100 amp high current discrete stereo Amp, 2 X 150 watts - Digital Input - Balanced Line XLR - EzSetEQ 

In terms of raw power, the HK 990 is the most muscular amplifier ever to carry the Harman Kardon® name, more than capable of driving the most demanding loudspeaker loads without breaking a sweat. But the HK 990’s awesome power is nothing if not highly refined, extending beyond watts and amps. With a choice of discrete optical or digital inputs or an analog-only signal path, as well as fourth-generation Real-Time Linear Smoothing (RLS IV), 2.2-channel EzSet/EQ™ room optimization, dual subwoofer outputs and an audiophile-quality phono preamp section, the HK 990 offers a combination of features you'll find irresistible. Others, of course, may simply hunger for all that power. We understand completely.
