Multi Channel Power Amplifiers : Parasound Halo A51 THX Ultra2 250w X 5 Amplifier

Parasound Halo A51 THX Ultra2 250w X 5 Amplifier

Stereophile Guide to Home Theater, March 2004
AAA Recommended Component - "I expected the A 51 to sound good. What I wasn't prepared for was how good it sounded right out of the box. Its midrange was totally seductive, its soundstaging and imaging abilities in the same league as some of the best gear I've ever heard at any price."

"The A 21 and A 51 amplifiers are both loaded with usable features above and beyond most other amplifiers in todayÝs market." "The Parasound A 51 is more than capable of driving any speaker load in even the most demanding home theater systems." "The linearity of this amplifier is excellent at any power level it is operating in, and its freedom from audible noise and distortion makes it a true winner!" "The Parasound Halo A 21 and A 51 are top rate amplifiers at a great value. Parasound seems to have attended to every aspect of their design including the excellent build quality internally and externally matched with great looks." Overall Rating: 5/5 Stars - Ken Stein and Steve Dellasala
