The NAC 252 descends from the NAC 52 - still one of the finest preamplifiers ever manufactured. It brings both control and connectivity advances over the NAC 52, and a significantly enhanced construction, aesthetic and finish. Its performance, too, is enhanced with the benefit of a decade of R&D bringing yet more speed, detail, transparency and music.
The Naim NAC 252 combines stunningly musical and accurate hi-fi reproduction with extensive flexibility to ensure it will remain at the heart of top quality systems for many years to come.
In addition to the preferred DIN inputs the NAC 252 owner can configure two of the inputs for use with the more common RCA phono connectors, allowing a wide range of non-Naim cables and components to be used. A user-configurable unity-gain input is provided for use with the AV2 processor or similar.
Each of the six inputs features separate listen and record facilities. In addition to the usual record mute, the NAC 252 mutes not only the output but also powers down all associated record circuitry, eliminating any possibility of degrading the main output.
Many designs were explored for the NAC 252 and a complete review of the circuit topology and components took place in accordance with the developments pioneered in preamplifiers such as the NAC52. Hundreds of hours were spent listening to various designs, ensuring that the harmony between music and technology was always maintained.
Precision rotary potentiometers with precious metal wipers are used to preserve music integrity and ensure long-term stability.
Ten independently regulated power supplies are fed from the matching SuperCap power supply. Totally separate regulated supplies for the digital control and switching ensure no noise is generated in the audio circuits.
