NAC 252 Pre-Amplifier

NAC 252 Pre-Amplifier

Like many Naim products, the NAC 252 stems from good stock: it descends directly from the NAC 52, still one of the finest preamplifiers ever made. Capable of exceptional clarity, its power supply components reside in a separate enclosure: the SuperCap power supply unit. This ensures optimum isolation from electromagnetic interference and provides each of the ten audio circuits with an independent, fully regulated supply voltage. Additionally, separate power supplies for the digital control and switching circuitry further isolate the audio circuitry from noise. It’s this attention to detail that makes the NAC 252 so special – that, and Naim's determination to let nothing stand in the way of your musical enjoyment.

Features:

• Support for both DIN and RCA inputs to facilitate connection into a wider range of systems

• Totally separate regulated supplies for digital control and switching circuitry
• Precision rotary potentiometers with precious metal wipers
• AV bypass mode for simple connection to an existing AV system
• Powered input for use with StageLine or SuperLine phono stages
