ADCOM GFA-5400 GFA-5400 Amplifier

The gfa 5400 is by no means outdated! Older model is more appropriate. It is one of the few amps in today's wattage game that bests it's claimed specs in every way. It is rated at all ch driven from 20 to20 (not at 20k w one ch driven) and rated at .05% distortion ( not 1%) and will drive 4ohm loads all day long. These amps are realistically putting out 140-145 wpc kind of like the rotel rb1080 rated at 200wpc but was bench tested at 235wpc. These amps will satisfy all but the most finicky loudspeakers, very controlled mid bass and bass. Overall excellent performance
