Parasound Halo A 31 Three-Channel Power Amplifier

Kal Rubinson has posted a review of the Parasound Halo A 31 three-channel power amplifier ($) in his Music in the Round column at Stereophile. His conclusions:

“The clean, luminous sound of the Halo A 31 was distinguishable from the slightly opaque treble of the Bel Canto Ref1000 Mk.2 monoblocks, though the latters’ greater power output might be an advantage in some applications. On paper, the Parasound is slightly less powerful than the McIntosh MC303 into 8 ohms, and somewhat more powerful into 4 ohms, at which impedance the B&W 800 Diamond swings from 60 to 800Hz. The Mac’s greater richness in the upper bass gave it a more authoritative, more forward sound, but its treble was a bit recessed compared with the A 31′s. The 800 Diamonds didn’t lack for midbass clout or for treble extension with the Parasound. In addition, at $3000, the Halo A 31 costs significantly less than either the McIntosh ($10,000) or the Bel Cantos ($5990/pair). ”
