Delta 3 Stereo Amplifier from Classé
By Larry Greenhill Posted: Jan 10, 2017
Classé premiered its new Delta 3 amplifier series at CES 2017. Rated at 350Wpc RMS, the Delta 3 Stereo ($10,000) employs lateral MOSFETs in its output stage and 234,000 microfarads of German-made 4-pole Mundorf electrolytic capacitors in its power supply. These capacitors are said to offer lower equivalent-series resistance (ESR) and equivalent-series inductance (ESL) than other brands. The lateral MOSFETs require less current drive, and have a higher slew rate in their Delta 3 circuitry, which delivers 10% of its output power in pure class-A. Classé's Dave Nauber announced that both the stereo and mono versions of the Delta 3 will be available by mid-year 2017.
