The NAD 2200 is a power amplifier specifically designed for audiophile applications, offering a robust and dynamic sound performance. It features a power output of approximately 100 watts per channel into 8 ohms and 150 watts into 4 ohms, making it suitable for driving a variety of speaker configurations. The amplifier is constructed using a modular design, consisting of four distinct boards: an input board, a power supply board, and two main amplifier channels to optimize audio performance. Various capacitors play a crucial role in its operation, with modifications often made to enhance the amplifier's overall sound quality, such as replacing standard capacitors with high-performance alternatives like Nichicon and WIMA. The power supply retains a significant role, having been customized for improved dynamics and bass performance. The NAD 2200 is noted for its smooth delivery of audio across a wide range of frequencies, and modifications often focus on reducing distortion and enhancing the solid square wave response at lower frequencies. After numerous modifications and recaps, users have reported a marked improvement in transparency, detail, and overall dynamics in audio playback.
