Product Highlights

"The Audio Research DS450 is a high-power Class D stereo amplifier delivering 450Wpc into 8 ohms and 700Wpc into 4 ohms. Utilizing a discrete analog switching-MOSFET output stage rather than off-the-shelf modules, this unit maintains the classic Audio Research sonic signature—open, warm, and detailed—while offering the efficiency and cool operation of modern technology. The design features a massive power supply and high-quality internal components that ensure a transparent soundstage and immense power delivery. It is an ideal solution for driving demanding speakers, such as Magnepans, providing a practical yet high-performance alternative to traditional tube amplification.



Reviewers praise the DS450 for its surprisingly tube-like clarity and massive, controlled bass response. While some find it slightly forward in specific configurations, most value its relaxed, engaging character and extremely low noise floor. This amplifier provides a sophisticated balance of power and musicality."
