The Audia Flight Strumento N1 is a high-end stereo preamplifier designed for maximum signal purity, speed, and precision. According to Audia Flight, the purpose of a preamplifier is to pass the original audio signal through without coloration or loss. The Strumento N1 uses fully balanced circuits, a discrete Class A current feedback amplifier stage, and high-quality constant impedance volume control. The volume control consists of high-quality resistors and relays and operates in 0.5 dB steps with a wide control range. This ensures that signal integrity is maintained at every volume level. The amplifier stage uses independent power supply sections per channel and a Class A MOSFET output stage designed to drive virtually any power amplifier. The enclosure is made of high-quality CNC-machined aluminum. Inside, the Strumento N1 uses four toroidal transformers, separate power supply sections, and high-quality components to keep noise and distortion as low as possible. The design is focused on a very wide frequency range, high dynamics, and maximum transparency.
