Audio Research class-D Integrated
By John Atkinson Posted: Jan 13, 2010
Elsewhere in this report, Brian Damkroger writes about the new Audio Research DS-450 class-D power amplifier. However, I was more taken by the Minnesotan company's $5995 DSI200 integrated amplifier, which offers 200Wpc into 8 ohms, compared with the larger amplifier's 410W, and had its top off. (This is Las Vegas, after all.) The 93%-efficient class-D outputstage was developed in-house and is coupled with a hefty linear power supply.
