Stereophile Guide to Home Theater, October 2003
"If that 2-channel test drive had me thinking about buying the A 51, the multichannel experience made me want to slap down my Visa card." "With music, the A 51 radiated sweetness and light. With action films, it rained thunder and lightning. There aren't many amplifiers that can so effortlessly cover both ends of the sonic spectrum." "Beautifully designed and skillfully executed, Parasound's Halo A 51 is all the amp anyone could need..." - Barry Willis
