagnetic fields on the sensitive audio circuitry. Performance can be further enhanced by adding dedicated external power supplies such as the FlatCap 2x or HiCap 2, providing improvements in transparency, dynamics, and overall control.

Compared with its predecessor, the NAC122x introduces several refinements. Volume control is handled by a low-noise motorized Alps potentiometer selected for its superior sonic performance, while input selection is managed by relays to ensure a cleaner signal path. The remote-control circuitry and electronic switching automatically enter a low-noise state when not in use, further reducing the system's noise floor. The Tape and Subwoofer outputs are buffered and isolated from the main signal path to prevent any impact on audio quality.

Despite its modest 50-watt-per-channel rating, the NAP150x delivers remarkable driving capability and dynamic authority, performing like a significantly more powerful amplifier. Its generously specified power supply and fast circuitry ensure excellent control, precision, and stability, even with demanding loudspeakers and during complex musical passages.

Sonically, the NAC122x and NAP150x embody the qualities that have made the British brand so highly regarded. Their presentation is characterized by speed, rhythmic precision, and exceptional dynamic performance, combined with a highly neutral tonal balance and an extremely low noise floor. Music is reproduced with outstanding timing, fluidity, and naturalness, revealing every musical nuance without adding artificial coloration.

The soundstage is spacious, precisely focused, and convincingly layered in depth. Vocals are reproduced with remarkable transparency and expressive detail, while acoustic instruments retain their natural harmonic structure. Even energetic recordings benefit from the amplifier's speed and composure, maintaining excellent control and clarity at high listening levels.

The NAC122x and NAP150x offer an ideal solution for listeners wishing to enter the world of Naim separates without compromising the engineering principles that have defined the brand for decades. Their combination of rigorous design, outstanding build quality, and engaging musical performance delivers a dynamic, precise, and highly involving listening experience that faithfully reflects the philosophy of the historic British manufacturer.
