Description
Reference Analog Pre-amplifier with power supply
Our preamplifiers epitomise everything we believe in. Starting with our revolutionary NAC 12 back in 1974, Naim Audio preamplifiers have both rewritten the rules and set the standards for others to follow. The NAC 552 is second only to our Statement NAC S1: its distinctive two-box configuration marks it out from the competition just as surely as its unfettered musicality reflects our core values. It’s one of the best preamplifiers we’ve ever produced, and by extension, among the best in the world.
- Two-box configuration for optimum rejection of electromagnetic interference
- Split-rail power supply featuring 800VA toroidal transformer, three smoothing capacitors and new Discrete Regulator (DR)
- Fully suspended sub-chassis for superior isolation of sensitive circuit boards
- AV bypass mode for simple connection to an existing AV system
- Support for both DIN and RCA inputs to facilitate connection into a wider range of systems
- Independent listen and record banks for maximum flexibility
- Assignable inputs for enhanced usability with a range of sources
