"The Halo A 31 has a clear, detailed sound that belies its price, combined with just a touch of warmth. This blend of qualities made it a joy to listen to. Add to that its prodigious power output and rock-solid build quality, and I can assure you: It's the real deal."
Secrets of Home Theater and High Fidelity
"The Halo A 31 is a wonderful amplifier. By staying out of the way and letting me enjoy the music, the A 31 made this review a challenge to find new ways to say that it sounded wonderful. The Halo A 31 is able to drive any speaker you are going to throw at it and not complain, as well as impeccably built and beautiful in appearance."

"Remarkable definition…clean, luminous sound. Firm and extended bass. Running full range and full bore, I never lacked for power and weight."
