Naim NAC 552 Preamplifier - White LED Logo
Details
Distinctive Two Box Configuration
The NAC 552 is the first part of a distinctive two-box configuration consisting of the NAC 552 preamplifier and the 552 PS power supply. Simply put, it's one of the best preamplifiers Naim have ever produced and is considered among the best in the world.
Setting The Standard
The NAC 552 epitomises everything Naim believe in. Starting with the revolutionary NAC 12 back in 1974, Naim Audio preamplifiers have both rewritten the rules and set the standards for others to follow.
Unfettered Musicality
The NAC 552 is second only to the Statement NAC S1: its distinctive two-box configuration marks it out from the competition just as surely as its unfettered musicality reflects Naim's core values.
Electromagnetic Interference Rejection
The concept behind the distinctive two-box configuration is simple. Separate the power supply entirely from the pre-amplifier by placing it in a separate component power supply. This ensures that the systems electromagnetic interference rejection is as optimal as practically possible.
Discrete Regulator Technology
The split-rail power supply features an 800VA toroidal transformer, three smoothing capacitors and a new Discrete Regulator (DR).
Suspended Sub-Chassis
The fully suspended sub-chassis provides superior isolation of the sensitive circuit boards within the amplifier.
AV Bypass
The AV bypass mode simplifies connecting your Naim stereo system to an existing AV system, meaning it's possible to enjoy the musical performance of your amplification in tandem with your home cinema equipment.
Wide Connectivity
Both DIN and RCA inputs are supported to facilitate connection to a wider range of systems, whether they're Naim-centric or from alternate manufacturers. What's more, assignable inputs enhance usability with a range of sources.
Flexibility To The Fore
Independent listen and record banks provide maximum flexibility for music lovers.
Technology And Craft
Every component of the dual-box NAC 552 has been developed using the latest technology and the finest materials available. The NAC 552 has sensitive electronics mounted on a base sub-chassis and fully suspended on coil springs to minimise the impact of vibration.
Precision Components
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.
