The DS450 stereo power amplifier is the second member of the "Definition Series" from Audio Research. With a muscular 450 WPC into 8 ohms and stunning sonic performance, the DS450 provides high performance, high efficiency and high value.
Designed entirely in-house by our engineering staff, the DS450 is a balanced differential design with zero global feedback. Many proprietary parts are incorporated, including our own custom designed transformers that are manufactured in the US, our own litz internal wiring, and filters that we hand wind in house. In fact, it is not merely assembled here, every amplifier is entirely hand-made from the ground up in our Minnesota facility where it is tested, burned-in, and evaluated in a reference system before being shipped to its new home.
