A 51 Amplifiers

A 51 Reviews: 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 Hi-Fi Choice (UK), July 2003 "Robust engineering rather than radical technology sees the THX Ultra 2-specified A 51 power amplifier through the day." "...the Parasound duet (C 1/A 51) allows the most substantial loudspeakers to melt from the scene." "...rest assured that the performance of the C 1 and A 51 is as flexible and impressive as you could hope for." Editor's Choice - Paul Miller Video (Germany), January 2004 "Mit souveräner Kraft und perfekter Harmonie führt die edle Vor-/Endstufen-Kombi von Parasound direkt ins akustische Nirvana." = "With precise force and perfect harmony the noble preamp/amplifier combination from Parasound takes you directly to acoustic Nirvana." - Jürgen Schröder DVD Etc., May 2003 "The bass extension is simply wonderful: copious, deep, taut, and rhythmic." "The experience is so strong, that I found myself in musical nirvana..." "It is a superlative performer in the $4,000, multi-channel amp category..." Rating 98 - Manoj Motwani, M.D. Widescreen Review, September 2003 "From the outset, I have to say that the Parasound A 51 multichannel amplifier delivered impressively clean, effortless, detailed sound." "The Parasound Halo A 51 multichannel amplifier, with its top-notch performance for movies and music, deserves a very strong recommendation for anyone serious about quality home theatre and surround music sound." - Perry Sun T 3 (UK), September 2003 "The A 51 has so much grunt, grip and grace, you have to restrain yourself from cranking up the volume until the walls start to ripple Matrix style." "Its high price pitches it against formidable opposition, but the C 1/A 51 pairing more than holds its own, with a combination of massive power, killer dynamics, fine transparency and user flexibility." T 3 Five Star Gold Award - David Vivian What Hi-Fi (Russia), April 2003 "All sounds - from leaves rustling and rain, to rifles and a train's roar - are reproduced very plausibly, without any tint or digital "dirt" from compressed audio formats such as Dolby Digital. Soundtracks sound excellent, regardless of genre. Voices of actors, their emotions - all sound very plausible, giving true pleasure to any film fan. Special sound effects so loved by mystery and thriller creators are magnificent. During 'The Call' the viewer remains literally chained to the armchair. Creaks, leaves rustling, steps - all so realistic that it forces even people with nerves of steel to shudder. In a word, an outstanding set. Listen to it – you will not regret." 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." Home Theater Buyers Guide, 2004 Featured component in Stepping Up Your System article. "Sky is the limit" system.
