Here are the specs from NAD.... The "best buy" 2100 Power Amp is remarkable even by NAD’s standards. While its rated power for continuous test tones is 60 watts channel, it’s effective power output for music is an impressive 200 to 330 watts per channel (depending on speaker impedance). Thanks to NAD’s unique Power Envelope circuitry, this high level of tone-burst power is available not just for brief transients but for the full duration of complex chords and musical climaxes. Yet the 2100 has the same modest size and low price as other "50 watt" amplifiers with 40,000 µ F of power-supply capacitance, the 2100 delivers peak currents as high as 30 amperes to cope with the most complex and reactive loudspeaker impedances. In addition to power and control, the 2100 has delicacy; with a signal-to-noise ratio of 117 dB, it faithfully reproduces every subtle strand of low-level musical detail and back-ground ambience. With its high-speed output stage and ultra-low distortion, the clarity of its sound must he heard to he appreciated. If you need more power, a rear-panel switch combines the amplifier’s two channels to form a mono amp rated at 100 watts continuous and 500 watts tone-burst output. The efficiency and compact size of the 2100 also make it a perfect choice for hi-amplifying speakers. (Suggestion for a high-definition audiophile system: instead of buying exotic and expensive speaker cables to stretch across the room, install a bridged or bi-amped 2100 directly behind each speaker, connected with ultra-short wires.)
