NAC S1

About the NAC S1

The Naim Statement represents the pinnacle of Naim engineering, consisting of the NAC S1 line preamplifier and NAP S1 mono power amplifiers. The system features a modular three-tower design with a distinctive vertical form optimized for efficient cooling and separation between the massive power supply and sensitive electronics. The NAP S1 employs a revolutionary split topology with a class-A voltage gain stage physically separated from a class-AB current gain stage, allowing the voltage amplifier to operate with the purity and speed of a preamplifier without driving speaker loads. The system incorporates zero global feedback and uses positive feedback error cancellation for the output stage. The NAC S1 preamplifier features a proprietary dual-action volume control that combines a 100-step resistor ladder attenuator with Cirrus Logic chip control, switching between the two for optimal sound quality. All audio signal paths are kept as short as possible with three-dimensional layout to minimize electromagnetic interference. The chassis design includes suspended circuitry to prevent microphonic interference, with each transistor potted for mechanical damping. Custom-designed speaker binding posts and WBT NextGen RCA sockets accommodate heavy, thick cables.
