The Halo A 51 is everything a great amplifier should be. Guided by legendary designer John Curl, we created a five-channel amplifier with sonic qualities usually reserved for ultra high-end stereo models. Its 250 watts per channel assures effortless reproduction of musical crescendos and movie special effects, while our exclusive class A/AB operation places the A 51 in a league by itself. As a rugged and refined workhorse, the A 51 will provide many years of high end audio enjoyment.
