HiFi Review (HK) December 2018
"If you are pursuing a cost-effective multi-channel amplifier, the A 52+ is a trust-worthy great value five-channel amplifier that worth having!"

Enjoy the Music July 2018
"At all volumes, the Parasound A52+ amplifier never gave ground, nor quarter, to the Martin Logan Summits. Electrostatic speakers are notorious power hogs, and the Martin Logan Summits are no exception. They are uniquely talented at exposing any amplifier weaknesses. Impressively, the Parasound A52+ five-channel amplifier didn't flinch."

Stereophile May 2018
"The Halo A 52+ provided all the power that my speakers could handle, and did so with aplomb. The soundstage was consistent with no blurring of indi­vidual voices or instrumental details. The new Parasound showed its superiority in more graceful smoothness in the upper midrange and treble, and low bass that seemed better integrated with the upper bass. Overall, I really liked Parasound's Halo A 52+ in every way."

Sound and Vision April 2018
"Listening with the Halo A 52+ in my system was a pleasure. Intense dynamic contrasts literally caused me to sit up straight on my couch. Stereo and multichannel music also sounded great, making it a versatile all-around performer for entry-level and advanced home theaters alike."
