About the DS225

The Audio Research DS225 is a high-performance solid state stereo power amplifier that produces 225 watts per channel into an 8-ohm load. It uses Audio Research's proprietary Class D all-discrete analog switching MOSFET output technology combined with a large linear analog power supply, resulting in fast power delivery, cool-running efficiency, and low idle power consumption (35 watts idle). The amplifier is designed to be maintenance-free, reliable, and capable of driving almost any speaker with ease. It features a global feedback-free, fully balanced design with both XLR balanced and RCA single-ended inputs, dual Cardas patented binding posts, 12V triggers, and a 15A IEC connector. The DS225 offers superb bass control, dynamic impact, and a neutral tonal balance with a very low noise floor, allowing instruments to emerge clearly from silence. It is housed in a chassis the same size as the DSi200 integrated amplifier and is available in natural anodized or black anodized finishes. The DS225 was discontinued around 2014 but remains highly regarded for its sound quality and power efficiency.
