Technology & Craft
Every component in our flagship 500 Series range, including the NAC 552, has been developed using the latest technology and the finest materials available. We've gone to great lengths to ensure that the two-box design is a true reflection of Naim Audio's classic style, with the power supply components housed in a separate enclosure to achieve minimal electromagnetic interference.
The NAC 552 has sensitive electronics mounted on a brass sub-chassis and fully suspended on coil springs to minimize the impact of vibration. Precision rotary potentiometers maintain musical integrity and ensure long-term stability. The device has six inputs that can be selected from the front panel or remote control, including two RCA phono-type connectors for alternative components.
