Stereophile December 2015
“I believe that J. Gordon Holt would characterize the Parasound Halo Integrated as neutral and accurate. Why? Because, with certain extravivid recordings, I perceived the Halo as tracking the input signal pretty close to the feeling of master tape. Likewise, it was neutral, in that well-considered, just-right Goldilocks way: It was never too anything-except, maybe, too inexpensive!”

HiFi Choice Editor’s Choice (UK) December 2015
“If there was ever a product that personifies the modern integrated amplifier, this is it. There’s nothing not to like about this great value mid-price integrated.”, October 2015
“I suspect that many audiophiles who never anticipated wanting or needing an integrated amplifier may find, someday, that they do need a compact yet powerful one. If that is the case, they may find that the Parasound Halo Integrated 2.1 amplifier is the high-value solution. For $2495 it includes a powerful basic amplifier coupled to an excellent preamplifier that includes a built-in analog crossover as well as a DAC that supports all modern formats.”

The Absolute Sound 2016 High-End Buyer’s Guide
“For many audiophiles such mid-priced components will deliver a high enough level of sonic excellence to make for joyous listening for many years to come.”, September 2015
“Its performance blew me away, and its incredible bass-management capabilities make it stand apart in what is slowly but surely becoming a crowded integrated amplifier market. I’d say Parasound has a winner on its hands here… especially for the price.”

Lyd & Bild (Norway) September 2015
“The Parasound Halo Integrated Amplifier is one of the really exciting amplifier purchases one can make for under 30,000 kroner. Here is the power to breathe life into a party house with resolution and musicality in spades. The amplifier is ideal for driving expensive high-end speakers, while it can help less expensive speakers realize the promise of their full potential. Sound-wise the HINT is slightly full bodied, but it is neutral enough so the speakers are what determines the final sonic signature. The little fullness that’s there is like magic washing over us, and we can sit and listen to music for hours. And that’s what it’s all about!  If you have 30,000 kroner to spend on an amp and compare it against others, its ingenious subwoofer output with high and low pass crossover filtering, in addition to its fairly lavish phono stage, should nudge you in the direction of the Parasound HINT. Even if you don’t need these, it is still a bargain.”, August 2015
“So as I said, I wanted the Parasound Halo Integrated to shine, and I got what I wanted. It concentrates on sound quality while including home theatre passthrough, subwoofer output, bass management, high resolution digital inputs, a decent phono input stage, quality headphone output and tone controls in a conservatively styled package. When you take a look at what Parasound is asking for this component, just $2495 in black or silver finish, you may well be as impressed as I am. I’m going to miss it around here.”

Cnet, June 2015
“The Halo Integrated transformed the sound of the .7s. Really dynamic recordings, like Antonio Sanchez’ drums solos on the Birdman soundtrack amply demonstrated the Halo Integrated’s muscle.”

New Record Day, August 2015
“The bottom line—my absolute favorite thing about the Parasound Halo is its no-nonsense approach of simplicity combined with feature-rich tools when you are ready to push the limits of what the Halo Integrated has to offer.”
