Soundstage Access April 2015
"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."

Stereophile September 2012
"Remarkable definition…clean, luminous sound. Firm and extended bass. Running full range and full bore, I never lacked for power and weight."

Amazing ! Priceless...

I really wanted to improve my front sound stage ( LCR )which was and is the most important part of my system for both music as well as movies and with my earlier set up my power amplifier was 150x5 channel's which just could not drive my power demanding speakers which are 89db to my requirement. I did my bit of research and that was the first time I stumbled upon The Audio Co to guide me to just what was my requirement. Yes it's the Parasound A31 Halo THX certified 3 channel power amplifier which did it all! The machine is heavy and it used one of the best toridol transformers which powers it up to 250x 3 undoubtedly. My power demanding speakers shine and now my system sounds like I am listening to a live orchestra playing. This machine does not consist of any auto cooling fans which are noisy like my earlier amp but has well built, good looking heat sinks to disperse any kind of heat (never heats up). Solid power and gives you that bang 250w/channel which sounds so smooth for music and awesome for movies. Parasound sure uses one of the best caps and components for their amps. Go for it!!
