An audio power amplifier (or power amp) is an electronic amplifier that reproduces low-power electronic audio signals such as the signal from radio receiver or electric guitar pickup at a level that is strong enough for driving (or powering) loudspeakers or headphones. Arc has been designing, building, and marketing a roughly 200w amp for decades (its reputation was, in part, made by the d150, the first high-powered audio research amplifier), but it has never built a better one (i've heard) than the new ref 250, which is everything that its most recent predecessors—including the reference 210—were not.
