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."

"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."
