Good Sound, December 2004
"My son began dancing while I played this CD through the Parasound combo (P 3/A 23) - they passed the toe-tapping test with flying colors." "...the Halo A 23 never sounded strained, nor did the sonic picture lose coherence or take on unwanted coloration with the increased volume." "Parasound's Halo P 3 preamplifier and Halo A 23 power amplifier are sexy in appearance, easy to use, and sound solid and satisfying." "Good value and good sound: a winning combination!" - Eric Hetherington

Editor's Choice Recommended Product - Power Amplifier under $1,000
Home Cinema Choice (UK), March 2004
"125 Parasound Watts carries a lot more grunt in the real world than a similar number of Watts from most AV amps, as our lab test prove." "...the system is powerful, engaging and very listenable, even when pumping the bass cones as though there was no tomorrow." "Power reserves are high and the whole effect is one of control, good definition and kick ass authority." "...a superb package (C 2, A 52, A 23), whose power and majesty can only be hinted at on the printed page, and tremendous material value for money too. Audition with urgency." 4 1/2 Stars - Alvin Gold |
